    408 NA MAF? 90mm or 100mm?

    So here is my ? I have a 408 w/ l76 intake man. I have already sourced a cheap gm big truck maf 89mm i.d (they refer to it as 85). Should I just stick with this and spend the cash elsewhere, or should I get a 100mm maf? I have a fast toys lid (98mm i.d) and a 90mm tb. From what I have read/ heard I should be fine with my current maf, Oh and I want to decide this before I go get it dyno'd for obvious reasons ($$) so I dont have to go back. And speed density has already been ruled out.
