It would cost more than it would be worth to stroke the 428 crankshaft. Sell the 428 crankshaft and use the Scat cast steel crankshaft. I have used these in engines over 700 HP for three years now with zero broke. The way that the engine is used in most Cobra Replica cars you will never hurt one. I can get you a new Scat stroker crankshaft for 695.00. This would be in either a 4.125 or 4.250 stroke. These use a 2.200 BBC rod journal and most people use a 6.700 to 6.800 long rod. We can also get you a nice complete kit together as well for about 1895.00 Thanks and good luck, Keith Craft
