If you have 2.8 or 3.1 questions honestly this ain't the site for you.
Theres a community for 2.8 MPFI/3.1 MPFI/3.4 DOHC/3100 SFI/3400 SFI... etc etc, basically 60 degree V6 guys. Go here: The BEST Source For All Your GM 60ºV6 Needs , the guys over there will help you out. Ben Phelps and I started that board years ago since there was NOTHING out there for those motors/cars. I'm a former 3.1 MPFI guy myself (had a 1993 GP SE)
Anyway, there is a good group of people over there that would be happy to help you out with whatever you need. Great community over there... Hope this helps.
