5.3 crack in block - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pulled my heads tonight to do head gaskets and snoop around a bit and of course found a crack.

Funny thing is this motor came in a truck already running and I was told it was a 6.0 but I quickly realized it wasn't once I got it out of the truck. The seller was pretty cool and refunded me the cost of a replacement so I am happy.

The question is do I pick up a real 6.0 motor locally for 7-800 or just get a 5.3 and move along?
Also if I go to a 6.0 do I need the ECU from that motor? I have a PSI harness already ran I would like to not have to mess with any wiring if possible - if that means 5.3 then I will stick with the 5.3.
Thanks
