Cam spec knowledgeable, queston for you...
Been studying up for my planned big block build, and want to get a pretty bumpy cam, using 10.5 static comp ratio, +/_ .
I can't find a little info on something I've been interested in.
The question is on the intake closing point, what is the approx range to where it'll bleed off some low rpm compression to avoid pinging? (it's hot here in Vegas) I don't want to rattle the thing.
I know the overlap and sep angle will have limited amount in it, but have read in a couple of places where the intake lobe closing later will help with avoiding pinging on the street, is it a big difference? Or is it just the wrong cam for application?
What would be the numbers to look for on specs for bleeding a little low speed off if I'm pushing the limits on static comp ratio for street?
Or is it a non issue if the duration is on the longish side?
My build would be:
540ci, std deck height
10.5 static comp ratio, no Nitrous, no blower, etc.
RPM range to 6000 +/- maybe 6500 max.
Must be pump gas 91 octane slop.
I'd like to have 600 h.p. at flywheel, which I feel for the h.p/c.i. ratio is realistic with pump gas, but I don't know for sure.
Any thoughts? I'd like to hear them.
