The first piston number is an ag piston and its legit number. Last time I priced it out it was $400+ per piston, of course cummins pricing. If it works its suppose to be a 12v engine.
I really want to run the hellman intake on mine, it fits better on a CR head than a 12v head. I also want to run the keatin front cover and his frost plug fix kit. Still not sure if I'm going to drill the 5.9L head for the 6.7 coolant holes yet. Thinking about running two coolant lines off the back for extra cooling.
I'm just shootin for small ponies with this engine, around 800-1000rwhp.
The block has a gridle, main studs, VE 5.9L crank and 14mm head studs. Still on the fence for the second main piston squirters, might just go with the stock stuff. Have it all balanced up for 4800 rpm and has a fluid dampner.
The P7100 to CR injection lines dont leak as much as the VP stuff does and the 6.7CR cross tubes are bigger.
