Hey Brad. I run a standard Offie 360 with two AFB Comp.750 carbs.
Have a brian fade on jets...I'll let you know. They will change (most likeky)
for the 505. I am going to do some pulls on dyno with it. My Wenzler kept my carbs loading up at idle...due to carb angle I'm sure. Intake didn't impress me on 462, maybe 505 will be different story..I will work with that to on dyno if I have time.
Estimated power is (by calculators) is 525 RWHP...
I'll check my log book for jets.
What rod springs are you using, what's your idle vaccum ??
