Hey Guys,
I was wondering if I could get some opinions on ignition timing / carb setup for my sbc. I did not put the engine together but this is what I know about it. MSD Ignition box, MSD Dist. Edlebrock (750?) cfm RV/Performance cam (make unknown) possible over bore of .30 or .40
I say this because when I bought the car the kid told me it was .40 over but his knowledge of mechanics is very limited. Unlike my own !!
I was wondering how I can tell if the ignition box is working correctly,and what a good start point for ignition timing might be. I have read 16 and 14 BTC but the car seems to like 12 better. Also tips on tuning this old carb. Set the idle low, tune the air adjust screws rich then back off? I tried these things last night and it is running pretty good but a little rough on the low end 1500 - 2500 rpm. Above that very smooth. The exaust seems rich and burns the eyes when sitting in the car at idle. I appreciate any help. Thanks!!
