Gamedog Dave's 1970 "BIG SWINGER" Build Thread
With the exhaust on, I was able to identify how noisy the rockers were.
Ended up picking up some 15 mil chromoly spacers from Bob Mazzolini Racing and threw them on in all conditions where I had some play between the Comp Cams rockers and the spacers provided in the kit.
Tightened them back down to about 1-1/2 threads showing beneath the rockers and they're nice and quiet now.
