At the end of the season I had an issue with carburation and during the process of eliminating an off idle bog, I recurved my distributor. My ignition system is mechanical, Mallory Unilite, and it was recommended I use as much initial as possible, all in at 38* by 3000rpm. The engine is a 70 LT1, 383 stroker, old school. I ended up at 20* initial at 750rpm idle, all in at 3000rpm at 38*, a steep curve. The engine really perked up on the low end, and I lost nothing on the high end. The engines in a 63 Vette street rod, with Hooker side pipes and 2.5" inserts. Needless to say, the pipes are loud. I haven't noticed any sputters and haven't heard any detonation, but still wonder if the initial is too much for the street. I pulled the plugs after a couple hundred miles and they are not fat or lean, pretty clean burn. Anyone else running a similar set up?
