NA, no blower. These engines represent about 50 years of GM big block experience with D-ports, tunnel ports, valve angles, etc. and flow very well. Probably using a set of headers tuned for top end, fair amount of cam and about 950 CFM carb. If the dirt track boys are running alcohol, that number is easy. It takes about 60-75% more alcohol per pound of air and evaporating all the liquid really cools the intake charge, making big numbers easy.
I'm sorry, 720 hp out of the box with 1090 CFM carb; http://www.chevy-crate-engine.com/572_720_chevy_crate_engine.html
