The 69 runner was the fastest,cammed 383 high rise and 750 holly with headers,4:10 rear and 3 speed auto. The motor was built before I bought it so I'm guessing on it. Put electronic ignition on it and holy cow! What a difference.$550 for it.
I was poor as dirt back then,it got 10mpg at 50mph. The RT Challenger was a 383 4speed with 3.55 gears,paid $300 for it minus motor. Put the 383 out of my 68 Roadrunner in it. Traded it for a 70 Roadrunner that got stolen. :-(
Man oh man was that fun.
