Stock .318 upgrade!

I have a modified 1850, that once got over 30 mpg on my 367,
geared 65= 1600/ 85=2100. The Primaries worked awesome. At the end of the day tho, having reached my destination, I bolted the 750DP back on.

FYI
I have run the bigger Thermoquad on more than one totally stock long-block .318, to good effect. Well not totally stock, I ran one with Long-tube headers and full-length 3" dual-exhaust, lol..
With just a few adjustments, it ran great.
