5.9, max safe compression?
I inputted the following numbers
To determine the Scr, I figured the swept to be 748.3cc, 5cc in the eyebrows and 15.75cc in the .075 gasket, and 8.22cc for the .038 gasket, and zero in the deck. So the total chamber volumes were 83.75cc, and 76.22cc. This makes the two combos 9.935, and 10.818 Scrs
The comp cam has an ICA of 63* when in at 106
The Voodoo has an ICA of 65.58, in at 106
The comp has a very slow ramp from advertised to .050 of 50*
The Voodoo is much better at 30*
These are two completely different cams, as to performance. At .050 they are over 3 cam sizes apart; 224 vs 249
I like the voodoo in the 10.8 engine, but it may not like iron heads. It would be fine with aluminums;and should run on skunk-pee.
