Rockabilly, do you have access to the Stanadyne Injection Pump Specifications for the 4974 pump and the 6360 pump? I don't mean the flow specs I'm talking about the info that the pump builders use when rebuilding the pumps. I would like to compare the two to see what the differences are.

Unfortunately I don't have full access to Stanadyne's information because I'm not a certified rebuilder, and probably never will be.

I have the 4974 calibration sheets but I was mistaken about having the 6360 specs. Since its not a GM OEM pump I couldn't get the specs.... Yet. You can manipulate the Stanadyne dealer portal URL and get a lot of free information. I will try and track down the spec sheet.

But the only differences between automotive and marine pumps are flow cc setting and they use different governor springs. They are basically identical on the inside just calibrated differently.

If I had to guess based on the other sheets the 6360 would need to flow around 105cc to make 300hp
The 200hp 4911 is 68cc and the 250hp 4974 flows 81cc

I have a serious problem, I can't get a IP for my P400 build and I want to go buy this and build a 6.5 hot rod truck with all of the xtra 6.5 parts I have! Someone help me!
Hey guys, wouldn't a 1980 C10 have a 5.7 diesel instead of a 6.2 if it was still original? I didn't think the 6.2 come out until 1982?

Will that tranny hold up to a 300 HP 6.5 turbo? I take it it is a 3 speed. I read that the 5.7 diesel was good for transforming it to a gas engine with gasser oldsmobile heads, comments said the bottom end is stronger than a stock SBC 350.

Also I feel like I should mention that the stock input shaft has a weak link machined into it. So if the pump locks up it will snap the input shaft and save the engine. In order to get BIG fueling from the big bore pumps an all billet shaft was needed to eliminate the weak link in the input shaft. So that being said if the pump fails... you may have catastrophic engine failure.
Back to the P400 Build....
So I figured I'd talk about this, so below are pics of what happened when my 1st Conastoga pump seized at idle, What is the worst that can happen to a 6.5 with one of CDD billet none shear pump shafts at let s say 3000 RPM?

So will it snap the cam, or the crank or strip gears? Of just shear the keyway? Seeing how the keyway doesn't fully engage in the cam gear to IP gear. I guess the only way to no is to do it but I don't think I'm willing to try it.

These pics are with the pump shaft shearing @ idle BTW.
