360 Magnum vs 340 mild street build - my experience
- They are the "unported" SM heads. 730 to my front door on Black Friday Sale is what I paid.
- I don't know the power of the engine, there are "ball park calculators" online that can try an guess. It runs 12.9's with 3.23's, stock converter, and about 3400 lbs at the start line. My cam is very small (less than a factory 340), so I am NOT taking advantage of the heads.
- Fully ported Magnum heads would outflow my "untouched" SM heads is what I'd guess.
- Keep in mind, the car only went about 2 tenths faster with the SM heads vs untouched stock 360 heads. Again, that would be due to the small cam in my opinion.
Forget ET, tell us how much MPH you picked up at the stripe, that's a far more accurate indication of horsepower
