This one was 4.375 bore, 4.5 eagle crank, eagle 7.1 rods, 11.1 compression CP piston, solid cam with high 270s intake and low 280s exhaust on 110. indy 1.6 rockers with .649/.595 lift. The manifold was a pain for tuning on this size engine, would have made more with a better intake for this size engine. He will have his hands full with this in a street car for sure, thanks Pete
