Well the loaner carb turned out to be a severe leaker once some gas got to it so it came right back off. Then just for sh*ts and giggles I put on a Holley 650 double pumper (with the choke milled off) that I had laying around and was able to get the car up and idling and actually driving. It's a 4777-3 square bore. Was hesitant to put this on since I've heard that you can't run a mechanical-secondary carb with an automatic. It idles a lot differently than the edelbrock and seems lean. If I put both hands over the air horn and choke it, it picks up rpms. It's jetted at 67 in the primaries and 73 in the secondaries with a 6.5 power valve. It also takes a minute to catch up when opening the throttle but it's definitely NOT the same issue I was having previously. Runs smooth at tip-in and light cruising, just likea to wait a second when you hit the gas. I suppose I need to do some accelerator pump tuning to get the shot just right, but overall the carfeels a lot snappier than it did with the edelbrock 1406, even with less throttle. I was thinking if I jet it up to 69's on the primary side would that help it transition better off-idle? Right now it idles around 1000rpm but it likes 3 1/2 turns out of the idle screws, which to me again says it's jetted too lean? Am I headed in the right direction here? The motor does have a bigger cam, 233* at .050, and about .512 lift. I've lost the cam card and I can't remember the LSA. Running a built A999 trans with a shift kit and 2.93 geared 8 3/4 with 245/60/14 rear tires (25.6" diameter). I know the gear is too tall but I feel that the deeper 1st of the A999 and short tires make up for that a bit....
