I don't think the 301 is a big block Pontiac motor. It is a tiny little thing. I think is is common with the 265 Pontiac motor.

Also, I have seen pictures of the 1981 TA with the 305 Chevy motor with the battery on the same side as my 4.9 turbo (driver side (stock pictures), but all good information for me to look out for.

Any other input? Has anyone else done a similar swap? There are very few Turbo Trans Ams with stock 4.9 turbo motors. Most people swap. I'm assuming the 350 Chevy is a common swap.
