billet Roller cam Spring selection

[buickboy]

Need some experienced help here. Have not picked the billet roller cam grind or duration yet but need to tell my machine shop which springs, retainers, locks Etc for 11/32 stemmed valves on Champion Irons. Know virtually nothing about which cam manufacturer/vendor is best either. Learn me!!

Your limited to comp 941/K motion 750 unless you go with a conical spring. In that case 26918 will be good. Both will rev to 6000. Keep the lift under .550. If you want more you will need to modify the heads extensively to seat the springs. Post your goals so we can rec. If you are thinking 10.50 or slower id rec a 206/206 with .500 lift. The other needed parts will depend on the spring and installed height. Ive posted plenty on the topic lately.

I agree with Bison on the comp 941-12 springs.

Comp cams #750-12 for the retainers

Comp cams #611-12 for the locks

Valve spring shims. Comp cams #4753

Set the spring hight to 1.750
