The Jesel and dry sump picked up power last year quite a bit. The Jones cam was another significant step up last year. This year we upgraded to the bigger bore size, the thicker block, better rings, gas ported pistons, etc. That picked the power up another 40 hp or so over last year's motor.
I have more than 100 dyno pulls on this basic combination ...
And just for comparison with these heads,
Back when Andy ran the stock block (smaller bore) with the same heads, the solid flat tappet cam that I run (Comp MM305), plain 1.5 rockers, etc.; it made right about what I think I am making:
738 hp at 6400
641 ft-lb at 5500
440 block, 4.250" stroke, 505 CID --Jim--> 400, 4.250", 511 CID
Indy EZ ported by MCH (same heads), 13.5 CR --Jim--> 440-1, 355 cfm, 368@0.800", 13.5 CR
Standard oil pan and oiling --Jim--> Moroso 8qt standard
Comp MM305S-10: 279/287 at 0.050", 0.650/0.630" lift, 110 LSA
Indy 440-2 intake with 4500 adapter --Jim--> I have run both 400-2 and 400-3
1050 Carb
2x32 headers --Jim--> 2-1/8 x 32
