.065 is pretty thin , I was worried about .113 in a non thrust spot on one cylinder and had a half fill on my D2 block with Pro Gram caps that was other wise .225 and thicker on the other cylinders

Did you have to fill the floor on the intake manifold too ?

Scott Foxwell sells some nice Promaxx FE and BBC cylinder heads, nice option when everything else is BO

I've never installed a AFR gauge just for idle but once installed you check everything and every mode, super rich or super lean will burn eyes from the unburned fuel going out the exhaust , seems like Drew just posted on FB about a carb he received that didn't have the secondary idle feed holes cut in the gasket causing a real lean condition at idle so you might just need to take apart and give the carb a good look over

Maybe the spiral gears and being new/tight caused a momentary binding situation that is now fine after more miles ? I've only built one with the Tru Tracs and it was a carry in type deal and new parts but I do see the customer frequently and never get complaints of noise

TDC is not a good timing setting for anything, set it at 15 base timing for testing

Thanks guys , I have a chance to buy my 65 Fastback that I sold in 1989 , I had it ladder/tubbed with coil overs and ran through some hard times and had to sell it , 35 years later I see a similar car in the FB market place thinking wow this brings back memories , as I kept looking it had my wheels Crager super slots (they only made them for a year)and the 7 inch snorkel hood scoop just like how I sold it , interior looked the same , it's still a roller just like I sold , so I messaged the owner and said I think that's my old car and I only have one picture of it tubbed and that's the day I sold it , so I get to work Monday and take a picture of a picture and sent it to him and he replies back that's your car !! So 4 owners later and 35 years untouched from my last time at ownership it looks like I'm getting my old car back next week and plan to stuff a FE in it and probably a tear drop hood to replace the snorkel scoop I am stoked to get this back
