Lets talk lifters

Put together a 396 Chevy years ago.Comp was 10 to1.Summitt cam(238/[email protected]).Fouled plugs in two days ,3 inches of vac.My boss grabbed my ear,we stuffed a set of Rhodes,bumped initial to 14(38 @3000),and installed a msd.Vacuum went to 12,nice combo.I have used them several times since.
