My truck has a 8.1 out of a 2500 silverado, modern fuel injection but stand alone engine harness thats simple enough that it can be fixed. If anything ever happens to this motor it will be replaced with a low milage cummins diesel i have stashed away.They make some very reliable v8's nowadays, but applying the KISS principle and keeping the extraneous electrojunk to a minimum would be sweet. I'd take a fuel injected modern V8 over the old carbureted mess they had in those machines. Dont get me wrong they are reliable, but modern engines are better in every possible way.
