Is a used Vortec swap (LS) out of the question? LQ4's and LQ9's, among others can be found relatively easily online and really are not all that difficult to install. Plenty torque, good mileage, start every time you turn the key . . . You may even find someone willing to offer a warranty. I did my own, found a 6.0 LQ4 complete (harness, computer, accessories) for $700.00. Followed a web site online step by step, and viola - modern engine in an older truck. Just a thought.
