If you take the best factory man motor every produced, the GM 454, and bore it .060 over you get 468 cubic inches of big block power. This overbore is incredibly common, and even if you had a block that would clean up with a .030 overbore, you probably would still go to .060 just because. If you want more than 468 cubic inches, the next fun logical step is to swap in a stroker crankshaft that goes from the stock 4.0 inch stroke to 4.25 inches. This quarter inch of stroke, when combined with the .060 overbore will result in 496 excellent inches of big block Chevrolet. (Editors Note: Every time I say, or read, Big Block Chevrolet the announcer voice in side my head makes it sound ultra bad ass. Just saying.)

Many people argue that if you have an average high mileage big block 454 and are going to have to have the crank ground, the rods reconditioned, and buy a set of pistons anyway to do a rebuild, then you might as well spend a few dollars more and just buy a stroker kit and be done with it. There is some logic here depending on the condition of your engine. But what does Richard Holdener think?
