i have an 81 buick regal with a chevy 350 engine i had built but i am still not getting good acceleration from the start. i have a 650 edelbr. carb. a airgap intake and comp roller rockerarms, headers, 350 tranny with 2800 stall. i dont think im getting that much power out of it. i've done nothing to the rear end so it is still stock. what are some tips to get me more rear wheel power out of this engine.
