So I got this bare gen 4 6.0 block for free from my roommate who bought it it as a package deal with some other things. Problem is the guy doesnt remember what it came out of or what year either. Ive researched the casting numbers and have found nothing other than the numbers in front of the passenger head tell you month/day/year was produced but this doesnt begin with a letter like the others.
Rear of block 12610679 AA
Front of block looks like 31806
Id like to know what it is so I can plan a build accordingly but if all gen 4 6.0 iron blocks are the same I may not worry about it.

Ok you're the second person to tell me there is no diff in the blocks. I just like to do/buy things once and I research a lot so I like as much info as possible.
Plan really is to bore it .030 over and stick with stock rods and crank(budget restraint) for a decent 370 with stock 243 or l92 heads(undecided yet), cam and than down the road throw some boost at it. This is all going in front of a t56 inside of my 99 Dakota regular cab for some tire frying tail wagging fun.

Its a gen4 block so it uses that latter style so that wasnt a concern of mine, just more so if the internals were block/gen specific. I know of the difference in reluctors and cam gears and such but was more concerned with the expensive things such as crank, pistons and rods.
