If you want the same ETs you were running just stick the .585 in it.
If you want to go faster then stick the comp .650 in it.



I almost was going to suggest the exact same thing/cam.

Its big though, 290/290 @ .050 .650/.650 on a 108 LSA Better have enough vert.

Although using the Cam Dynamics cam he has is a reasonable choice if he was happy with the way the MP 0.590" ran. Here is a newer alternative to the Comp 290, 0.650".

Comp Cams MM305S-10
This is what I measured:
305º/320º@.020", 279º/287º@.050", 197º/200º@.200", 143º/143º@.300", 112º/107º@.350", 0.433"/0.420" lobe,
110 LSA (with 1.5 = 0.650/0.630)

What CR does the motor have?


The CR on my engine is 12.5:1. My converter is a Turbo Action "J" converter, should be plenty .
I just put a Comp Cams .650/.650 (the old McCandless grind, I think) in a friends 541 ci, Indy iron headed, Mega block engine. It just went a 5.96/115 (1/8)yesterday. I looked at that cam, but was thinking it was probably too much, given my unported RPM's heads. No since in subjecting the engine (valve train) to all that added strain, for no gain.
I'll take all the "schooling" that you guys will give.

Thanks,
