Brainstormin' 440 vs 5.9 ...

Net is 195 hp, 320 ft lbs trq.
I'm guessing that would be about 260 hp / 390 gross ??

• It will have headers and 2.5" straight through muffler on the back. That's gotta be 40 hp (and a bunch more torque) on a 440 from the manifolds, single exhaust and catalytic converter... all in a small single pipe about 18 feet long LOL. When the heads were done, I did remove a little casting and a touch of bowl blending, but I consider it more of a "clean up" than porting. Might be another 10 there. I think I should be somewhere around 300-310 HP gross and maybe 425-450 ft lbs of torque?

Just thinking out loud..... I could be way wrong. But this is my "mind math" :D
