Engine/Transmission (1994 - 1998) A quick injector/DV question

[Signal73]

My 370's should be on my doorstep in the next few days, I have the 175 pump. Should I wait and see how it runs with them or should I just get some 191 dv's and do it all at once?

I don't know what your goals are, so I'll just relate my experience to you.



I noticed a power increase as well as more black smoke with the dv's. Also they eliminated the engine 'lope' that just straight 370s gave i. e. smooth idle and better fuel delivery. They were a definite plus IMHO. You also might look into getting a 3K governor spring kit and timing advance. You'll swear you've got a whole new truck.



Hope this helps,



Miles

hey '73,



That was quick! :-laf



I'd hold off on the DV's for now just to see how it runs with the 370's alone. If you find it has a stumble, increasing the timing may help too. Try to get in touch with HoleshotHolset as he has quite a bit of experience with these and may have some insight on the best way to set it up.

cummins+babes, Thats what I heard was the lopey idle thing would happen. I guess I could do a wait + see thing and go from there. Hey Paul, I got them from that place yoiu mentioned, and you think that was fast, I was on the phone w/piers and got the 3K GSK, and a 03 track bar conversion bracket also :-laf . I would have went on the cheap and got a lukes link, but apparently have a aftermarket bar already and it wouldnt fit.

the added power from the 191s is quite nice and noticible espesially on a smaller pump

I did mine seperately.



I figured in case I ran into a problem, it would be easier to trouble shoot 6 injectors instead of DV's and injectors together. Get what I'm saying.

Must be catchy... I had ordered a 3GSK and DSS last Monday This week I stopped at a Bosch shop to "inquire" about having the pump bench tested/calibrated. Mucho bucks as he will only rebuild it not just calibrate it. On the plus side, he'll set it up to flow whatever I want! We'll see what the future brings...

Injectors got here today, I know what Im doing tomorrow I guess :-laf . Anyone know what the rubber spark plug boot lookin thingys in the DIPACO install kit are for?

They're only task is to take up space in the tool box :-laf

OK! the new showerheads are in and let me tell anyone on the fence about these things to jump off and get em! It took me like 7 hours :{ To get these things in but I did have some side projects like painting the injector lines and boost elbow. I took it out for a spin and the smoke is nowhere near how much I thought there would be, which is good. Power is awesome, No lope or flutter with stock D/V's Oo.



Some points id like to bring up.



1. The DIAPCO install kit comes with junk :-{} return line washers , the holes are to big for the banjo bolts and when you tighten them they squirm and leak. I need to replace a few tomorrow with the stock ones i noticed a small leak on the #6 injector.



2. Bleeding the air out of the lines is a m/f er', I must have been doing something wrong, because it took me like 10 starter cycles to get this thing running



3. 10 y/o injectors dont come out so easy. I needed a 4' breaker bar to help me out. on the # 5+6 cyl, the holddown bolt was rusted to the injector body, and the injector spun in the hole while I was loosening the nut. The ball made a little groove when it spun, I hope its not a problem.



4. I discovered the Valves on my truck were never touched yet, the bolts on the valve covers have no marring of the paint. Noticed that when I took off the vanity cover. put that on the to-do list.



5. 1/2" clear tubing rigged to the shop vac cleans out the injector bores nicely.



I guess thats it. anyone have any questions or comments, lets hear it.
