Anyone else have this problem? My car seems to break up up 4,000rpms... *Suspecting carbs*. I have dual quads and a full race cam in my close to stock L-48 in my 76 stingray. Heres the question. G-teched it consistantly at 7.13 0-60mph, and 15.89 1/4 mile =*( (Better than the 19's it was running before my add ons). I have hookerheaders/sidepipes, 700r4 trans, 2500 stall speed, and a full race cam that kicks in like 3200rpm. This was with the aircleaner on, and Stock sparkplugs (AC-Delco 45TS gapped at .45) I just changed the plugs to Autolites, went one range cooler 25. I gapped them at .35 From what my dad was telling me, that makes it burn hotter, resulting in more power. It worked with my 69 Firebird. Well, I feel more power, it breaks up more on the lower end now too, and can't get below 8.01 0-60mph, 16.00 1/4mile with the airclearner off to let it breath a little. I have not had a chance to run it with the cleaners on again. It does have an electronic ignition, unlike my firebird. Does electronic ignition need a bigger gap?
