Pulled again yesterday and got another 1st, but broke the yoke on the drive shaft...

And the manual tensioner is still working great! Hit 4,800 RPM's that's pull...

Did a pull last weekend and lost the water pump and got the engine hot. It blew the top radiator hose off. Still managed a 4th out of 35 trucks, it was a diesel shootout class, all diesel pickups compete in the same class, from stock to fully built trucks with Wagler billet motors. Here's a video of pull.

Water pump housing damage...

I pulled the motor, heads are going to SoCal to get checked out. Short block looks fine.

Glad most of it was fine. One hell of a run that was for sure.

Was the old water pump pined or welded or just a stock pump?

Welded...

 

[1FastBrick]

Did the weld give out or are the bearings just shot?

I haven’t updated this in a while. I ended damaging both heads when water pump failed. I ended up buying Edelbrock heads and a Wagler billet water pump so hopefully this doesn’t happen again...

 

[duramaxzak]

I ported the Edelbrock heads a little

Custom billet CP3 wheel

Cleaned up the fuel feed and return lines

Updated to a FASS 260 pump with Woldfab mounting bracket

Almost ready to start up.

I updated injectors to 250’s from 150’s.

I also made a C3 Oiler, and no truck doesn’t have a ATS tranny in it...

Are you worried about fuel volume at all with 3/8" vs the typical 1/2" line or is the image you for the brand? Looking on Amazon they do make a 10an to 2x 8an. Has me thinking about re-plumbing my fuel supply and returns now....... I know the inlet on the pump is obviously smaller than that but I'm wondering if the fuel volume directly at the inlet may help.
