My least favorite job to do in the shop. But it’s gotta be done. Rebuilding this 750 double pumper.

351w stock car
Didn’t like the numbers we originally got from the cam we had in it. Went back to the drawing board and figured out how to get it to come back around. We’re right in the ballpark now! Testing is everything in racing! Some times it comes at an extra cost!
Thank you to Craig’s machine and dyno for the dyno time!
