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



interesting differences. mine is roughly 10.25:1, 248 and .604 intake, 255 and .582 exhaust, 112. so there is a bit more cam there, especially the duration on both. and mine is 4.25 X 4.5 with 7.1 rods.

never thought about going that route with the bore and stroke though, would have been nice to have some extra cylinder wall thickness in case it was needed later.

damn nice engine though!
