'96 Vette LT1 into a '96 S10

D.Snutz · 11-12-2009, 01:58 AM

So, I've been dormant for a couple years now, but I'm getting back into the truck. I used to be in Norfolk, then in Bremerton, but now I'm out of the navy and living in Seattle. Love it here.

To date, I've got this on the 1996 4.3L 2WD Regular cab:
Baer track brake system
2/3 drop
Powertrax LSD
F&R sway bars
intake & exhaust
SCAT procar seats, custom center console, steering wheel, B&M ratchet shifter
Poly bushings all around (noisy as hell)
255/40/17 wheels & tires

I picked up a 1996 LT1 Vette motor & 4L60E trans for $950 and the engine looks pretty clean. I got everything off of it, down to the heads. I need to find a shop in the area (suggestions? by the look of the emptiness of the NW thread, I doubt it) and send the bottom end.

Now it's decision time. I definitely plan on a T-56, but those are proving hard to find in the used market. I may settle on a T-5.

I'm looking at http://www.summitracing.net/parts/TFS-K304-430-400/ for a top end kit.

The question is, do I rebuild the bottom end, or just have it cleaned up? If I rebuild the bottom end, wouldn't it make sense just to stroke it? Could I run a Scat or Eagle bottom end, similar to http://www.summitracing.net/parts/SCA-1-91100/ ? Would that work with the top end?

This will have to be a streetable vehicle; I plan on passing emissions with it. Am I out in la-la land with this?

I got the computers and wiring harness that went with the engine in the first place; are they going to work with my BCM? How's that wiring gonig to be?

Thanks for your thoughts!

Jared at Current Performance can hook you up with a plug and play wiring harness.

If you're looking to pass emissions, you'll probably have to run all of the O2 sensors for the LT1. You'll probably have to use some kind of stock style cats in the exhaust.

I don't see why stroking it would make the emissions any worse.

The "top end kit" you listed isn't exactly a top end kit. It's a cam and lifter kit. Top end usually includes a cam, heads, and intake. Idk, but to me that cam seems a little large. How much power are you trying to make?

The rotating assembly you listed would work fine. You would just need a nice set of heads to go along with it. No point in increasing the cubes if you're not gonna let it breathe better.

Hello, 03 Blazer... You seem very knowledgeable and in Gulfport...me too.

Hey, quick question, I'm wanting to buy a 91 S10 with a tuned-port corvette engine in it. I have yet to see this thing except for online.
Do you think that it'll be fairly good on gas?

dont go for the t5....hold out for the t56! u wont regret it...and X2 on the calling jared at CPW....I have a 95 z28 lt1 in my truck, ALL emissions on it, and passed emissions without a hickup at all.

It should as long as it's tuned properly and everything is working as it should.

Engine mods, transmission, gears, and tire size all play a part in fuel economy as well... If you have any more questions, PM me. It's not polite to thread-jack.... even though everyone is guilty of it at some point.

D.Snutz · 11-20-2009, 05:14 PM

Strange...I thought I had replied to this. Here we go again, then:

I'll keep Jared at CPW in mind when I get to the reassembly stage. I am definitely looking to pass emissions; this needs to be 100% streetable as an (almost) daily driver. I understand that I'll need O2 and cats.

The guys over at LS1tech.com suggested that a full 383 stroker would need too big of a cam to meet emissions, and that I should consider just a 355.

Somehow, I grabbed the wrong part number on that somehow. I was looking for the Trick Flow 430 top end kit. Looks like I grabbed a p/n from the parts list of the kit somehow. Sorry about that!

The goal was originally 400 to the wheels, but it doesn't look like I can swing that NA and still pass emissioins.

Llorracs: I found an LT1 T56. A bit pricey, 850 + shipping, but I manned up and forked it over!

Got any other thoughts?

**03blazer** · 11-20-2009, 05:48 PM

Just do a nice rebuild with some new pistons that will put you somewhere close to a 10:1 CR, add a nice cam (not too big), and get some port work done on the heads. I'm sure you'll be more than happy with it, especially with a T56.

