I recently picked up a vt365 and eaton 5 speed super cheap. Looking at aftermarket internals and such. I want to go mechanical to save for the complexity of swapping with a full harness and computers. I have found a couple dead threads that didnt quite answer my questions. First off, for my application, what is safe to pull off and sell thats actually worth something. Besides the obvious ficmhpop turbo and injectors. Im very new to this fuel system and engine diagrams arent painting a clear enough picture for me. Second question is where is the most reliable location to gear in the pump. Ive seen the 7.3 trucks in the timing cover and also heard of driving them off the hpop location. Seen a belt driven pump in a duramax massey. I am waiting to rip it apart until I have some sort of game plan. I know it may be a trial and error thing but im willing to give it a go. Extensive background in fab and custom cars, but new to anything except the old 12v's. Anything pointing in the right direction would be fantastic. Motor will end up in a rat rod of sorts with a tube chassis and "slightly modified" (lol) front suspension.
Okay.. upon hours of endless digging I've found
This did answer most of my questions as far as how to drive it.
Now i just need to know how to time it. Are they timing to the cam and intake valves or the crank and TDC?
You would have to mount the injector pump where the HPOP is, or a belt driven pump. The HPO branch tubes and oil rails/stand pipes are what feeds the injectors the HPO. Its going to be tough as the fuel lines themselves are cast into the head. What are you going to use for injectors?? You'll have to find a way to mount them in the head.

http://i22.photobucket.com/albums/b3...strokedout.jpgThe only thing to gather info from is 7.3 builds. As of now I've read quite a bit about 8.9 cummins injectors. I have a mill at my disposal so the injectors dont concern me as much. The 7.3 guys just build valve covers with the injectors and lines in mind. Looks fairly simple. I'm not entirely sure with what is done to the old fuel line? Just left alone or welding shut? Who knows lol
no offense intended...but if you're wondering about what to do with the stock fuel lines, you may be biting off more than you can chew.
first thing first, you'll need to drive the inj pump off the cam gear. the gear driving the inj pump will need to be the same size (diameter) as the cam gear to keep the injection events timed properly...so you can ignore the belt driven IP option/recommendation.
start by having a gear made, then you'll need to design a rear cover (unless you're going to remake/re-gear the cam & crank gears to be on the front of the engine, in which case you'll need a new front cover as well.)
You may want to address the head sealing method while you're in there...a lot of 400hp HEUI engine's have multiple issues with gaskets.
drilling/tapping the block for larger studs is an option we've used on other engine platforms in the past..aside from the gasket itself.
Pulled it apart today and it's alot more obvious now that i have seen it. I actually am picking up another 6.0 for parts so I may be able to modify the extra cam gear. Trying to source a pump now. Ive heard mack e9 some JDs and so forth. Its slim pickins if you cant afford the billet stuff. And my question about to fuel lines....I mis spoke. I was wondering if the 7.3 guys were blocking off the rail in the head that delivers fuel to the injectors from just the outside or if they were inside there welding holes shut. But after seeing the heads off i have a pretty clear picture.
And no offense taken at all. I chew pretty decent.... just used to a little different flavor thats all. I'll learn quick. If anyone has a source for a 8 cyl bosch for around a grand let me know. Thanks
