Well, continuing on the 4BT trajectory was going to be more money than I was willing to spend. I am going to cut my losses on the Cummins and part it out. I should be able to break even. To that end, I went shopping for a low mileage LS engine/transmission combo. For some reason, I couldn't find anything with less than 100k miles. I know one of those would have a lot of life left in it, but I want even more life. In my search, I stumbled across a 1995 LT1 5.7L and 4L60E out of a wrecked Buick Roadmaster with just 48K on it. I have changed plugs, plug wires, opti-spark cap and rotor and water pump. Now I am paring down the wiring harness to eliminate the unnecessary junk. I have sent off the PCM for a reflash to eliminate much of the emissions stuff and change the final drive ratio parameters.
Now I am regretting swapping my automatic steering column for a floor shift manual one!
