I doubt that you would get more then 245.... The Cam isn't very much on the engine as it is. Intake, Headers and Cam then it will be working much better...

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.

Patrick is right. The crate motors rated at 300 hp have made 325(magazine hp) with TTI headers and the M1 dual plane. The truc motor has a slightly bigger cam and if you use the eddy air gap you get a better manifold so I would say you should make 325 real world HP easily. The carb may be just a hair small but not bad.
