Bill, would a MAF from a Chevy 4.3 work also?

I'm sure it would Mike, not sure..I think it'* smaller than our stock accordian tubing though.

Darn it, wife just left with our Blazer. I'll measure the diameter when she gets back.

That'* the same MAF that the 3100, 3400, and 3.5L Shortstar use. It'* a 3", or so, and is smaller than the LQ4 MAF people choose. If you go to a N* TB, around 3.75-4", you wouldn't have happy airflow with that smaller MAF sensor.

And Bill, they're generally of similar displacement - 5 - 6L. The LS3 is a 6.0.

Since I've got one sitting outside right now, I went and got a measurement for you guys. It'* 3.25" in diameter.
