Not sure about this. Does the engine Vin# have to match the factory ECU? Is the engine you put in a '97 also? I know on some vehicles this makes a difference. You may want to call a Chevy dealer.

What year 5.7 did you get?

I found the problem, i had a short in the wiring harness, but when I did the truck started it dropped a valve in #7 cylinder, so back to square one.
