You can build a 400-450 hp 360 with the stock crank and stroke for 3500.00 in parts. No need to get crazy and stroke it. In my opinion it's not worth the hassle. You won't get any more power out of it for what you want.

I've built 4 or 5 of these that are still running today after several years of use and abuse. The first one I built made 434hp at the crank, didn't balance anything and no shakes.
