Quote: Is it worth the time in advancing that cam if the duration is to wide? or should i change it out? I don't have anymore info on it then what i've listed. I thought i had the tune down pretty good from the chassis dyno. I did try different launch rpm's and shift points. I do understand that the 60' is critical and until i sort that it's gonna be slow. With a correct cam for this engine wouldn't it be ideal to have the heads flowed?
Flowing the heads would cost money that you could be putting into the cam. I would change the cam out with one that has a 106 to 108 lobe separation angle, and a duration at .050 of around 260 to 270 @ .050" lift, preferrably 260 for great mid range torque. Advance it 4 degrees if it doesn't already come that way (advance ground in)and hang on. You're converter will stall higher, you won't have to change gear or tire.
