Offset Grinding 428 crank

[DavidNJ]

What would make a 35 year old forging worth using? Was it 5130 or 4340? Was it a non-twist forging?

I don't know dave.I'm starting to wonder about this guy.I don't want to mention any names.I've not heard of any problems with the scat crank as long as its balanced properly.he thinks if its made in china its no good.

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

The 428 cranks were cast, not forged.
