I got a question. so what are the laws reguarding putting a diesel in a gas truck, emmission wise? I mean, how would you pass emmisions in a state that checks? I talking mostly about AZ, where if it is 1996 or newer they hook up to the OBDII port? Would a 4bt be feasible(easy, cheap, legal, etc.) or is a 6.5L GM or some other engine more suitable, since the 6.5L was in half tons and was an OBDII engine?

I apologize if I am unclear, If you need me to, I can try to elaborate more. Thank you.

In a word, federal law prohibits tampering with any emissions controls, and most states that test prohibit any engine older than the chassis.

Best to check with local authorities and get their take on the issue before you start.
