So im pretty good with tuning a holley, an edelbrock and somewhat a Q-jet, but ive never had a 2V before. For all intents and purposes, the engine is a stock 1971 (possibly 70) 350 2V. It runs pretty strong, good compression, no oil burning, etc etc. Points ignition, and Accell 8mm yellow wires (could be replaced, some are cracked). Stock air cleaner, with the thermac system still hooked up. When the car is cold, it idles pretty low, and unless it is 100% warmed up, its horrible to drive. Once warmed up, the idle settles out at about 1000rpm. I know thats high, but i hate waiting like 15-20 mins for it to warm up. Part throttle under any type of big load, the car kinda coughs like it swallowed its tongue and wants to die. To get over this, i have to basically punch the throttle, and it lunges forward with lots of torque and sorts itself out. Additionally, it sounds like it knocks under those part throttle conditions when the revs are below 2000 rpm (basically all the time). A little while ago, i damagd the thermac tin foil stuff, so there was a big hole in it, and extra air was getting into the air cleaner, the problem was further worsened. It seems to me its too lean, and that punching it squirts fuel in from the "pump cam" which adds enough fuel and it gets going. Its not too bad on a very hot 25*C ++ day, but when its only a few degrees colder it gets to be annoying. Basically fall and spring time in Canada. How do i tune it? If it were a holley, id rejet it, but i dont know anything about the 2V, or where to get parts, or anything. The engine is going to be swapped out soon for a BBB, but i still drive it quite a bit, and would like to solve the problem.
