I can tell you this cam works pretty good in a mild 340. 10:1, RHS heads, Victor, Fast EFI, mild converter, 3.91 gears, 315 MT DR, full exhaust, 3250+ lbs and goes 11.40's @ 117 shifting at 5000. Yes, 5000. Very street friendly cam IMO.
When I was running a 360 street car with 3.23's and an XE268, COMP recommended a 20-228-4 lobe as an upgrade for a more strip setup with 4.10s and a 3-4k converter. Duration @ .050 241/247 Lift is .545/.545 with a 110 LSA.
Never got the chance to run it before I hurt the motor/trans and went to the dark side (RB)
Make a call to a cam guy, or run what ya got and call it good enough.
