Anybody else using this speed pro cam CS 1066R for SD 351 engine?
I am planning on using this speed pro cam CS-1066R from Northern auto parts in my 351w build. From what I have read this should work well with my SD 351w and not be as agressive as the comp cams 255 cam. Comments?
Suggestions? Oh yeah it was only 10$ extra vs the 85$ for the comp cam.
LSA = 114 60 degrees overlap. 197/209 @ .050

you get what you pay for and for the time and effort involved in doing a cam swap i would go with the comp version personally. you also need to consider replaceing the valve springs as well when doing any cam swap. do it right the first time , plus all ive heard are good things about the compcam

Comp valve springs are coming in with the cam. I chose the cam more for the step down from the comp specs than the $$. I have had an over cammed motor before and would rather be on the cautious side. First time around with speed density for me. It still has good duration so I do expect a power increase but down low where I am using this truck.
Anybody got a desktop dyno for this in a stock 91 351?
thanks, Matt
