Alright, here's the 3 cams
Are these Comp XR series cast cores?
11-772-8 - Xtreme Energy
11-773-8 - Xtreme Energy
And this Magnum cam isn't a cast core?
11-693-8 - Magnum
If I get the stronger springs would this help more around the 7000rpm through the traps. Should I spend the bucks on the TI retainers or would I be okay with the steel?
Lighter street friendly?
COMP Cams: Dual Valve Springs: 1.539" O.D. Outer, .747" I.D. Inner
Heavy, spend the 300 on the TI?
COMP Cams: Dual Valve Springs: 1.525" O.D. Outer, .730" I.D. Inner
Also should I run the Comp lifters? I read a while back when I was building my SBC that the 818 solid rollers from Comp had needle bearings that like to fall down in your pan when taking a beating and saw some guys like the Isky Red Zones that IIRC were bushed. And why would I want the .300 taller body ones?
