Compression Ratio Question

demon seed said
Firstly what are the rest of the specs for that cam, maybe paste a goto for the cam card. If the cam is what I think and you are using Edel heads I'd bump the comp. ratio up to 10-10.5 to 1 for 93 octane and think seriously about going to 3.73 gears, I definetely wouldn't go below 3.55. You're definetely going with some serious internals to make a screamer so there's no sense holding it all back with cruising gears IMHO anyway.

The rest of the specs for the cam are as follows: Hydraulic Roller - 3.55-4.10 gears, 9:1 compression, headers, high performance street. RPM operating range of 1800-5800. Advertized Duration 274 in. 282 ex. , Duration @ .050 224 in. 230 ex. , Valve Lift (w/1.5 rocker) 538 in. 534 ex. , Lobe Sep. Angle 110 degrees.

I also have no problem going to a 3.73 or deeper gear.
