CVX 20 engine swap question

[farmo83]

I have a 77 CVX 20 with the stock 460 in it. I want to repower her from 330hp to the 400-500 range but the engine hatch is very narrow and after market high flow exhaust manifolds for 460 are hard to find that would fit in my compartment. As opposed to rebuilding the 460 i've thought of dropping in a newer 502 or some other chevy that is powerful enough. Other then the motor mounts, exhaust manifolds, and bell housing what all would be involved in the swap. Has anybody ever put a chevy in one of these hulls ? Any and all advice will be appriciated. Thanks

I am running a 429 in my 77 cvx 20, and making around 400 to 450 hp with stock aluminum riser type manifolds. Could make more with larger cam. Cmon man stay with the FORD!!

From what I understand, if you have the type where the exhaust rises up from the center. they probably flow better than what I have, and I'm making plenty of power. Sure, I would get more with headers, but they arent in my budget right now. My point is, I'm sure you can significantly increase your power with what you have...although I have a BBC :D
