I was reving about the same as yours ---your reading might not come as high because your throttle plates are open more(higher idle)No you dont need the vac line except the PVC--keep that hooked up that keeps your crankcase gasses clear.

Does anyone know an easy way to check to see if the camshaft is 1 tooth off (without taking the cover off?) I know the long drawn out way and its almost as easy to just take the cover off.

I hooked up the brake booster and the line to the tranny. My vac is still 11 and it doesn't kill in gear. Might be cause my idle is still a little high in gear it is at 1000 out of gear it is about 1200-1300. So I might stall if I bring it down.

Just thought I would toss this into the mix. A Lars quote from a previous backfire issue.
"Your jetting doesn't sound right, and it doesn't match the BG jetting requirement for any 750 MD carb. Your symptoms are those of a lean condition. Jet the carb to its correct stock specs and then bump it up 2 sizes if you need to in order to cure the backfire. Backfire through the carb (if timing and valve problems are not the case) is a lean condition."
I hope not to offend anyone or misuse the search feature by providing this quote.
Good luck with the new setup, I feel your pain while remembering similar challenges many years ago in my Father's dirt floor garage rebuilding engines and trannies.
