| 428 CJ indentifiers |

Here's a few thoughts from my painpill laced mind that might be useful.
The CJ and SCJ blocks have a "C" etched at the back of the block. It looks like somebody took a nail and scribbled it in by hand. Standard 428 blocks have a sloppy "H" on the back.
Ask the seller to send you a picture of the back of the block so you can see if it has this etch or not.
BEWARE though! Real scumball scammers have been known to take metal filings from the same casting, mix them with clear epoxy, and make false letters and numbers. Then they can be either painted over or dirtied up tp hide the forgery
If you can physically inspect the part, ask to scrap the casting numbers with a pocket knife. The epoxy will peel, real cast in numbers obviously won't. A scammer will definately object to this. An honest seller might object until you tell him that you are just protecting your investment.
If you it looks funney and you aren't allowed to check, walk away.
Standard CJ's had C7AE-B rod casting that had been drilled out to accept a 13/32" rod bolt. Take a 9/16" socket to check as the standard 390 rod bolt uses a 9/16" nut.
As Shoe stated, C6AE-C rods are a standard production rod. Nothing special. The SCJ used cap screw rods with the casting number C6AE-E.
The SCJ engine, because of it's heavier rods and pistons used a crankshaft spacer with a counter balance cast in that looks like a hatchet. No hatchet counter balance, no SCJ as far as I'm concerned.
As Shoe mentioned the SCJ had a unique crankshaft.
You would do well to listen to Shoe's advice on this one.
Gotta run! Hope this helps!
