Crate motor vs. rebuilding DZ 302...?

[markjohnson]

If you put that Bill Mitchell 454 CID small block in that car, you will forget all about that 302! Personally, I think I would opt for the 427 CID version. A little thicker cylinder walls and it's such a magic number to so many people. It's hard to believe but the 454 Bill Mitchell small block has the same bore and stroke as a 454 big block. He even had to come up with a special head gasket. Another great engine you should look into that's priced lower is the GM Performance Parts ZZ383. It makes 425 HP and 460 FT.LBS or torque. Granted, it won't tear your head off your shoulders like one of those Bill Mitchell motors will but you could save a little bit of money to spend elsewhere.

I have considered the ZZ383 ($4700) which would certainly be cheaper.I know someone who put it in a '71 Camaro and is very happy with it.I'd have to convert the center bolt valve covers to perimeter and I don't think my LT-1 manifold will work with it either,will it?I just wonder how well these GM motors are put together compared to a specialty house like Mitchell's.The best of the best parts are in these motors.I am even considering the Motown 415 alloy head motor for around $8K.

Choices...choices.
