who knows where i can find parts for a Cummins C-265 V8 diesel engine?

you probably could have the part machined at a pretty decent machine shop. Just take the old part for them to copy from

Hey Guy, I had a close friend that owned a used part ( Junk Yard )

business.. If he wanted a certain part for some one, he would get in the parts screen at his office and pull it up..

I do not know what the service cost, but, you might try it.

This was in Tittusvill, Florida.

I am sure that just about every " Junk Yard " for cars would have this service.

if your quite caught on swapping the engine.. the least complicated thank you to try this is to purchase a truck with the cummins motor you desire to alter on your gmc. that way you have each and every of the mounts, gasoline gadget, electronics, transmission aspects, 4X4 aspects, ect.. you will in fact shell out the two automobiles and alter the cummins truck into your GMC, you would be wanting some companions and somebody who can weld o.k.. and in case you sense which you would be able to get your funds decrease back, positioned the V8 you dont want into the previous cummins truck. i did a v6 replace right into a 4 cyl honda civic with a chum, while we did that we positioned the civics 4cyl into the v6 accord and offered it for the 4 cylinder value. so in return we in straightforward terms spent approximately 2 grand in procuring each and every of the stuff we could desire to do the replace.

Might be best to find an old school bus in a junk yard or auction yard.
