Pretty much spent the weekend repairing fences so I was only able to sneak one test in. 

I expected the HL-375A racing carb to post a big number. I just did not expect it to go off my calibration scale.

It flowed 105 CFM which is more than double a stock HL-173A.

All my testing is per SAE J607, 3″ Hg pressure drop corrected to 29.92 Hg and 60° F.