Once you get ready to do it, call Jared and he'll hook you up with a complete plug and play wiring harness setup specifically for your truck and setup. Other things you'll neet will include mounts, headers, cooling system, etc...

Should be a fun truck once you get it in there.

let me put it to you this way...when i first had my truck done with the stock lt1 and t56, i took my uncles out for a ride....the crazy one hanging on the front of my bed with no tailgate on while the other was in the pass. seat . I was going through 1st-2nd-3rd gear and my uncle looked over to me, and was like ''how fast are you going'' and i responded with 80ish....He than responded with''are you kidding me? And u still have three more gears!?''....His eyes almost popped out of his head. It was great. Nothing is better thant he t56 IMO. I love it! I get asked ''wat you got in there'' and i tell them a 355ci lt1...than when i say i got the ''6spd'' they are like HOLY SHIT! So yes its well worth it, and 850 bux isnt bad for that trans.

**03blazer** · 11-23-2009, 09:27 AM

I think you'd be more than happy with a setup like llorracs93s10's. You could try and get as close as possible to his setup. 4.10 gears and a T56 are like a perfect match. You wouldn't be sorry... He's gotta be running close to 350hp at least.

pssh...i wish. I need to ugrade my fuel pump, still have the stocker and its not a sufficient enough one for this motor. It put down 250rwhp/300rwtq with it running like this. Peak power was only at 4500 rpm, so i have lots more power to use. Thats about 290hp/345tq at the crank right now how it is. Id like to be a 300rwh/360rwtq when its running like it should.

And i havent gotten the 4.10s yet, but it will be this winter they are in as well as the eaton posi.

**03blazer** · 11-23-2009, 11:41 PM

That's odd... you should be making more than that. What heads are you running? My desktop dyno pulled 350hp with a setup similar to yours...

EDIT: Just saw you said RWHP... you're probably pretty close to 300 at the crank...

stock aluminum heads. Just has the right components this time for eh cam, ad it had a high performance 3angle valve job. No porting,...which i regret.

yea 15-18% power loss equals out ot be about 287-295hp at the crank as it sits now. I would hope the extra 1000rpms my cam has for its power band should put the crank power to around 340+...which would be about 290rwhp at 15% loss.

D.Snutz · 11-24-2009, 03:27 PM

Hey, thanks for the pointers guys, I appreciate it. I'm going to leave the bottom end alone for now.

Bent the tabs on the crank pulley getting it off, so I've got to go pick up a new one. Crank snout came off last night; optispark, timing cover, chain, and gears, then the cam comes out. Then I get to cleaning, and spending some money!

D.Snutz · 01-15-2010, 12:22 PM

started pricing parts last night for the install. I didn't see a "V8 in an S10" kit for the LT1 on Summit's website...what am I missing?

Also, any suggestions for the new oil pump? I only see 3 on there, and they are WIDELY varying in price...

FYI: Tentative cost for parts, not including the installation parts (V8 in S10 kit, exhaust bits, anything else that goes on as the engine is installed): $4100

Maaso · 01-15-2010, 03:24 PM

Use the STOCK oil pump, that is the best advice I can give for anyone building any kind of engine. Just got to a local parts store and use whatever they stock for the engine. I would suggest upgrading to a one-piece drive rod for it though. Get rid of that vulnerable plastic sleeve.

And have you looked at the GM LT4 "top end" kit? It includes everything from the heads up and will run circles around that Trick Flow kit. http://www.jegs.com/i/Edelbrock/350/7109K/10002/-1

Maaso · 01-15-2010, 03:31 PM

I forgot to mention one thing too, the LT-series engine will require a 100% internally balanced rotating assembly. So anything that will require a special balancer or flywheel/flexplate will NOT work.

The LT1 uses a special balancer that is the balancer, hub, and pulley all built into one assembly. It is short and is matched to the timing cover. And the Flywheel is a "dual-mass" type. It's got extra machining around the where the input shaft slips into the end of the crank allow for the "pull" style throw-out bearing that the F-body T56 uses.

