3.8 3rd Gen Firebird

[WH1 85]

I have an 87 firebird with the 2.8 v6. It is VERY slow. I am going to be putting in a ford 9" and rebuilding the 700r4. As well as suspension upgrades.

Question is, how hard will it be to put my spare buick 3.8 in it?
I know that it won't bolt to the tranny, but I figure that someone makes an adapter? And since our engines came in the tta's, I should be able to get exhaust, motor mounts etc.?

Has anyone done this? If it is too diffilcult I'll drop in a chev 350. But I would much prefer to put in the turbo v6.

You won't be able to fit it in without using the TTA heads, which I think were off of a fwd 3.0L Buick V6...not sure what casting number...The GN motor/heads won't fit because the strut towers in the F-body are too close together...then you need to find some TTA headers and crossover and TTA DP and the TTA motor mounts/frame brackets, etc...Way too much work unless you have a wrecked TTA for a parts car...

TTA motor used different pistons and heads than the GN motor...

Yes you will be able to fir the Gn motor into the engine bay,only without the AC.Paul at H&R parts is taking care of the motor mounts side of things to make it a drop in setup.ANd the only thing you will need to do it make a custome downpipe.Get a TH off the turbine about 12 inches Terry will sell you one. And make one from there.
