1968 '340' Barracuda vs 1968 '383' Road Runner

Chick,

The popular 'Stock Cheater Upgrades', for the 1968 '383' Road Runner,

Was to get the;
* '284' Hydraulic Camshaft (.484 Lift / 284* Duration}
* Chrylser #3412004 (Matched Lifters)
* Set of Adjustable 'Push Rods'

If you wanted to push it, Engle Cams had a {Double #98} which had a .498 Lift / 298* Duration.
The 'rough idle'.......would risk getting picked up by the Track Tech's.

Then pop on the Carter #4428 AVS 750 CFM Carburertor from the 1968 440/375 HP 'Super Commando'

The Carter #4428 was a 1 11/16" Primary x 1 11/16" Secondary 'square bore'
Carburetor that bolted directly on to the 383 Intake, which was already bored-out
to those specifications.
