Usually it gets in the 20's, I have seen as high as 27 hand calculated.
It is a pretty good fit for the truck. It pulls hills pretty good, no speed drop. I have towed a small trailer with it but stay at 55 mph in fourth gear to do so. The only time you really see a lack of power is trying to pass someone in a short distance. This would probably be remedied with a little tweaking on the pump, and a 3200 RPM gov. spring. I haven't changed it from stock, because of the little 5-spd behind it. As far as weight, it doesn't seem to mind it too much, it didn't really sag much after the swap.-Nicholas

What "little 5 speed" trans are you running? I have a Dodge (2wd) with a 3500 in it, and am hoping it'll be able to be used on a swap. I've lined up the adapter plate, but what (and where) did you get the proper flywheel?
Dang nice job!

Joel, the pump is the gm style unit that came with the engine. The pressure side runs from the pump to a hydro-boost and master cylinder from a '94 Chevy 3500 454 dually, then to the steering box.




Dieselbiker, Thanks! The 5-spd in my truck is the Muncie 5LM60. The adapter and flywheel came from a P30 step van with 4bt. It will bolt right up to the gm transmission, but you have to get a little creative with the slave cylinder.-Nicholas

That made a real sweet truck out of that. That is cool, I would like to have one of those P chassis trucks to strip and do the same thing to have a better econo ride. LOL

Sweet idea dude, did you have to do any major work on mounting the engine in there? Thought about doing this to a 1/2 with the diesel 6.5 or the 3/4. I think I would probably go with the auto trans so the wife could drive it if need be. Wish I could get her to drive a 5 speed..... Stubborn red heads.

Depends what you call major work. It took me about 40hrs to put it in and get it road ready. It was way easier then my F350 conversion, the way I am going, it will be 40 months before I get it finished.-Nicholas

What engine mounts did you use? I studied the pics in this thread and can't tell what you used for sure. Looks like the engine fits in there pretty good though.

No cutting of the firewall, used the mounts from the P30 donor, isolators from an '89-'93 Dodge ram with the Cummins. I don't think I have any pictures of the mount, if you look close in the pictures of the hydroboost, you can see part of one. I will look to see if I have any pictures in the camera, when I get a chance.-Nicholas
