1500hp 6.7 Cummins tare down, IT'S HURT 

Looks like mine. I have D&J wrist pins now. 1450hp on cast pistons 🤘

👍👍 can't spend enough when a person wants to play I guess...idk anything about that 🤣👍👍👊

Car guys must hate it when a big old Dodge truck eats every car at the track🤠

Ya know Rob, I don't like the way the top of the rods are "slash" cut. Haven't seen this on gas engines. And besides, with that weight and size of that wrist pin, a little extra weight on the rod small end is not a big deal. Looking at that bushing says there is too much concentrated loading

If only Cummins used Deere sized wrist pins then they would be good till block splitting power levels no problem.

D&J Precision Machine Tool steel wrist pin, Is there any Canadian dealers. Dirty Diesel Custom showing them for $697.50 CAD. Not sure they stock them.

So that was orings and a mls head gasket? How much hp is a mls gasket and 625's good for before you should oring or fire ring the head? Thanks!

Excellent, thanks. Have you ever run Black diesel at the track and what was the difference between straight diesel and the black?
