Buying a crate 3.4 next month. A couple questions

Well, I just got a new job that puts me in a position to where I have less time on my hands than usual. However, it puts a lot more money in my pocket, so instead of rebuilding this 3.4 I have, I am going to buy me a crate motor so I can put it in the truck in just a few days and be up and going. I have a question or two, and also add to this list if you can think of anything else.

1. I need to get a flexplate from a 87 or newer motor
2. I am converting over to a serpentine setup from the vee setup on the 84 motor. I am going to need a newer 87+ oil pan as well correct?
3. I'll need an electric fuel pump (I already have). Does anybody have a picture of their fuel pump install? Which lines are which on the 84? If I remember correctly, are the lines not differently located on the EFI trucks than the older carbed trucks? I mean like which size line is the the pickup, and which is the return line?


Am I forgetting anything?

Also, I have a disassembled 3.4 for sale. Nothing internally wrong as near as I can tell. I'll sell it for a $100 bill as long as you are comfortable with the freight charges or picking it up in McCalla, Alabama, which is inbetween Birmingham and Tuscaloosa. PM me if you are interested in it. I'll put it on ya! SInce it is disassembled, I could potentially freight the block, and ship the cam, pistons and assorted parts through UPS which might be cheaper.

Oh yeah! ROLL TIDE!!!!!!!!!

Re: Buying a crate 3.4 next month. A couple questions

if you are using a gm crate motor use the flywheel that comes with the motor ,you will need a timing cover from a 87 newer rwd motor as well as the water pump if your going to a single belt .the oil pan that comes with the crate motor is for a 2wd if you have a 4wd it will need to be changed to a 4wd oil pan .i just done this swap and it was fairly easy 3.4 is a great engine

Re: Buying a crate 3.4 next month. A couple questions

Yeah, I forgot to mention, I already have the front cover. I bought it a couple of years ago from another forum member.

That is cool! The motor comes with the flexplate (auto)?

The truck is 2wd, but won't I have to use the new model oilpan to work with the newer model front cover, or are the pans the same?

I plan on using the F body water pump I have lying around to go on the motor since I have an electric fan setup on the truck.

Re: Buying a crate 3.4 next month. A couple questions

Yes, you have to use the newer oil pan as well, since the front flange is different between old and new front covers/oil pans.

Re: Buying a crate 3.4 next month. A couple questions

the crate engine comes with the f body cover so all you need is the f body style water pump use the pan that comes with the engine since you are putting it in a 2wd .

Re: Buying a crate 3.4 next month. A couple questions

Well kick ass! I was about to go wrangle a flexplate from a junkyard donor.

I'm confused though now....The crate engine comes with the F-body front cover? If this is supposed to be a drop in for 82-85 and that was the case, you would have a problem using the F-body reverse flow front cover with the non-reverse water pump that came off of the 2.8 right?

Re: Buying a crate 3.4 next month. A couple questions

The front cover is the same, or nearly the same between the late model RWD 2.8 and the 3.4, both have reverse rotation water pumps. Note these are not "reverse flow" engines. The coolant still flows in the same direction, just the water pump rotates in reverse compared to the older water pumps.

Re: Buying a crate 3.4 next month. A couple questions

See, that's what I mean. If the 3.4 is similar to the 87+ front cover, then the oil pan that comes with the 3.4 is not going to work with the F-body or later model S-10 front cover....right? To make this work, I'll need an oil pan from a 87+ 2.8 truck, and a cover from the same.

The poster earlier says the crate engine comes with the F-body front cover...If it does, then it would have the reverse swirls in the cover...which doesn't jive with the 82-85 water pump that is supposed to work with that cover. Does the crate engine have an F body or late model S-10 style cover (as in fits like F body), but has swirls in the housing like the 82-85? If that's the case, it's not going to work with the F-body water pump.....or am I just nutz?

