I have a few weeks off, going to back up and take another go at it.
New set of 3.90 gears, pull trans back out to fix leak and change out the front crank seal. Have a new Carter 750 AFB on the way. The current one has modified boosters which work great at WOT but cause a slight tip in lean spot with light throttle I have been unable to tune out without replacing the boosters.
Was this close to ordering an EFI unit to play with. Got the AFB for $120 shipped.
