What would be a good lopey camshaft for a S/C'ed application? Just wondering how lopey you could go with a S/C.



*I forgot to say, for a 5.0L with around 9.1 compression."

Your not gonna find any lopey s/c cams unless you plan on spinnin that 5.0 way high, like 7k ish because forced induction cams generally have reduced intake duration and a wider lsa to help build build boost. You wobn't find a good street s/c cam that will lope alot

I know you cant have a hard lope with a S/C because if you do youll just blow your boot thru the exhaust valve. Thats why higher lobe seperation numbers are good. But Ill find somthin.

MD's has a good lobe to it. Just do what he did and use NA cams but run 10psi so that way you are only actually running 7 to 8 psi. Sounds good.

this cam has a real lopey sound power is great..but don't buy it for that. buy a good cam to work with your combo!
