What does it take to convert a LB7 to a LLY or LBZ? I'm talking about a 03 model.

That's a pretty vague question. Do you want to just change the short block or do a long block swap?

I'm sure some others on here can and will lend some advice but I know Rick Lance (the one that builds the headers) has done this so I would recommend contacting him about some info. I'm pretty sure he had a pretty in depth thread about it over on DieselPlace also.


Good luck
