Are you sure about that? I had read that you could not. I have one, and if you can use one, I may get the MAF translator, and extender chip, but if not, I dont know what I will do.
I pulled the 3.5" MAF off my 97 WS6 LT1 and put it on my Buick w/ translator. Works great. Been on there for 3 or 4 years....no problems. I thought I had a MAF problem on the LT1, turned out to be other, so I had an extra. LT1 3.5" WILL work.
