how well does a 440 source crank, rods hold up in the blown world? And/or is anyone using there components in a blown application? looking at their 400/470 crank and rods in a Hampton 671 topped 400/470 stroker, and to get the 8:1 compression run a Trw Forged piston, all said it should be around 10lbs of boost. also for the gentelman/ladies running a blown application, what type of ignition are you running?
