if you are ditching the tbi, i'd look at the Comp Cams XE274H. Guys have had a lot of good luck swapping that cam into low compression 454s.
get a good manifold, carb, cam and headers and you have a healthy motor.
trying to go any bigger than that you're gonna end up rebuilding the motor to bump up compression

This is pretty much what I was hoping to hear. A rebuild will happen later but is not in the cards right now. This car has already been sitting 3 years. I want to drive it.
Will this cam require adjustable valves or different pushrods? I thought I read the TBI heads have non adjustable valves from the factory.
