I say go with the LT1. I have had experience with both. Lt's are also the biggest PITA to work on thou.

If you take care of the LT1 and do an LT4 cam head swap or w/e it will run with the best of em. A pushrod motor is the way to go. OHC motors are to expensive to mod and unless its a 4v or 3v you dont really get gains from bolt ons.

The only issue with lt1s is the ignition. that **** blows.

I appreciate the input, but i've ridden in my buddies 97 cobra and the numbers are pretty close with the 99-04 gt's strip wise, and it seemed hella faster than this trans am, maybe it was because i was driving it and not in the passenger seat as i am in the cobra, the cobra will break loose when you punch it in first, the trans am did not. we did have 3 passengers in the car = about 700 pounds but i dont know if that should completely stop it from spinning out.

A cobra is also a 4v 4.6... not a 2v 4.6 like a gt is. Big difference.
