Swapping? Heres A List Of Parts And Answered Questions!

[s10rcn]

so i will have to get all new guages then?

[BadAss_S10_2002]

Yes you will.

[Nightwing]

is there a place that makes blank inlays for where the stock guages go so i can cut out the spots for all new guages in the stock dash location? or what is the best way to replace your guages since aparently they will no longer work after pulling out the ECM.

Thanks
Tom

[BadAss_S10_2002]

Easiest way is to lay cardboard behind it and the area out. Then transfer that over to 1/16th sheet metal or aluminum. Then place where you want the gauges and start cutting.

I just quickly skimmed through this thread and I don't know if someone has posted this website before.

It looks like they have the goods for 94+ swap

What are the advantages and drawbacks of using a 400 than a 350? Sorry so many q's but i wanna be sure to know what i am doing before i start

if your truck is tbi just swap all the sensors over to the small block. you will need to get a distributor from a small block 87-95 tbi. also you should swap the p.r.o.m. chip( there may be 2 if there is swap both of them) from the same year truck with a 5.7l (or get a performance chip) as for the throttle body its self its identicle to the 5.7l with the exeption of the injectors. you can just buy 5.7l injectors for a truck or holly sells a 670cfm direct replacment(plug in) for $340

also cfm-tech sells tbi power accesories and a ported high flow stock gm throttle body for $230

what happened to the old school. i have an 85 s10, wanting to do a v8 conversion. i need to know some info about the rear end, one guy told me on the mys10 forum that i would need to swap the rear end and told me to put one in out of an old camaro, or by a new currey or something spellin pry aint right, then he said if i was short on funds make sure my rearend was one from the later 4.3 models cuz they are stronger or somethin. mine had a 2.8 and a 4 speed. the motor i've been thinkin about is the GM deluxe 350 ho crate motor. and a 700R4 tranny. help!

Also, all I'd have to do is change the PROM for a full sized truck application with a 5.7/auto, right?
Thanks

Anyone? I might be doing same thing but 92 4.3 auto to 350. Wondering about trans locations and shorter driveshaft? I have a long bed if it matters.

[boonman]

I just got done swapping a 350 in place of the 4.3 in my '91 S-10 Tahoe 4x4. 2 days ago as a matter of fact. I however went carb. I didn't want to do a fuel injected motor. I don't like them. Anyways, I left my trany in the stock location, (700R4), and bolted the new motor to the tranny. I then measured up for my mounts, and made those. I bolted in the mounts, and all was well. I bought an oil pan from advance adapters, (because of the front end clearance issues with the 4wd, and I also got some of their slick fit headers. i was less than impressed with the parts. Whole swap took me 2 weeks. I had hoped to have it done in a weekend, but motor problems forced other arrangements. Here are some pics.

Here is the pass. side motor mounting area

And the driver side.... (turn monitor 90 deg. counter clockwise to view..)

[Beeker]

Looks good dude. Let us know when everything is back together and running. Im currently taking mine out, and doin a small rebuild on it.. maybe setup for a HEMI.. I dunno yet

I am doing a 4.3 to 5.7 tbi swap right now. i'm keeping it tbi because of emissions and carberated is nothing more than a regulated fuel leak. i'm leaving the tranny, t-case, driveshafts in the stock location. you can move them back if you want but i have 4x4(too much shit ot modify). i am going to modify my radiator support instead to hold 2 14" permacool high performance fans.
I have heard of people using the 4.3 prom/tbi, but i'm going to get a prom chip out of a truck with a 350. also i am using the 4.3 throttle body so i am buying 5.7 injectors for it(the 4.3 and 5.7 tbi's are identical accept for the injectors). I am going to weld up my own oil pan. I am also using all the accessories off of the 4.3. I will hopfully be done soon and have some pics.

