1972 Plymouth 340 - 4 speed - 355 gear - Carburetor Suggestions
I've got the same combo in my E-body and put a 650 AVS2 with electric choke on to replace the rebuilt Holley 650 DP. Night and day difference. Runs great with very little adjustment. Probably not perfect but for cruising it is more than sufficient. The Street Demon would probably work just as well. For the price, it wasn't worth the time messing with getting the worn Holley to run right, and it maybe never would due to shaft wear and other issues.
