That being said, just about anything will fit in your Bird. I've got an 87' 350 block in mine. All I had to do was get Chevy engine mounts and swap over the battery tray to the pasenger side.
If you do go with a Chevy Block, you'll need a new Trans since Pontiac and Chevy motors have a different bolt pattern to the bell housing.

first off thanks guys, i did some research and came to a concusion im going to rebuild my 400 the only bad thing is i live in california and all that smog stuff sucks. so now to the next step changing the auto for a 5 or 6 speed transmission and if i cant do that than a 4 speed will have to do. any suggestions will help thanks again
You've probably got a 400 turbo trans now....leave it alone! If you went manual, you'd have to get a new console, plus cut out for a clutch petal.
There's nothing wrong with a "Hydramatic" trans. The right H.P. will make up for a lack of highway speed. 4th gear only lets you cruise! If the 400's built right...you'll be shreding tires and not careing about the Tree at the front of the 1/4 mile!
