I saw one that Harold Bowers had apart that just quit running, while going down the road. The cam was broken into 3 pieces and 6 bent push rods. Harold thought it was a dowel pin that dropped out but it turned out to be one of the 10mm bolts that hold the front cover on to the engine. He put in a new cam, push rods and some lifters. This was about a year and a half ago and I'm sure the truck is still running. Maybe you'll get lucky - lets hope.

The P Pump has a lot more potential, but I don't like them on the street because of the terrible rattle P pumped engines have when they are advanced. The VE has that wonderful mechanical advance that makes the idle much much quieter.

 

Please use PM's for any further discussion of available engines.

 

hey guys thanks or your help and all the insight on my situation, i was informed that our engines are sleeved, is that true and if so what do you guys think about my idea to resleeve, all new pistons(a performance grade) , new rod bearings, of course all new gaskets, and a performance cam . if anybody has some input about this i would appreciate it since im a little diesel challenged also does anyone know where to get these parts that i would need? thanks

 

Get a Cummins B series rebuilt kit..... I don't know if there are any first generation aftermarket internals short of custom manufactured pieces that you would have to pay a LOT of money for. I know some manufacturers of pistons, rings, and other engine components who would make you custom parts, but short of that I don't know where to get performance Cummins internals.

 

I don't think that our eng or sleeved.......thay can be sleeve but would be vary expencive.
I now for a fact that the 24 valve and up are notsleeve from the fractory!

 

FlashGordon is right: Look Ma, no sleeves. That is why you don't have to be quite as careful about coolant. You don't get the electro-chemical erosion in our engines that you get in the big units.

 

Selves also move a little in the thermal cycling and can cause coolant leaks around the bottom of the sleve. Don't do it! All iron is best!

 

hey guys my brother found me a block but said the #1 cyclinder has to be bored .10 over because it is a little messed up. what do you guys know about boring just one cylinder and is it okay, do they make pistons to fit a bored engine, and would anyone recommend boring all the cylinders like .30 over as a way to make more power, sorry if what i just asked is a super dumb idea, (boring out a diesel) but im just curious and im more of a gas engine guy, still have lots of diesel stuff to learn.

 

I had a friend that was real low on money. He and I got his six cylinder Ford machined for just one bore. That thing wanted to shake your fillings loose above 60.

 

You never, EVER want to only bore one cylinder. It's impossible to balance and you will get a split crankshaft for your trouble. Pistons come in many oversizes, look into marine pistons because they usually have a deeper dish (lower compression ratio).

 

excuse my ignorance, but is lowering the compression a good thing, as in more power and is boring all the cylinders out to like .30, .40, .50, or .60 over going to increase power or will it hurt my engine at all? also since im in the question asking mood, what does advancing the fuel pump actually do? thank for the insight on engine boring, i kind of figured that boring only one cylinder out would give me problems.

 

I would only bore the amount needed to make that cylinder good again. You can only take so much material out so in case you need to bore again in the future only take out what you need. Of course you will need to bore all the cylinders the same and use the same pistons. Get all your parts from cummins, they can get you .10, .20, .30 over pistons i'm sure.

Lowering compression in itself isn't going to give you more power, neither is boring your cylinders out as big as you can go. Many of the high high HP guys will lower their compression ratio so that when they run higher manifold pressures so they can inject more fuel they will keep their peak in cylinder pressures down. This helps save the head gasket. This is my take on the whole thing. The problem I have with lowering your compression ratio too much is that when it gets cold the engine will have a much harder time starting. You don't want it to start like a chevy do you? lol You can also get thicker head gaskets to lower your compression.

Also boring the cylinders out isn't going to change your compression ratio, as its the ratio of BDC volume to TDC volume so that ration won't change.

The high HP guys all basically run stock internals, maybe the 1000+hp guys have stuff special made for them but stock internals are good for 600+hp. A cam would help, but even at 600hp I don't think people really run a block girdle or anything.

So basically if you have a block that only needs one cylinder bored .10 over get all the cylinders bored .10 over and get the matching pistons from cummins.

 

I wasn't talking about lowering it a lot, just a little. By the way, boring increases cubic inches which increases power, to a point. When the walls become thin they distort under pressure causing blowby past the rings.

 

Thats true but I believe the benefits of boring on a diesel are much less than boring of a SI engine. Unless your are able to take advantage of the added volume with a ported head and better cam.

But just from a longevity view I wouldn't bore anymore than needed. I wonder if the high HP guys bore their engines?
