Picked up a different truck a while ago. its a 1993 c3500 ext cab. i bought it with really band blowby. I rebuilt a 660 with promaxx heads and a wuhaun whistler , got it put in the truck and now i have the hot long crank to start. So I am looking for a new pump, I would like around 90cc of fueling. Who's using who ? Classic Diesel , Moose diesel ?
Thanks
Eric

If I was going to order a pump from any of the "bigger" IDI performance companies it would be from R&D. Justin doesn't advertise GM pumps on his website. But they are identical to 7.3 pumps so he can build them. I was going to have him build my pump on until I went overboard and decided to learn to to it my self.

I've spoken with Wes (CDD), Justin (R&D) and a few other pump builders over the past few years and they have all been super helpful. Unfortunately most of the good DB2 builders have retired. Moose (Conestoga) had a good builder that left a while back. Nate got lucky that he was still there to build his .330 pump. And I recently seen a few pictures of some of the internal parts that Wes was "modifying" to cut corners and save money on his 90cc pumps. So as much as I like the guy, after seeing that I cant support that kind of work.

I can build pumps but I'm at least a month out. I haven't fully set myself up for customer work so I have to order parts for each pump. Its expensive to sit on that kind of inventory when starting out. Plus I need the extra cash at the moment to get my truck done first.
