Quote: I'd go with the 360 magnum, Roller cam, more efficient heads. Better fuel mileage, cheaper parts, not by much but still a little cheaper vs a 383. I love my 360 magnum been a solid engine for me.
One factor being ignored is the roller cam- I'm sold after playing around with the 5.9 in my Duster that a modern roller cam is THE only way to go.
I'm old school who has used a dozen or so purple shaft cams to good effect but blown away with what you can get away with with a good roller. There is no way in hell you can make the same lobe with a flat tappet cam that you can make with a roller.
My Duster is just as happy lugging along at 1500 RPM in OD as it is winding out at 6000 RPM.
That being said I'm not sure what the purpose of this thread is- The OP looks to me has already made up his mind before posting and has all 383 parts and no magnum parts.
