I have been kicking around the idea of building one of those AC 427 Cobra Kit Cars.......but putting a Pontiac 455 with a 4L80E behind it. What do you guys think?

Funny, I was literally just thinking the same thing yesterday. I really luv the look of the AC Cobra but like the Pontiac motors. Unfortunately I suspect those cars respond best to very high reving small blocks. Since they are so light, I suspect traction is already a major issue. The 455 can only make things worse. I could be way off here, but that was my initial take. I'm intersted in what others have to say.

Torque issues aside, I think that your big issue will be the 4L80. Those cars have a 90 inch wheelbase. Even when they use short manual transmissions, the driveshafts end up being only about 14 inches. With a HUGE 4L80 you may not even have any room for a driveshaft. Something to consider.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
