carb size for 512 stroker?

Have a break between dyno runs.

Actual OOTB Stealth head flows as we tested them.

.100..........66 cfm
.200.........142
.300.........205
.400.........240
.500.........255
.600.........267
.700.........268

Best OOTB Stealth head I ever tested.

.100..........73
.200.........151
.300.........214
.400.........245
.500.........262
.600.........276
.700.........281

They generally run like the first set of flow numbers.

Should he get other heads? If your goals are no more than 750 HP or so, the Stealth heads can be made to go there with porting and bigger valves for less money than buying other heads and having them ported into that horsepower range. I say that because no OOTB aftermarket aluminum head can go 750 HP without them being ported also.

Back to work........
