To get that power, it's much more than that. Brandon has decent product, and very good pricing. But there's a lot more to it than tightening a few bolts and firing it. The dead simplest is the 440Source B wedge 3.75 crank, rods, and pistons in a 400 block. Then it's a bolt in "build like a factory engine" deal and the cost is similar. The 3.915 stroke isnt that bad. Any bigger than that, and things get harder and more expensive in B wedge block.
