69' Road Runner

My friend has a 1969 Roadrunner with a 383 and he claims he pulled a 13.5 1/4 mile time. His car is dead stock except for two 4 barrel carbs. Could he really pull a 13.5 with only new carbs or is he making it up?

Are there really 383's around that have never been rebuilt?!?

What gears does he have in it?

I'm not sure what gears he had he sold the car a little over a year ago

A "dead stock" 383 with 2x4 carbs sounds a little fishy, too ...

i seen factory stock 383s push the roadrunners into 13.2`s with slicks, i seen a 426 hemi ( not much more hp/trq than a stock 383 ) and they pull a 12.8 with slicks stock.

The best years for the 383 - 335HP @ 5200 RPM / 425 TQ @ 3400 RPM.

426 Hemi - 425 HP / 425 TQ (conservative) and they'll run a lot faster than 12.8!
Hemi's rebuilt to factory specs routinely produce 450 HP on an engine dyno ...
