So I got a 93 k3500 with a mechanical 6.5. My injection pump head is toast so i am looking out there and find pumps of all prices. The question is which one should I get? I got my eye on the kennedy marine pump but after poking around on here it sounds like I might not have my rig setup for that yet nor it being the best option for a truck. I am replacing my head gasket and putting arp head studs in. The turbo was the next item I was going to up grade. I got the oem turbo doing about 15-17 psi right now. Some advice on this would be much appreciated before spending over a grand on this.
