poll: meanest sounding cam
Int 321 + Exh 336 = 657 / 4 = 164.25 - 112 LSA = 52.25 * 2 = 104.5?
BTW the cam is a Comp Cams Super Comp
Drag Race 321JR-12 Mechanical Roller Camshaft Only
Lift: .748''/.748''
Duration: 321°/336°
RPM Range: 5000-7500
I think those are the .006 numbers, you need the .050 numbers.
That right there is the meanest sounding cam I've ever heard on an LSx....
I AGREE 100% .............
How hard does that thing chop? What idle speed do you have it set at? I will be using a 257/266 on a 110 lsa and I am getting anxious. I was told it is going to chop real hard. I was thinking of an idle around 650-700 if it will stay running at that low of an idle. Thanks for the input.

yes, more overlap, more chop.
