SuperCharge It

I have a 496 mag with a stage 2 program from whipple and a 5 psi procharger kit gained 12 mph. Very happy with the 496 mag.

So has anyone ever tried the cam and ECU modification? Do you know anyone that has done it?

I think Dustin said his cam kit should be ready in about a month.

Who in their right mind would pay 5 grand for a bbc crank.

Merc parts list 2 crankshafts for the 496 Mag. HO. One is forged and the other is cast, the same part number as the Mag.
They are identified by the casting number stamped on the engine..T10153XA for the forged crank and T10163XA for the cast crank. So, it does appear that they switched to the cast cranks in the HO models. Part number for the HO cam is 881628.
