    long body 6.2 injector ?

    The nozzles are longer for the long body. I experimented with them for a while with mercedes nozzles . You have lots of nozzle options for the long body . Short body just 2 or 3 options.

    5.3L L33 Mods

    I built a 2002 5.3 for my S10. I used the stock heads,unported. I did upgrade the cam and valves springs. It runs pretty good ,ran 11.98 @ 114 mph, with terrible 60 ft.

    6.5 direct injected heads

    Don't recall it starting hard, but lacked power ,and smoked pitch black. It had a soft hollow knocking sound ,instead of the normal clatter . Was running an unmodified ip at the time ,just turned up. Might have worked better with one of my modified pumps .

    6.5 direct injected heads

    No ,the pistons were fine. Still using them actually.

    6.5 direct injected heads

    I had them at 3800 psi. The pump was just a turned up .290 plunger.

    6.5 direct injected heads

    One time I cut the precups so they just became headgasket holders. The injectors sprayed directly on to the piston tops. I drove it for a few days ,but it had very little power.

    6.5 Block Oil passage diagram?

    I opened#7 and blocked #6 ,and plugged the cooler ports, the cooler bypass is now nonfunctional .

    6.5 Block Oil passage diagram?

    I have my cooler ports ,and filter bypass plugged ,and run the filter only. There's a cup plug in the oil filter base that must be removed if you block the cooler ports . There is also another bypass under the cup plug that is for the cooler . I removed my cooler and dual filters ,because it...

    Wh1c 14cm housing

    I have some 12 cm housings ,make an offer if you want one. I also have a 16 and 18 .

    Military DB4

    I think the nozzles are .040,they are all the same . I also discovered Ford rotors are not the same as Chevy. The injection hole is offset backwards . Although some rotors have no offset,usually ag pumps and 4 plungers ,and can spin either way . High pop pressure does restrict fuel ,but it...

    Need Some Help With My DB2

    It goes in the hole in the governor spring holder . The same hole that the pin / guide fits in. It is there for the last stage in governing ,3600-4000 rpm , depending where you set the guide nut.

    Military DB4

    Took my latest 2 plunger apart,and installed one of my better cam rings ,and a 4500 rpm gov spring . Runs pretty good,30 psi boost, with a H1C -18 cm housing ,and has been starting hot so far. Same pump wouldn't start hot before modded.

    No Oil Pressure

    I've had,it happen a few times. To prevent it from happening,I drilled a .040 hole in the plug ,were the filter bypass used to be. I'm also running a Wix oil filter for a Duramax, so the bypass is in the filter instead.

    Small vs Large throat precups

    About like rod knock at part throttle . The small ones just clatter,much better sound IMO.
  17. 6.2 turbo

    Small vs Large throat precups

    The small ones have a softer clatter,the big ones more of a knocking sound. I'm running the small ones currently, they work just fine,if not better than the big ones.

    Military DB4

    The DB pumps have a better cam ring, not a direct swap though.

    Military DB4

    Got it up and running again. Ditched the ag governor and installed the db4 cam pin . Runs great when cold,but hot it surges a little at high rpms. It starts hot ,but barely . 3500 pop psi is too much for three pumps in a row now . One was a bone stock military take out , fuel screw turned...

    Surging can come from different things ,but not from running with no leafs.
