Big horsepower 318 builds

I have no problem with the ability of a 318 producing 500 HP. NA
But I believe it would be in the 7000 or so rpm range. Going to have to spin it.

Don't even know who your arguing with no one on here thinks you don't need to spin a 318 to make 500 hp, people just weren't agreeing with your 8000 rpm assessment. The 477 hp 318 need 6500 rpm the 520 hp 302 needed 7000 rpm.
