Default Carb Jet Sizing Questions
Hey folks! I just did some upgrades and was wondering where you think I should set my jet sizes.

What I had: Ford Racing 392 crate engine with Performer RPM intake making about 430hp. I have a Jet Modified stage 2 - 750DP 4150 carb with 72's in front and rear. It ran great with perfect throttle response, but perhaps a tad on the lean size according to the plugs.

What I have now: Same everything with AFR 185 heads and a Victor Jr intake. About a 80HP increase according to the articles and all that crap.

Where do you more experienced guys think I should start with the jet sizes?

Thanks!
