I searched the forum and web and couldnt find any info. Im considering selling my truck to get a nnbs, but want to know if the v6 to v8 swap procedure would be the same as a nbs. I havent kept myself up to date with the nnbs stuff.

I would get the engine with the correct reluctor wheel and put it in place of the 4.3 then get it tuned. Correct?

 

i never looked at the 4.3 so how is it set up?

id guess it'll be like the 99-07 classic.
get the motor, harnes, and MAYBE the ECM im not sure.

 

Thanks Keniff, im not sure I havent looked at one either. I expected to get the engine, harness and keep the ecm. Reason for this is I like doing this stuff and i can pick up a rcsb nnbs 4x4 6 cyl. a lot cheaper than one with an 8. Kinda hoping someone could tell me what all i need so i can see if its worth it to do the swap or buy a truck with an 8 already.

I would have thought someone on here has done the swap already?

 

how about this....go test drive the truck, take some pics of the motor/harness/ecm/fuse box for us lol.

 

lol I'll have to find one and do that I guess.

 

it cant be that hard to modify

 

Bump...ever do the swap OP or did anything come from this? trying to do some research on this swap with the search button instead of cluttering with new threads.
