Hey all. I have a 71 Duster with a mild 360. It has about 9.8:1 c.r. mildly ported J heads, a Lunati Voodoo cam with 268/276 adv. duration, 226/234 duration @ .050" and .494/.513" lift, Eddy Performer RPM intake, stock 340 HP manifolds and 2-1/4" exhaust with Magnaflow mufflers. I have two different carbs, an Edelbrock 600 AFB style and a Holley 650 double pumper. The Holley makes this car an animal, no hesitations, power from bottom to top of the tach, but its lacking in street manners. The Eddy 600 has very good street manners, great off-idle transition, but it starts pinging hard after getting up in the rev range. I put in richer metering rods, but it still pings. Either I need to jet it up more, or get a bigger carb if I want to keep with the style of the Carterbrock. Does anyone have good experience tuning the AFBs? If I need a bigger carb, then I'll use the Holley. If I can tune the AFB a little better, I kinda want to keep it on there. Help a guy out, who knows the AFB?
