If you have a good running 5.9 Magnum and replace the beer keg with an Air-Gap intake manifold and Eddy 650 carb what horsepower would you get? I think that the OEM rating was 245 hp with the TBI.




what you've described, with the exception of a regular 4bbl vs. the air gap is the 300 HP crate motor, which on westech's dyno for a MM article dyno'd at 305HP with 318 manifolds up to 325HP with headers (can't remember if it was hooker long tubes or TTI step)

stock mag 360's were rated 230-250HP net (through full exhaust w/all accessories) stock depending on year and model, the 20hp variation was all exhaust system & air box differences, IIRC the cam never changed from '92-02.
