Then it's just the oil pump and special compressor, although you could go belt drive, that is true. Center section of the exhaust is the same, small or big cam or 743 for that matter. One bolt hole on the bellhousing has to be oblonged slightly and the small cam one can be reused. Then you order a new big cam pancake accessory plate which is available from cummins, 1800 dollars. Now you pick up your used upright big cam. The easiest way to do it, is to get a pancake small cam, because those can still be found although they are drying up quick. I can get you part numbers for the stuff you need, most of it is still available. I have the parts catalog for big cam cummins. My small cam still has the oil cooler up on top. On the big cams there is a plate to move the oil cooler down beside the engine instead of up on top. The compressor is still gear driven, it is just a different model with a drain on the bottom hooked up to the scavenge stage of the oil pump. Additionally you need the scavenge style pump (pancakes have a two stage oil pump). 855's were the standard universal block with a different oil pan and accessory plate. Myself or another guy in the crowncoachjunkies list called on every single one of them.
Keep us posted, good to see old iron coming out of the wood work.All those listings on adelman's are already sold overseas.
To give you more basic answers to your original question, the 350 is a fine motor. I spoke with the last man to drive it, he said grossing still 78,000 across I-70 through wheeling, WV was just a matter of splitting out of OD and go on across the grade. Engine that was in this truck was a 1981 350 built to cpl 625 400hp at 2100rpm, with the air to air and a #15 button pushing through a 15613 trans into 3:70 gears. Making changes on these O'l things can be like the little old lady that pee'd in the ocean. Most are listed in the earlier responses. This is a 1987 Big cam 4 in a 95 model truck, lot of little tricks to get a few extra ponies out of it. But getting it cranked up to factory specs would include changing all 6 slugs, injectors, and changing the time on the cam. As mentioned earlier, you can do a lot with a 350.
REPLACE AIR COMPRESSOR ON CUMMINS BIG CAM 350 SERIAL NUMBER
Told the guy that owns it now I'm stopping some day and getting the serial number and cpl number off of it. If it was based on the CPL and this truck was to be rebuilt with the CPL of a high HP motor would that work? I would also assume that the power rating comes down to the pump but I could be wrong and want to know before I buy just cause it would be another expense to replace the motor for a high HP down the road.Įver get the chance and think about it. So the big question is, does a BC2 with a rating of 350 have the same insides ( pistons rods crank cam ect.) as a 400? or are all those things changed depending on what CPL it is? I don't know a whole lot about this.

The truck is really cheap and I was going to buy it and slowly get it back to the point where it could go on the road again working every day and then as I made money with it update things on it. Im waiting for the owner to get me a serial number to call cummins and get more information on it. Reason I ask this is because I'm looking at a truck right now with a 350 cummins by the year I'm guessing it's a BC2. I did do a search on this and came up dry.Īll BC 1 2 3 4 are 855's with different power ratings and a few items changed here and there? I know the casting in the blocks have changed a little bit.