Re: Buying a crate 3.4 next month. A couple questions

if you use the f body cover that comes with the engine you have to use a f body water pump from a 93-95 because the water outlet for your bottom radiator hose will be on the oppisite side .you can see what i,m saying when you get your engine .if you have any more ?'s give me a yell thanks

Re: Buying a crate 3.4 next month. A couple questions

The pics I have seen shows a flexplate/flywheel(not sure which from what I've seen)included. The pics also show an F-Body front cover, and I did not see any timing tab, so how the hell do they expect you to drop it into the 82-85 trucks?
After seeing the price I'm glad I got the deal I got!

The timing cover included on the 3.4 is designed for pre-85' applications with "V" belt driven water pump

Re: Buying a crate 3.4 next month. A couple questions

Makes me wonder what I am really getting! So what is going here basically is the front cover is actually a hybrid cover, meaning that it fits like an 82-86, but has the swirls of a 87+ or an F-body? I think we're overthinking it here. I think what it is in reality is an old school 82-86 pan mated to an old school 82-86 regular swirl pattern, regular flanged front cover, since the truck is supposed to be for vee belts, it would have to use that cover with that swirl pattern for the regular rotation water pump, or the truck will run hot.

That being said, I think that means since I am going to a serp system that I need to use my 87+ S10 front cover along with an 87+ oil pan from an S10.....

Correct me if I am in error.

Re: Buying a crate 3.4 next month. A couple questions

I'm not real happy with what a new oil pan costs. I might go get one from the junkyard because I'm a cheapass. I noticed that possibly an 87+ -92? Camaro is also the same as the truck? The local pull a part has the price set at $16 and change for a stock pan vs $70 and up at the parts house for an aftermarket pan that might not fit right. Any input on that?

Re: Buying a crate 3.4 next month. A couple questions

Just buy a new pan, don't screw around with a used pan that may leak in a year or two, because it's already getting crusty.

I bought a new pan for my Franken60 build a few years ago, and it was worth it.

It was on the truck for over 2 years, before I decided to take the truck apart. I still have that pan, and other than the couple modifications I made to it for the turbo oil drain back and crank trigger clearancing still looks practically new. I know if I tried to use a used oil pan, that came with the engine I built I would have had problems.

What I am afraid of is a crappy fitting aftermarket pan and I don't want chrome, because that is guaranteed to leak. Do you know if your pan was an aftermarket or factory?

Re: Buying a crate 3.4 next month. A couple questions

It was bought through a GM dealer, but not sure if it was a GM OEM pan or an aftermarket replacement. I've never seen a chrome pan for the 2.8, so I don't think you need to worry about that.

I still have mine, if you don't mind the modifications I have done to it, I can sell it to you.

Re: Buying a crate 3.4 next month. A couple questions

Well, I can get a new one for about $65-70 shipped about that close thereabouts. Make me an offer I can't refuse. It is for the 87+ model right?

Re: Buying a crate 3.4 next month. A couple questions

I'm beginning to think that the front cover is actually a 87+ FIT, but with a swirl pattern like an 82-85, so my 87+ should actually fit the pan that comes with the motor....right?

By that I mean, the 87+ front cover I have, with the pan that comes with the 3.4.

Re: Buying a crate 3.4 next month. A couple questions

I think the deal is that the front cover changed in 86 to a better front design to seal better. The cover retained the standard flow pattern because it still used belts that turned in the same direction even though one belt was ribbed. The oil pan changed as a result of this too obviously. Therefore, according to what I think, the 86-93 trucks used the same oil pans, but a different front cover for 86 and 87-93 (reverse flow pattern). The crate engine is for 82-85 carbed applications with standard flow direction, therefore it uses the 86 front cover because it uses the 2nd design oil pan....the only one compatible with that flow direction and mating surface.

This may ask you why 86 isn't included in the 3.4 replacement even though it uses the standard flow direction....simple...it's fuel injected.

