Jetting question

I have a 1050, 4500 carb I was running on a 466. It has 92 square jetting. I am now "upgrading" the rotating assembly to a 545 and am going to put the same carb on the new engine. Same car, drag race only. Do you have any suggestions on where to start with new jetting?

Second ? -- NGK 5671-9 - c16 fuel - NA - any suggestions on what gap to start with? I was thinking .035.

I would look up Holleys list number and jet it to what they recommend for starters and go from there.

92 squared is still well in the ball park. I run 90 squared in a 1250 on my 552ci but I'm a mile high. Let me say you won't hurt it at 92 squared and will have to tune from there.

Plug gap at 35 on the -9's should be fine na me thinks.

I ran 96 square on a 572, and raced in DA's around 2500 or less.
