383B Stroker Build

That's odd-I noticed they don't sell a kit, but they do sell the crankshaft itself to fit in a B block...you could run one, but it would be custom piston or rod length...lamesauce.

Yes a stock 440 crank can be cut down, or the block clearanced...Fisher did the 440 forged crank in a 383. If you haven't seen his build, he used a 440 crank, Diamond pistons and H beam rods, Edelbrock heads, a Lunati solid 272/280 cam, can't recall intake and exhaust, but it cranked out over 500/500 on the dyno IIRC.
