94_FlareSide_5.Slow

Hey guys, I have a '94 F150 with a tired 5.0 that has 233xxx mi on it.

I bought a flat tappet 302 block (turned out to be from a '74 Maverick)

I plan on rebuilding the block with a 274/274 duration, .485/.485 lift cam.

My question is though, how will the old bottom end work with GT40/GT40P heads?

Will the GT40 pushrods fit and is there anything else I need to be concered about? Idk if I know what I got myself into haha

Thanks!
