.....and every 383 I've had experience with was great for it's cu in and car weight. My 68 RR 727TF with just headers,
484 cam, a DP4B intake (625 AVS) and 3.91 gears ran 13.80's on slippery H70-14 bias plies (terrible 60').
We didn't have any 6-Bbl's or Hemi's to race but mine and even my best friend's 69 383 4-speed RR with air grabber
that was pure stock never got beat by any GTO, 442, 454 Chevelle or God help you if you had a Camaro or Mustang.
We raced a LOT. Multiple times 7 days a week if it wasn't snowing. Pretty much the evening activity every day 68-72.