I hope that not only helps, but is correct

Re: Buying a crate 3.4 next month. A couple questions

Funny! Technically that pan on ebay should fit the 86 too since the 86 supposedly incorporated the new style "fit" and required a front cover that "fit" like an 87 and newer. The only difference between the 86 and 87 should be in the front cover (flow), but the pan flanges should be the same. I think the reason the crate engine states that front cover is only for the crate engine is that the 86 is fuel injected. Who is confused as hell now? Looks like we need to verify this and make it a STICKY!!

Can anybody find out if the GM crate engine front cover and the 86 S10 carry the same part number?

I just have to disconnect the exhaust now, and she's ready to pull. I just ran out of steam and had to call it a night.

Anybody have a picture of their serp setup? This truck was equipped with vees, and I am converting to a serpentine now. I have the accessories, and have had them for about 3 years...Thing is, I don't remember how they all fit up.

Thanks!!

Re: Buying a crate 3.4 next month. A couple questions

Was your front end already removed or did you do that to make the removal/install easier?

I am following your thread close as I am on the point of replacing my aging 2.8 and I see how easy access is with the nose cone removed.

My body is in top shape and I an seriouslly considering tracking down a 3.4 rather than rebuilding a 2.8. Gonna do it - make it worthwhile.

Re: Buying a crate 3.4 next month. A couple questions

I just took the core support out to make it LOTS easier to remove. Some folks say it's more work, but if you are doing it by yourself, you will appreciate the extra room to move.

My truck is in better than average shape for its age although the paint looks like ass. The main reason is....I just like this truck! I'd rather drive it than any vehicle I ever owned.

Well, I looked through the serpentine stuff. I have a TON of brackets that are making me go "hmmmm....where the fork does this go?" I do have the smog pump, but I don't think I am going to use it since all that stuff is bypassed or is pinched off anyhow. I didn't know whether you could make it work without it, but I see you did no prob, so that's the way I'm doing it.

Do tell....what happened?

Ya, I just welded the A.I.R. passage shut on the exhaust manifold, easy enough. I did leave the A.I.R. actuater plugged in so the ECM still got a refrence voltage if that's how it works, I have no true clue, hell it may just be a + - plug, never cared to check, LOL!

It's the A/C delete pulley they sell you for a 2.8, thing is it wont fit, it works on a 4.3 and small blocks, but the 2.8, so I fabed up some support brackets so it would work.

Re: Buying a crate 3.4 next month. A couple questions

You don't need an "A/C delete pulley" on a 2.8 anyway, if it didn't have A/C there wasn't anything there.

The belt will go from the power steering pulley to the alternator just fine.

If anything, swap out that idler pulley above the water pump for an "inside" pulley.

Re: Buying a crate 3.4 next month. A couple questions

Never thought of that Raven, although I spent like $20 on that new 86inch belt so.......unless it goes bad I will probably just leave it the way it is. When I did the swap originally I wanted to be able to just reuse the belt, so I never thought about what you said.
BTW, they sell that same pulley for an LT1, thing is, it wont fit it either, on our race car here at school we swapped it out and the pulley bracket would not fit, so I guess it's a universal piece that the parts stores sell. Who knows!

Yep, that had me scratching my head too. I've never owned a non A/C S-10, so I didn't know. In fact, you don't see too many of them in the south...it's just too damn hot in the summertime. Even the base trucks usually have A/C. Vinyl, humidity and 90+ degree temps don't mix well.

I'm planning on redoing my A/C with totally new parts...I mean everything except the ductwork and the dash control (hmm. maybe I'll do that too). Not only does it have to be reliable, it has to be cool since my wife may have to drive it from time to time because it will be our third "shared" vehicle for when we need one. Trust me, she don't like driving that 5spd 4.3 01. It's kind of a bastard to drive.

That being said, the next thing I need is some pictures of some brackets on an A/C equipped truck...and some advice on getting all that filth out of the engine compartment without spending two weeks scrubbing it with a frickin toothbrush.
