Hello wore out I have a 93 3406 cat and the peec system is giving trouble. On rare occasions it fires right up then most days it cranks over forever then will eventually crank if I mess with it long enough. I am thinking about having it converted to a mechanical pump. The engine is a 4CK11717. So does that make it a B with peec or a C with peec and what mechanical pump would work on this truck? The pump on it now is a 7E5888. Any help would be appreciated.

It will work great with the 8789's and 14.6 steel topps. Your gonna want an 80/1:45. Set timing to 21@1000rpms start screw @1450 and 31-32° @1000rpms. May require a degree or 2 more to clean up any excessive smoke. Will run clean and make 700or so hp with rack maxxed mybe more if you put in a 4p-0998 18° cam in your fuel pump if you have a 7e-5888 dual scroll pump.
