Needs shorter pushrods. Distributor gear material and cam gear material must be compatible. Ask the cam grinder to be sure what distributor gear material to use. Needs thrust button at the front of the cam. Some guys will use a cast aluminum front cover for the rigidity of it when using a thrust button. Other fellows will go the low-buck route and weld a piece of 1/8" thick steel plate into the stock front cover to prevent the thin sheet metal from "oilcanning".
