They will pull a load and laugh doing it. They are pretty easy to build power with compared to all the later computer controlled engines.

Yeah swapping a diesel would be sick but a lot of money lol and I just finish this ls swap like 3 months ago but i think if this motor dies then the 5.9 will be next to replace it but I heard there kind of a pain to fit? do you have to cut into the firewall? or does it fit in the engine bay just snug.
