On my 79 Chevrolet the vac gage acted like an mpg meter It got so as I could predict the mpg based on what the # of inmg vac had ben doing for the last 2 hrs . Hold it down at 7inmg you got 7mpg (85-90mph) holdit up at 14 inmg and you got 14mph (55-70mph). Get behind a truck and watch it pick up 3-5inmg. Pulling a grade I'd try to maintain 7.5inmg because my Edelbrock carburetor had the 7inmg enrichment springs.
Z---
As a side note when I put the MSD in I was able to switch from premium to bace grade . This improved my bottom dollar by 20-40cents per ga.+ a healthy bump on the amount of fuel consumption .
So bottom line. Proformance parts sold to hard core racers ,installed in place of stock parts, helped my cost of operations aka economy. By improving the efficiency of my approximately 400hp 350ci.
