Well the car has been finished for awhile now and most of the bugs are worked out of it. The problem I need to correct now is the engine performance. It is a 351 Cleveland 4V. Everything is new or rebuilt including the carb and distributer. The car lacks power and seems to stumble during acceleration. I put a remanufactured stock Autolite carb on it and tinkered with the settings. It has a new stock distributor, but I did not take it to the machine shop to check the curve. I set the timing at 15 degrees but runs like crap so I tune it by ear. Think the curve on the distributor is out? I am running a pentronix ignition. Any specific settings I should be looking at to get this thing running right? If I have the curve set at the machine shop, what should the settings be? Motor is all stock.
