The guy on eBay has both types of NOS, one for $599.00 and the other for $1,499.00 or so, I'm not saying that that is the value but what is? </div></div>the only difference is the $1,499 crank is cross drilled and the $599 is not. $900 more for cross drilled. </div></div>

It is my understanding that the vast majority of these later 6223 cranks were not nitrided or cross drilled, while the early ones mostly were.

I have taken apart many original 427 engines over the years and most had the 6223 crank not the 7115.

I have several 427s here at the shop and all have 6223 Cranks.
