Small block bottom build horsepower limit

With the average parts available us eg. trick flows, 500 hp is the new reasonable goal.

From the sounds of it, it makes it's 735-770hp by 7500 rpms which should put peak tq around 585 lbs-ft which is 1.55 tq:cid.

That engine would last only for a few dyno pulls.
Most of the challenge builds are just dyno mules
