1989 turbo trans am heads?
Can anybody tell me if the heads used on the 1989 turbo trans am were the the same ones used on the turbo grand prix? I know the the tgp was a 3.1 but I had read some were that pontiac used heads off of the gp the it did not say if it was turbo gp or not. Please help me since i have found 2 turbo gp in the local boan yard and would get them if they wewe the same heads as the tta! Thanks!!!!

Re: 1989 turbo trans am heads?
The 3.1 & 3.8 are completely different animals. The 3.8 is a Buick design and the 3.1 is either Pontiac or Chevy, I do not remember. The difference between a 2.8 & 3.1 & 3.4 is less...
IIRC the heads they used on the TTA were the heads from a LeSabre or a Park Ave. I would imagine other models used the same heads, like the Delta 88, 98, and the Pontiac Bonneville from circa 1989...
BTW, GRAB THOSE SEATS, I think they are the same as the Ultima seats from the GTA in the Turbo cars...
