My cubes are 437. 4.17 x 4.00 |
They are Dart CNC ported heads with 227cc runners. This engine is very "developed."
The original incarnation made 673hp & 572#. 9 days on the dyno, 5 camshafts, 6 rocker arm combinations, 5 intake manifolds, 3 sets of headers, 3 carburetors, 2 days tweaking the fuel curve later ... whew ... and it now makes 731hp & 599#.
