Will King, Floyds Knobs, IN, 1966 Dodge Charger 383

First you magazine rocks. Now for the matter at hand. I have a 1966 Dodge Charger with a '68 383 in it. I am looking for the best performance out of it that I can get but still be able to have a easy cruiser. (Too many people on the street think these cars are grandma tanks) Right now it is stock but I have put a 750 cfm eldabrock carb on it. What would be your advice on intake and cam?. Keep in mind that I have AC and no power brakes.

Will-

The stock '68 383 was a pretty hot engine to begin with: 906 heads, good intake, 440 Magnum cam, 10:1 compression, etc. About the only think I'd change is maybe a tad more cam - the MP 280-degree hydraulic would be a good starting point. The stock intake is a pretty good piece, the the lack of A/C mounting bosses on most aftermarket manifolds is a god reason to stay stock!

Beyond that you have to think "system"...i.e., incremental changes in virtually all parts of the engine - no magic bullet. Head work, small headers (think: Schumacher Tri-Ys), 2.5" duals, smallish single-plane intake, etc. - with upgrades like this, picking up 50 - 60 HP is pretty easy.

In the meantime, be sure your stock engine is all that it can be. Is the timing right? Compression equal in all 8 holes? Secondaries opening fully?
