I own a 40 Chevy with a GMC 302 Inline 6 running a mild cam.
I am interested in using hi lift rocker arms, or high lift roller rocker arms
Anyone know of a source?
Anyone ever tried to make them from scratch?
Any other engines with roller rockers adaptable to the GMC?
Anyone ever tried to increase the stock rocker ratio by welding on
added length?
