1968 Road Runner '383' vs. 1968 Competition

Performance Wise,

You could make the 383 {Road Runner or Super Bee} run nicely on the 'street'
with just a few 'Mods'.

'Package Stock' Dealer Option
* Camshaft 'Hydraulic' ........... .484" Lift / 284* Duration / 56* Overlap
* Matched Lifters .................. -.0005" Undersized
* Edelbrock Intake ................ #DP4B
* Holley 780 CFM Carburetor... #3310-1

* 3.91 or 4.10 Gears, and you were good to go.

Note: You didn't need Headers for the Street, as the 440 Exhaust Manifolds {2.50" Outlets} were
more than adequate for exhaust flow breathing.