Well, a TBI unit is nothing more than a electronically regulated carb. I am glad i do not have to worry about emissions here in Buffalo. My truck doesn't even have any catalytic convertors. You have to regulate the fuel somehow, and what simpler way to do it than with a carb. I like carbs because I don't need to chhange the computer to change the way it runs.... I know you don't need a computer on everything, but a TBI only flows so much fuel.... :headbang:

[CleanCutDesigns]

I have to pass emmissions too. TBI 350 will pass right? As long as it was a 4.3? Also 350*sBlazer, what are you doing to the trans to beef it up? Exhaust?

[CleanCutDesigns]

One more thing, 350*s-blazer were/what did you get your 350 out of?

[tomskifi]

IF you want to see nice swap ck LS1!!!1 just finished all street legal pass inspection almost daily driver or ck old caddy hasLS1 ,turbo ++++++ more .both are fo sale

ohh i was just fauqing around some guy i work with said and it sounded funny. i was going to go carbed untill i found out about az emmission laws/ and how easy it is to keep tbi.
if you have the money you can get some flow out of tbi(for ex. the holly tbi 9000 commander, edelbrock mpfi manifold that plugs into existing tbi wiring)but it is expensive

here in az you have to use a engine as new as the vehicle or newer. I think you just have to run as clean as a 4.3. but that shouldn't be hard it is only tbi. you can use the 700-r4 that is on your 4.3 the jtr manuel suggests you modify it for correct shift points(i'm not a tranny expert but i think all you would need is a governer) . I have heard of people useing them and not modifying them and they ran fine. I'm just going to rebuild mine because it was screwed up before i got my s-blazer(wouldn't shift out of 2nd) i got a stock overhaul kit from kds performance with the corvette servo and the .500" boost valve for $140.if youwant to beef up you 700r4 even more go to kdsperformance.com they have lots of stuff there, you can get a better rebuild kit and a shift kit. I got mine from a junk yard( it was missing all accesories, distibutor, and dip stick, ohh and a few intake bolts too). I think it came from a truck?I do know it is a 93' though. i got a rebuild kit and a crank( because there were some grooves in the main and rod bearings and on the jornals. but the cylinder wall had almost no wear.)I got sealed power cast pistons,perfect circle rings, cleavite rod and mains, durabond cam bearings, and felpro gaskets in my kit with a timing set and a stock cam for $300. and i just orderd a cam about an hour ago( a comp cams extreme energy part # cca- 12-249-4. it is suppost to work with tbi and my computer. i am going with dual exaust 2 high flow cats and 2 flow masters. and i am going to use the 82-92 low performance camero exaust manifolds, i have heard of clearence problems and heat problems with headers, and also i don't feel like pulling $280 out of my ass when i can get almost as good performance for $45.

''What's the difference between the 700R4 and the TH350?''

700R4 is a computer module controled, 4 spd with OD tranny
350TH is a 4 speed tranny, vaccum controled.

At least thats what I think the difference is, please correct me if i am wrong.

700-r4 is a 4 speed overdrive with converter lock up and a th-350 is a 3 speed non overdrive. the 700r4(4l60) is controled by tv cable and hydraulic governer just as the 350. the 700-r4e(4l60e) is electronicly controlled by the computer. notice the e stands for electronic. ohh and in case you wondering the 4l60e is the same as the 700r4 ecept it is electronicly controlled.

[Nates98s-10]

Hey i just did a search on the radiator and i didnt see what year of vette radiator is commonly used, my friend is about to do a 383 swap and he needs to know, he was thinking about one from a 93 vette, sound right?

[carfanatic]

Is there any way that you can swap in an 5.7L LS-1 Corvette engine?

[ZAK]

I have a 95 s10 4.3 tbi. Can i put a 5.7 tbi out of the same year with out wiring changes??

