It was making peak HP at or under 5300 RPM, which didn't make since to me
I should have tried a bigger carb, maybe in the car later
The last pump gas 340 stroker motor I built, ( 9 second Phils Cuda W2 motor in 2002 or so) and dyno tested made 514 HP with a BG 850 CFM Speed Demon, 13 more HP with a 1050 Dominator on a adapter on the same intake
Bottom line is that I'm hoping this motor tuned well in the customers 1966 Dart GT will put a big old grin on his face at WOT