D.Snutz · 01-15-2010, 06:04 PM

Maaso, thanks for the links and info! I'll grab the oil pump at the local shop; where can I get the one piece driveshaft?

What does the LT4 top end get me? More than the supposed 430 from Trick Flow? Granted, with the TF kit, I still have to pick up the LT4 intake manifold; what else does it have the TF doesn't?

I've done a bit of reading on the internally balanced setup, but hadn't gotten far enough to pick the flywheel yet.

llorracs93s10 · 01-16-2010, 06:25 PM

go to jagsthatrun.com they have a book that has the lt1 swap in it. Doesnt have all the info needed, but has a decent amount.

for my swap, i used 2.8 motor mounts from them, vette radiator from them, sanderson headers from them, kept the steering shaft in its original spot, notched frame for ac compressor. other than that, pretty straight forward man.

D.Snutz · 01-19-2010, 06:47 PM

I've had the jagsthatrun book for a couple years now. Haven't read it in awhile, so that's definitely due. It's also based on the original S10, I've got a 96, so there will be some differences. I enjoyed the "minor massage" they recommend the sledge for...

Any word on the the LT4 setup would be better?

LT1's are externally balanced by the flexplate/flywheel. If you go with an internally balanced rotating assembly, but use the factory LT1 flywheel you're going to want to get the flywheel neutrally balanced.

Mechanically, there isn't much difference between putting a v8 in a 1st gen compared to doing it in a 2nd gen. Same frames/front suspensions/steering. The just look different on the outside. Also, your truck has a 4.3. If you can try to switch the frame side engine mounts to 2.8 mounts, and use the adapters for that. The 2.8 mounts are alot stronger than the 4.3 mounts for v8 swaps.

Are you still in Silverdale like your profile says or did you move? If you're still in Silverdale I have a buddy close by in Poulsbo. I go over there on the weekends. It's where my LT1 project truck is.

Also, it is possible to build a 383 LT1 and have it pass emissions, especially here in Washington. Our emissions are pretty lax.

D.Snutz · 01-20-2010, 01:39 PM

Oops. I should have updated that; I was a semi-active member long ago. I moved to Seattle in 2008; I'm now in Ravenna, north of the U District. I do still have the house over there. Sadly, emissions in King & Pierce county require at least a computer check, and I'm not sure how it'll react when I tell the state's lemming, "Sure, it's a 5.7L S10." Regardless, for cost reasons, I'm going with the stock bottom end.

I was planning on going with the summit V8 S10 conversion kit to take care of the motor mounts, but they don't have anything for the LT1. They have specific for GenIII and GenI, but nothing GenII. I haven't bothered to call them yet.

Motor mounts, flexplates, etc will be for after I get the engine put back together, but I do appreciate the input.

DROPTSBLAZE · 01-21-2010, 03:47 PM

You'll want the genI S10 conversion kit. The LT1 will use the same motor mounts and headers. It's just a small block with some 'updates'.

D.Snutz · 01-21-2010, 05:12 PM

thksdood..

any thoughts on Trick Flow versus LT4?

DROPTSBLAZE · 01-22-2010, 10:27 PM

Since you're not looking to do anything crazy with the motor I'd lean towards the LT4 stuff.

What heads are you running? My desktop dyno pulled 350hp with a setup similar to yours... EDIT: Just saw you said RWHP... you're probably pretty close to 300 at the crank...

Just has the right components this time for eh cam, ad it had a high performance 3angle valve job. No porting,...which i regret. yea 15-18% power loss equals out ot be about 287-295hp at the crank as it sits now. I would hope the extra 1000rpms my cam has for its power band should put the crank power to around 340+...which would be about 290rwhp at 15% loss.

I'm going to leave the bottom end alone for now. Bent the tabs on the crank pulley getting it off, so I've got to go pick up a new one. Crank snout came off last night; optispark, timing cover, chain, and gears, then the cam comes out. Then I get to cleaning, and spending some money!

