If you ask enough questions,you will find that a 460 can make god like torque at a VERY low rpm.Diesel like power is common and expected from an average build.Turbos are not going to help that.Positive displacement blowers do that.Since the patents are no longer an issue,Kenny B, and whipple have developed there own sizes.I have no available kit as of this moment.Stock may pickup by turkey day.460 heads have marginal exhaust flow to start with.Jamming twin turbos on it would more than likely result in a fire ball consuming you mach.Running too lean,fire ball.Back pressure from entire exhaust system same O.Too much advance,same O,not enough radiator,ditto.Turbos are more of a violent on/off switch than a linear provider on big motors.Mounting and plumbing turbos are no joy in mudville either.I near wrecked a machine when the tranny contents decided to lube the tires.There are more than a few more things you need to know to avert tragedy.There are other street oriented big power guys here.Not hard to weed them out.Best advice,Learn before you spend. good luck b9h
