Factory short block at 9-9.5 will make 450. Just what do you consider good power?

Thats not bad at all. Just in general, most SBM stuff is lower compression. Compression always helps. Im a newb with Magnum motors. Thought they were pretty low compression, hence alot of people run the .028 headgaskets.