D.Snutz Registered User Age: 30 Join Date: Sep 2005 Posts: 26 Location: Silverdale, WA User is: OffLine	Re: '96 Vette LT1 into a '96 S10 started pricing parts last night for the install. I didn't see a "V8 in an S10" kit for the LT1 on Summit's website...what am I missing? Also, any suggestions for the new oil pump? I only see 3 on there, and they are WIDELY varying in price... FYI: Tentative cost for parts, not including the installation parts (V8 in S10 kit, exhaust bits, anything else that goes on as the engine is installed): $4100

Age: 24 Join Date: Jul 2008 Posts: 225 Location: User is: OffLine	Re: '96 Vette LT1 into a '96 S10 Use the STOCK oil pump, that is the best advice I can give for anyone building any kind of engine. Just got to a local parts store and use whatever they stock for the engine. I would suggest upgrading to a one-piece drive rod for it though. Get rid of that vulnerable plastic sleeve. And have you looked at the GM LT4 "top end" kit? It includes everything from the heads up and will run circles around that Trick Flow kit. http://www.jegs.com/i/Edelbrock/350/7109K/10002/-1

Age: 24 Join Date: Jul 2008 Posts: 225 Location: User is: OffLine	Re: '96 Vette LT1 into a '96 S10 I forgot to mention one thing too, the LT-series engine will require a 100% internally balanced rotating assembly. So anything that will require a special balancer or flywheel/flexplate will NOT work. The LT1 uses a special balancer that is the balancer, hub, and pulley all built into one assembly. It is short and is matched to the timing cover. And the Flywheel is a "dual-mass" type. It's got extra machining around the where the input shaft slips into the end of the crank allow for the "pull" style throw-out bearing that the F-body T56 uses.

I'll grab the oil pump at the local shop; where can I get the one piece driveshaft? What does the LT4 top end get me? More than the supposed 430 from Trick Flow? Granted, with the TF kit, I still have to pick up the LT4 intake manifold; what else does it have the TF doesn't? I've done a bit of reading on the internally balanced setup, but hadn't gotten far enough to pick the flywheel yet.

Doesnt have all the info needed, but has a decent amount. for my swap, i used 2.8 motor mounts from them, vette radiator from them, sanderson headers from them, kept the steering shaft in its original spot, notched frame for ac compressor. other than that, pretty straight forward man.

Haven't read it in awhile, so that's definitely due. It's also based on the original S10, I've got a 96, so there will be some differences. I enjoyed the "minor massage" they recommend the sledge for... Any word on the the LT4 setup would be better?

LT1's are externally balanced by the flexplate/flywheel. If you go with an internally balanced rotating assembly, but use the factory LT1 flywheel you're going to want to get the flywheel neutrally balanced.

Mechanically, there isn't much difference between putting a v8 in a 1st gen compared to doing it in a 2nd gen. Same frames/front suspensions/steering. The just look different on the outside. Also, your truck has a 4.3. If you can try to switch the frame side engine mounts to 2.8 mounts, and use the adapters for that. The 2.8 mounts are alot stronger than the 4.3 mounts for v8 swaps. Are you still in Silverdale like your profile says or did you move? If you're still in Silverdale I have a buddy close by in Poulsbo. I go over there on the weekends. It's where my LT1 project truck is. Also, it is possible to build a 383 LT1 and have it pass emissions, especially here in Washington. Our emissions are pretty lax.

I should have updated that; I was a semi-active member long ago. I moved to Seattle in 2008; I'm now in Ravenna, north of the U District. I do still have the house over there. Sadly, emissions in King & Pierce county require at least a computer check, and I'm not sure how it'll react when I tell the state's lemming, "Sure, it's a 5.7L S10." Regardless, for cost reasons, I'm going with the stock bottom end. I was planning on going with the summit V8 S10 conversion kit to take care of the motor mounts, but they don't have anything for the LT1. They have specific for GenIII and GenI, but nothing GenII. I haven't bothered to call them yet. Motor mounts, flexplates, etc will be for after I get the engine put back together, but I do appreciate the input.
