The new LS platform is wild, there's almost no limit to how much power one of these stock blocks can handle. You used to have to spend a good bit of money on a first gen small block to get that much power. But comparatively speaking it was still cheaper to make Chevy power than most any other brand. They have just set the bar higher with the LS motors.638 HP Small Block....the first 327 I built was no where near that.![]()
