red line

i think I'm going to retard the cam to get more at the bottom end and less at the top .
I am not sure this has been noticed but the above statement is backwards..... You should advance the cam timing to get more low RPM torque. I disagree on moving the cam 3 degrees... it will make a noticeable difference but not a huge one with just 3 degrees change. I don't know this cam's ground-in advance, if any, but going to an ICL of 106 or even 104 is the kind of recommendations I have read (and which make sense with any moderate compression ratio engine if you want better low RPM torque).

I also don't think the HP peak will be at 5000 RPM with this head and cam; there is 56 degrees difference in the advertised duration and the .050" lift duration... it is not a big cam. So that changes the numbers on RPM's at shift points and TC stall.
