So I'm looking at doing a smog legal Chevy swap, and I really do want to get it reffed. As far as I can tell, its going to be a b**** and a half to get an LS1 swap certified, but a pre-OBD II LT1 swap shouldn't be nearly as bad, right? Has anyone gone through the ref process with either? I want to be sure that the relative ease of the LT1 is truly worth the performance loss. Additionally, for you smog-legal guys, how did you deal with headers? Technically you need the stock Camaro headers, but I'm fairly sure that didn't happen, so how did you deal with that?
