Im trying to figure out what to do so I figured I would start here.

I have a new, never built, pre World 4.500 Hemi block. I don’t know if I should build a street friendly 528ci or try and find a 4.250 water block and build a 472ci. It’s going into a 1968 Super Stock Barracuda clone that will be street driven. I’m looking to make 550hp so do I build a siamese bore engine and hope I can keep it cool or trade it to somebody with a new water block and not worrie about over heating it?

....there is nothing like driving my 1968 Hemi Dart around town and having people looking at you like you're nuts!!
