Correct tntake

What would be the best legal aluminum intake for a 350 -- 330 hp. SBC IHRA crate motor? ---- Also who grinds the best stocker cam for this engine and do the Sherman hyd. lifters have a decent life span as the Schubecks are just a little too pricey? ---- Thanks

Oh yes, -- will Shell Rotella 5 - 30 with 1 bottle of G.M. -- EOS help extend the cam & lifter life or should i do the Royal Purple 5 - 30 with a can of EOS?

I know that Bruce Parsons has run very fast using a Bullet Cam and Performance Products intake [same as Super Victor]

Don't mean to hijack, but can someone tell me why some of the stockers are running Schubecks and the huge spring pressure numbers I hear about? - I put together a sbc with .842" flat steel lifters,P55 core with .875" lobes, steel valves, that winds to 8200 rpm all day long, and only has 150 seat/400 lbs. open. Just curious what I may be missing?, and why some have gone down that path?

Thanks

Stocker cams are lift enforced, so to get the duration on these lobes, they are very squared on the nose making it hard for a lifter to follow at higher RPM's unles they have alot of open pressure on the springs

Thanks for the reply Bub, I am aware of the lift rules, I just would have thought that there must be a better way than resorting to spring pressure, and the problems that come with it.

The performance products intake seems to be quicker in the 1/4.
The GM Performance Parts intake runs good in the 1/8. I'm currently running the GM intake.
