The 383 engine is original to the car and was rebuilt by Carl Ruth of Reading, PA. It is .030 over bored with a slightly more aggressive cam. The pistons are 10:1, with hardened valve seals, electronic ignition, clutch fan, and a windage tray in the oil pan. (Original oil pan included). The stock transmission was also rebuilt. The car has the original 3:23 Sure Grip rear end and can cruise at 18 to 19 mpg.
taken from an E Bay ad. . . . . 18 to 19 with a Big block ??? . . .10 TO 12 sounds more realistic. But I'm sure someone is gonna post how there buddies 440 six pack with 4:10's got 15 mpg all day or their 383 Roadrunner with 3:91's got 17 mpg all day.
Let the controversy begin. It's all fun and games,so lets begin :lol:
