My 1981 Ramcharger (6800lb) has a la360 in it with a performer dual plane intake with a one inch open spacer, stock exhaust manifolds, EZ-EFI 1.0, using a streetfire CDI box and automatic 727 transmission. Ignition timing is 12 degrees btdc, there is about 15 degrees of mechanical advance and the vacuum pulls in 10 degrees. All the vacuum lines are brand new and I've hunted down the last tiny leak. idle is 650 Current AFT seeings idle 11.8, WOT 12.4 and cruise 14.7 When warm this engine makes 17 inches of vacuum at 650 rpm. I'm at 3500 feet above sea level. Now for the problem. That idle afr, this is dead rich but if I go any leaner I get surging at idle and it takes two or three restarts to get the motor to idle on a warm start. I could live with this except for cold weather starts. This rich causes the engine to load up when starting below 40F. I don't really want to sit in the truck and fight initial warm up, nor do I enjoy the occasional stall at the stop light while the engine warms up. I went to fuel injection to avoid this. Other symptoms. I get good acceleration when punching it from as low as 10 miles per hour but it stumbles when punching it from a stop. I've got -2 on the accel fuel. Anyway, with all my other options exhausted I'm looking at installing a torker II single plane. Edelbrock specifically says this intake isn't for heavy cars. The Victor JR is an air gap design and I can't imagine this truck is going to be happy starting at minus 10F without the manifold heat crossover. What are your thoughts? Torker II with or without a spacer? Something else I might have missed?