Don't know if anyone replied to this or not, but here goes... The guy that told you all that is full of it. ALL those rearends are the same. You can run a stock 4banger s10 rear end if you wanted to. If you are going to make some SERIOUS ponies, then you might want to upgrade the ring and pinion with an aftermarket set designed for large torque applications. Unless you are dropping it at about 5000 rpm or trying to do reverse burnouts, you should have no worries. If me and my buddy can beat the piss outta one with a whipple chaged fuel injected 350 pushing a little over 420HP, backed with a 4.3L's 5-speed tranny, I'm sure it'll hold.

[Lingenfelter]

yup

[calgaryss]

Nope.


Keep in mind that there are 26 AND 28 spline rearends around.

The 28 spline units are quite a bit tougher.

[calgaryss]

Here is a link to some knowlegable responses to a similar question.

Not sure about the 93s but I know radiators from the 84-89 vette work. You can try the Genuine Corvette Radiator. I bought the Stealth Conversions Radiator just because it's a little cheaper. According the v8s10.com, they both cool the same.

[10sec96]

I've been running the stock 7.5 10 bolt in my truck for about 3 years now with only a mini spool and haven't had the first problem out of it. My truck has gone 10.49 @ 126mph with a 1.48 60 ft so they will hold up.

[chaase]

Got allot of questions for you.Would be easier to talk over the phone but here goes.

I have a 97 S10 that I am wanting to install an ls1 into.

I have the ls1 and everything need to make it run. So no need there.

This truck will not see the street.(ok maybe on occasion)So no need for ac,or smog junk.

If I can get all the info together and find out where to get some items this truck will be a prostreet/back halfed truck.

What type of radiator to use?

Anyone make tubular a arms? Tubular k members?

4 link coil over system with ford 9" specifically for the s10? I will get the axles and gears myself.

Who makes a full cage?Including the x brace through the back window? I could just have one made but if someone prefabs them would be easier.

Is there enough room when ls1 is installed for a set of long tubes? If so who makes them?If custom where?

Fiberglass front end clip? I would like one that is complete. Just hinged front end.

Fiberglass bed?

I know where to get the tub kits and could have my body shop make some for the fiberglass bed.

I guess I will stop there for now. Hopefully I will get some answers and not any flaming.lol If anyone wants/needs credentials just pm me.

I am really just wanting as much info as I can find out to pass on to the builder. And trying to help him in any way possible. And to see if this will be feasible. I dont want to put my 408 in a vehicle and have to suffocate it with log exhaust manifolds.lol.


TIA

Chris

[sonomakid94]

i want to use my 94 4.3 harness for an older motor. how do i wire certain sensors and what not to the older motor like the air to fule is that in the tbi unit? what about the other misalaneous sensors no one thinks about? i am puttin my tbi on the carb manifold by the way? i need help ne one please help me out

[Dropzone808]

i have many questions to ask but this one will stay short, im going from my 2.2 fuel injected to a 350 carb., will that make a difference and if it does, what else would i have to do??

305
327
350
400

Now I know you can bore out and everything, but anything it that range will fit with no modification to the firewall.

OK, I read the info posted, but I have a carbed 350 4 bolt chevy engine that I want to swap into my '85 S-10 Blazer 4x4 with carbed 2.8L. What parts do I need, keep and remove? And will the jtr conversion manual work for this application? or is there a better one?

Rodster

[SickCustoms]

Here's one question I don't think anyone asked yet.

Here goes: Are there any 5 speed trannys that will bolt up to s10 shifter locations.

and are any modifications that need to be made to the tranny crossmember?

By the way I have a 98 2wd 2.2

[SSVortec]

ok, i'm sure its been asked but i am new to the V8 thing, i went to the local performance shop and the guy told me that i have three options with my V6,
1. NOS
2. Blower
3. V8

so i deceided that i would be happier with a V8. so i guess this would be the place to go to ask questions about it . now, i wanted to go with a 400, i mean anything worth doing, is worth doign right . so heres what i have now. a 2001 4.3L with the "AUTO 4 SPD, HMD, 4L60-E, ELECTRONIC" (RPO Translation). now being that i am on a budget, would i need to swap the tranny or can i keep it? i know i can get a harness built for my stock gagues, but is there a way to use say a Corvette Gauge face in place of my stock one? also, woudl it be better to get a used engine (i.e. junkyard, buddy) or new crate? and where would one go to get one that would be in good shape? thats all for now, hope you this isnt too long thanks!

