Do you know specs of diferent cams? i've seen older 500 hp 12.7 with injection advance listed on the valve cover as 20 deg and newer ones listed as 14 (I think) are there particular cam/injector combinations that get better results than others?

If you would be willing to I would be very interested in more details on exactly how you do your cam timing adjustments.

Here I am Getting off topic, maybe we should rename this thread series 60 performance tuning. to cover mechanical modifications as well.

does anyone have experience with the low compression pistons. Is there anything that i can do diferently in the ecm than I would on a higher compression engine?

Thanks everyone!
