Cam Specs for 351W
Don:
Re: CT Emissions Max : HC 220, CO 1.20 http://www.clubcobra.com/forums/show...241#post705241 Can you help to clarify the comment by Byron regarding the cam specs for the 351W that you built along with the original CR. My technical knowledge on interpreting cam specs and the relationship the numbers have to each other regarding engine performance is extremely limited, i.e. none. Thought this subject would be of interest to others. ..........thanks Don |
Don, we are using the Comp Cams Extreme on all of our engines now. The older ones we did use Crower. Most of those were in the 280 duration. This is advertised and not at .050. The lift was generally not more than .526 and was more in the .500 range. The lobe separation was probably 108. This was a relatively mild cam with a bit of a lopey idle. I would have them run the test and see where your starting point is. Then we can address the tuning issues.
