Dual plane to single plane track test in the works

I don’t doubt you. It’s just that I want to see what the airgap does at the track being my carb is dialed in with that intake although I know with the different heads and much bigger cam I’ll have to do some tuning. I just wanna see what kind of tuning I’ll have to do but at least it’ll be in the ballpark for the dual plane. Then I can put the M one on and go from there and see what it does.Mainly it’s for my own personal satisfaction to see what I can do with both.

remember too, the motor that air gap ran out of steam on was a stock stroke 360 with plenty of cam..260@50
I shudder to think what would happen on a 12.5 compression 418 with bigger needs
