A different type of intake system with engine management would get him over that 475 horsepower C.I.S hump
I got that quote from an article in my local PCA mag

with CIS you can see some serious hp.. with the mods you listed you will probably see over 350hp easily

Try SC sport cams, coupled with opened up ports.

you may want to open the dia of the cis manifold ( perhaps extrude hone it) and the phenolic blocks cant be opened that much, so get a set of aluminum blocks... with the intake pathe free of restrictions and a good cam the power will be there.
