Yes, I put it together with a small cam . I figured I wasn't racing with it so it would be ok . I plan a head change to a set of 6x4's that has been ported and all new springs and Ferrea valves with the 1.77 exhaust and Hs/1.65 rockers and the p/rod holes have been elongated,along w'RA manifolds w/2 1/2 mandrel pipe . I'm hoping this will at least give it a bit more power . I'm sure I'll have to replace the P/rods .
