When I lived in Ca in the late '70 early '80 we were into the jet boats. Mine had a 455 Olds in it but the Chevy guys couldn't get enough big blocks to work with. I imagine it's different now with all the aluminum blocks and such, but the internals are still the same. You think a car with a big block is a kick, try some of those jet boats with blowers, turbos, jet stacks....etc...them suckers fly...
