I have a 2wd I had heard about this problem long before I posted this and I have a C6 conversion waiting, I'm glad I have the 2wd. apparently the C6 pan wont fit on 4wd. I was thinking a Procharger or a Maggie for boost unless anyone can tell me why I shouldn't. I haven't heard anything bad about them. I was also looking at getting rid of the clutch fan anyways. I assume a junkyard 80e with a rebuild will suffice? Any suggestions on what stall I should go with to keep good drivability? I wanted to lower it about 2" or so as well as get of the airbags completely.
