383 = no love

383 4 speed 68 Road Runner. Milled heads, richened Carb, factory AVS. Headers, Gears, I don't know what ratio, slicks. Low 13's, breaking into the high 12's. Tuned constantly by the original owner for years. All your theoretical BS means nothing. Any Mopar engine will run great if you know what you are doing and can tune it correctly. 170 up to the 426 Hemi. You couldn't give me any Chevy, if I had to drive it on the street.
