Default Which one C&L 73mm or 76mm?

I am looking into buying a new MAF for my 91 GT. Which is better for a near stock motor? The 73mm or the new 76mm?

IMO, as long as you don't go bigger than your MAF with your TB size, you'll be fine.

you mean your tb should be smaller than maf right? im going 73mm which is good for n/a correct? i have a 65 mm tb now, and still retain stock maf, i saw no gain with my tb so far, heads are coming soon, along with a 73 vortech housing, that should put me in 12's im hoping.

The 73mm was the older design. Any brand new C&L or Vortec housing will be a 76mm unit. You can't really go too large in a MAF in theroy. You can go too small and it's probably cheaper just to stock one size for up to 75 mm TB's
