383 build help one piece at a time

Something more to think about.................

Years ago, Steve Dulich did a build up story in "Mopar Muscle" with a stock spec re-manufactured 383 Magnum, gave it a break in/base line run on the dyno. Magnums were rated from the factory at 335HP, he got real close to that, +/- 5, I think. He then started adding typical bolt on stuff, headers, carb, intake, showing on the Dyno what each piece added. Before the cam change he had just a lick over 400. I would think that should work out nicely for a fun, go any where driver "A" body.

Good luck
