Diesel Particulate Filter

[Lowered13]

Hello I am looking for some information. I am looking into swapping a diesel engine into a 67-72 Chevy c10 and narrowed it down to an lbz or an Ecodiesel. I am wanting the ability to run b100 though the engine and I know that you can't with the Ecodiesel because of the particulate filter. What I am wondering is that if I were to swap in the Ecodiesel would I have to install the diesel particulate filter to comply with regulations or do the regulations apply to the truck itself and not the engine installed? I know if there was no particulate filter that I would need to reprogram it, just need to know if I can even do it legally.
Thankyou for the help in advance.
