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. 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.