[anreynol]

The 454 we put in my truck required NO firewall hacking whatsoever. All we did was flatten the lip in the transmission valley so it would sit flush.

[MrDiameter]

so a 350 wont bolt up to a 5 speed on a 98 2.2l ?

[n_v_my_noma]

My best friends step dad owns a body shop..therefore i have access to VERY cheap cars i.e. totalled cars..but I can get them with the rear or the side all f**ked up and still a GREAT engine..do you think this would be the most cost affective way..I just saw a 96 impala SS with the vette engine go for like 600 bucks..and it was rolled but the entire engine bay and everything was PERFECT..so what do yall think? this be cheaper then buying a crate engine and doin it the other way? or will I still need to buy a bunch of parts?

[350*s-blazer]

you will still need some parts but that is a hell of a deal as long as it runs stong and doesn't have a ton of miles. just pull every ting out of the car though: engine, tranny, computer wiring harness,...ect.

[sic ones]

Im fixing to bring home an 88 S-10 4x4 5-speed that used to have a 4.3, but the previous owner was halfway through swapping a carbureted small block in. The exhaust manifolds and motor mounts are already installed.

Do I have to get a special flywheel or clutch?

It has no throttle. What do yall do for throttles?

And last but not least, what do I do about the fuel delivery system?

Thanks!

[bdropped]

I have a 98' 2wd 2.2l w/ auto tranny i also have a 4.3 and 700r4 electonic tranny so instead of go v8 i just want to go v6 the thing i am wanting to know it what would be the best way to do this. the 4.3 was in a early 90's blazer i pulled every thing wrirng and computer. should i use the 700r4 or can i use the tranny that is in the truck?

[bdropped]

oh yeah what about wiring?

[primus]

ok.......... i did the swap form a 2.8l to a 305 in my 86 jimmy i was 18 years old and had pretty much no experience with engines. its really easy nto rocket science and if you want to do it buy the JTR manual (lifesaver)

[Joedirt3]

u people really don't know whut your talking about. at least the guy who started this thread. forgot a couple engines there buddy....both stock ones and the 8's. also the headers don't work with the 'maro 5-speed and AREN"T easier then the manifols to change plugs, the stock manifolds work u just need TBI ones and move the steering colom over also the headers need more firewall mods, and theres more small u needa do. it's not just a take old engine out shove new one in and thats it, theres mroe to it. also it's more specific to each set up people have. also wit the jtr book, or bible as people call it, u have to still figure out so it doesn't tell u evreything. if u guys wants actually good info go to s-series.org. i tried them after this site and saw whut are on the net. :thumbup:

[joshslilbabigrl0]

I like the beeker guy for ur icon.

[LaynLo]

curiosity is killing me so i have to ask a few questions.

i have a 90 tbi 4.3 blazer 4x4. from what i have read and have been told i can swap in an 89-93 tbi 350 with little modification to the wiring harness.

since its a 4x4 will i need a new oil pan? also i was told i would need a new "chip" for the computer. i'm still not to sure what that is so what is it?

i almost forgot, can i use all the accessory mounting stuff off the front of my 4.3 on the 350?

[350*s-blazer]

you will need a oil pan check out jtr they have one for $200 sheapest i have found
www.jagsthatrun.com
you will need to get a prom ship from a junk yard or buy a performance chip
and you can use the 4.3's accesories on the small block, thats what i did.
you can buy headers for around $280 that are a very tight fit or you can get camero manifolds for $50 fit nicely.
