I've been thinking of putting a 3800 SC in a chevette. I know the 3800 non-sc came in a rwd configuration for the camaro & firebird, but I don't know if it's the same block or just related. Does the 3800 SC front wheel drive L67 come with all the holes and other requirements for mounting in a longitudinal rwd configuration like the camaro/firebird? I also know the 3800 SC came in the Holden Monaro CV6 (3800 s/c GTO, basically) but I don't want to buy an engine from australia...

So I thought the 3800 swappers here would be most familiar with the block....

I would think that you could if you used the transmission from an Isuzu Trooper. There are serveral current threads that seem to have verified that the Isuzu uses the GM front wheel drive motors in Rear/All wheel drive applications. Take a look at this thread: https://www.fiero.nl/forum/Forum2/HTML/058571.html

I think it's possible to use the f-bodies 3800 with the supercharger and lower manifold from a GTP/REGAL/RIVIERA . This combo could then be bolted to the 4L60e tranny that was originally equiped in the f-bodies. You wouldn't have to worry about drilling the starter bolts, but your throttle body would be facing the rear of the car and you might run into a clearance issue with the chevettes firewall. Cool idea ,but i still like the 500 caddy motor that was swapped into a chevette!

If you're set on the 3800sc... the australian version used on a number of aussie holden models has a supercharger/throddlebody configuration that would work on a RWD config.

I won't be using Aussie parts. Not enough cash flow to justify it. However, I am now considering going with a 3800 turbo to solve the problem of the SC up against the firewall...

And I've found a couple of sites where people have successfully swapped in a 3800 from a camaro. Now all I need to be sure of is how related the 3800 camaro engine and the 3800 GTP engine actually is. Does the fwd forced induction version actually have the same block as the rwd 3800 out of the f-bodies? I need to know this fo' sho' before I plunge into this project.

All the 3800 series II blocks are the same. The SC's get different heads.

Thank you. That was the confirmation I was looking for. + to ya.

yup, all the blocks are the same. If you wanted to go turbo, Id just find one from a camaro as I believe the starters are on the wrong side for RWD app. Plus theyre cheaper. People seem to think GTP engines are gold just because they have a supercharger. Get an L36 from a camaro, then buy some L32 rods, and L67 stock pistons off of clubgp. Theyre cheap, and itll lower the compression to what you need for a turbo engine. Also, dont forget to polish those combustion chambers while the engine is apart. Itll help with KR a ton.

Maybe you want to speak to this guy about the engine he just purchased. https://www.fiero.nl/forum/Forum2/HTML/060287.html

As someone mention, the f-body 3800 blocks are the same as far as bolt holes. The problem with bolt-in is the accessory drive. The accessory mounting on the L67 won't allow the f-body motor mounts to bolt up. You can still do it by re-locating and/or deleting the A/C compressor. I think the passenger side mount is OK on the L67.

Can also do custom mounts:

Next time the engine in my S10 4*4 drops dead, I really wanna go 3800SC in it!

Lots of room to mount stuff, no A/C etc. - I think a custom pan to clear the diff would be the worst of it (and I can make one of those!).

Thanks Dan.
I know it's late, but + to you.
If you wander back in here, the chevette swap is still on.
I like those mounts!
What did you use for the bushings?
From the AC I take it that's a fwd block?
Did you keep the AC there?

From GlubGP

" The reason for the switch on the L32 as I was told was cost, they actually found a way to create the L32 rod cheaper than the old L67 and have it be stronger so it was a natural. The L32 rods have a great tensile stregth and a great finish so most people I showed them to said shot peening would be a waste. L32 Rods also use bolts that are captured to the caps so we skipped the ARP bolts after reviewing a data sheet on the stock bolts and they were more than adequate. "

I atempted a 3800 in a chevete when i was younger and a little less experianced so i never finished it. I did get the engine in the car though used a 700r4 from a mid 80's v6 f body. You have cut the trans tunnle up a little bit but nothing to bad the biggest problem i encountered was the squeez between the strut towers. Once it's in there there is enought room but it sucked getting it in there. droping one in an s-10 is a pretty simple operation. A little modding to the pan some front mounts and your ready to go. Had to tub the firewall for the TB though before i went turbo.

I'm back

The bushings came from Advance Adapters (www.advanceadapters.com). It is a FWD block and the A/C compressor stayed there.
