Quadraboggin\' at low RPMs Sorry for posting a bizillion times on this, but I think I got an idea of whats up here. 355 motor has vortec heads, edelbrock performer intake and .447/.462 210/218 111 seperation cam advanced 4 degrees. The basic deal is that it does not like throttle at low RPMs. It idles great and all that stuff, but I have to have wound up to get any throttle response. Try giving some gas right after I shift to second and nothing. You can baby it up to speed and then I'll be fine. I was thinking that spring for the power piston in the Q-jet maybe too stiff and I don't have enough vacuum to make it work properly. Whats a good primary/secondary rod and jet combination too, or is stock fine?
