Thanking you David.
Yup, Barry's no dope and makes good stuff happen.
We share a love of standard bore non-stroked SO's. And 2.250 valves. I'd guess you have a little more cam than mine and your CNCs may better my Shelbys a bit. I was at 550HP.
The key is that yours should be seamless throughout the curve. My 600s (improved to 654s) were and are to this day. I went to 37 squirters and it picked-up nicely.
