Congrads on the motor thats haulin the mail. Don't pay any attention to some of these guys that are jealous of how good a small block can run. Some think of small blocks as if its a chevy or ford your talking about, if u don't have a 500+ inch HEMI or big block then u don't have u know what until you come by them on the big end.

Bob goerge i though Ryan J did the heads on Mark davis demon or maybe i'm mistaken. If u can build small blocks to run mid 9's why does an all aluminum 588 hemi only run mid 9's
