So after being sold on doing a hydraulic roller from butler and comp evolution lifters. The budget has been getting pretty high and I already have a set of NOS johnson solid flat tappets with the edm oiling hole. So I'm thinking it might just be best to run a SFT cam.

I was looking at the crower 60311 and have rea don here a lot about it and a many guys suggest it is equivalent to a RAIV cam. I also contacted crower for a custom cam and they gave me one that's just a hair more. Here's the grinds


#00160M CUSTOM 400/455/460 PONTIAC SOLID FLAT....112 LSA 250/256@050".....348/.354 LOBE....522"/.531" GROSS W 1.5RR....B1317/B1318


Crower 60311
INT/EXH - Dur @ .050” Lift: 247°/252° RR: 1.5/1.5 Gross Lift: .505”/.517” LSA: 112°


My concern is would these cams want to run in a higher rpm than I really want to? I think I'm going to set my limit at 6000 and want to make sure I'll make good power off idle.
