Here's a dyno sheet from my 340/416 stroker with mildly-ported J heads and 10:1 compression, .547 lift cam. Don't have it in the car yet but I'm guessing it should be a pretty fun street car with 3.73 gears.
That's awesome for "mildly ported J's"! What exactly was done to them, do you have the post-porting specs? Combustion chamber cc's, Intake valves, etc?
