thank you guys for the input... alot has been happening i found out a few things about the car. I checked the id plate and it turned out the car was originally a firebird 400 4spd with the deluxe pkg.

I checked the block code it was a 500813 which turns out to be a 455 4bbl out of 75-76 Pontiac. The transmission looks like a 350.
I think the 75-76 had a Siginaw 4spd correct or a t10? I have yet to find out what the ratio of the rear end is but a friend mine is assuming its probably a 4.10.

Either way i've got to swap 5-6spd into this thing. My plan is to get the car back into a standard and start taking the car back to original.
