Greg,
Thanks for the input. I know desk top dyno is not gospel, but with the DV3E-A2A heads with stock valves, it says I should be seeing around 600 HP, maybe 625. I believe the base HP for a 8:1 460 is around 335. The porting and valve size assumptions make a BIG difference in the predicted output. I had the engine apart last winter and all of the piston to bore clearences were within spec, the bearings were also in spec., so I think the bottom end is OK. I still believe I am missing some HP from the heads or the intake manifold/carb since the charts say 5500 on the B is about 525 HP. The carb is a single 780 Vac secondary Holley. Also, the jetting may not be optimum. I have 72/90's w/PV's in prim/sec. Will that carb support 650 HP? 750 HP?
BTW, Any history on the boat? feel free to email me Thanks Tim
