3/4 cam
Rabbit, I got one hanging on the wall in my store and you saw it.
Guys I see a lot of problems with flat tappet cams today , I have 1.3 rockers and use the extra and still lose cam lobes from 3-4 diff companies and I THINK the problem is lifters , only people use them today are hot rodders and street rodders.
we build some 305 sprint mtrs where we can only use these lifters and it is a mess. Later J.Smith 4621 racing
