I’ve searched for days every where about a v6 to v8 swap for the nnbs and can’t find anything i keep finding the nbs 99-06. Also read something about fpcm on newer trucks

I have a nnbs 07 v6. What I want to know is the swap basically the same has the 99-06. I no I need to use a v8 from 07 our newer cause of the reluctor wheel. If I got a 07 an up engine and harness what else I need I no they say the ecu can be tuned for it.

I found a complete driving 08 3500 series 6.0 6l90e wondering if I just took everything harness tcm ecu cluster shifter pedal assembly. If that swap is possible.

Our just want a simple v8 5.3 4.8 i no I have to deal with the dod afm. I just need some help on if I can pick up a 07-10 ish motor with a harness and all of that’s all I need besides all the other stuff I read I have to deal with. Say I got a complete 6.2 with everything can I just swap it all to our that’s more involved

Also going to do a 4l80e gonna use a harness to make it simpler for me. I no all the stuff I need for that swap. Using the tcm from a 4.8 2500 series Chevy express.

since the cargo vans 07-08 come with 4.8 4l80e can use use the entire swap. Without needing to re wire pin harness and buy adapter harness?

I’m guessing I’ll have to buy hp tuner. Would it still all need programming if I swap everything any idea if I have to do the gas pedal to since it’s electric
