Hello Mr. Johnson,
Above is an excellent document Chris put together on the subject.
I haven’t used one of the vehicles so I can’t advise from any personal experience but in short I would look for a high horsepower to weight ratio , plenty of room under the truck and also under the hood. Be aware of plastic intake manifold or any sensors that a fire in the intake manifold would ruin. Can the fuel pump be variable controlled , can the fuel injectors be run dry without damage , Will the computer advance the timing high enough or can it be manually advanced . Does your state have vehicle inspections that might be failed by a computer code.
