I would go ahead and do the 100mm. That'll eliminate the possible regret of possibly picking up some power. Just make sure you've got a good tuner. They say they're a little harder to tune. I actually made a 100mm maf sensor. 50 bucks for a LS7 style sensor, 25 for the harness, 30ish for the maf housing with bung attached, and like 10 or so for a honeycomb.
I recently went SD and am going back to MAF. At WOT the MAF just plain old gives a more stable AFR. I run the 100mm LS3 style card MAF. What I did was screen the 100mm MAF. Going down the road I get 102kpa at WOT. It's not a dense screen like stock. Maybe 6-8 cells per sq in.
With a 383 you should certainly go with the bigger MAF. It's not hard to tune at all. I did it and I am certainly not a pro tuner by any stretch. I have a solid 12.8AFR from 2500-6700. The MAF is the easiest thing in the ECU to tune by far. (personal opinion)
