413 motorhome/truck/industrial motor "chat"

A R .... I was thinking that maybe someone has done some piston work like reverse dome or something like that. I have two sets of 30 over cast flat-top pistons but am open to other suggestions. Small cam ? ... like the 2 barrel 383 ??... there has to be something BESTer than that. I know some Chebby guys who have motorhomes and they have some new-tech grinds for their 454s. Head work? .. I have had some quick talks with a guy up here with a flow-bench. He is thinking about closing UP the intake port a little - to keep the fuel/air mixture up-to-speed at low-rpm - part throttle. I think that the intake is more important than you might imagine. My other choice is the SP2P.

T - THX for the offer but I am looking at only a spread-bore intake.

D L .... did you know that some people have suggested that THAT 413 block is just an UNDERbored 440 block ? That industrial block is a very heavy, high nickel piece.
