mass air and throttle body

MAM or MAF call it what you will, but they still do the same thing. And they is no special measuring system, use a f u c k i n g ruler or some di-calipers, what ever, just measure the smaller end.

Also, bigger is not always better, like mlambrecht82 said. Look at what the old 5 liters came with, 60mm TB and a 55mm MAF, and they still would put down some very decent numbers stock. Now that's on a 302, now we are down to a smaller CI engine, only 281 CI. How much more airflow do you think this smaller engine needs??? Sure go ahead and put a 90mm MAF or whatever, and you might pick up some HP, but all on the top end, and you'll also lose some on bottom end. This is kind of like putting a dominator on a stock 302, sure if it's tuned right it'll run good, but it's overkill. Do you see what I'm saying???

And yes, the stock MAF on my 1996 GTS/248a is 80mm.
