These MPG are great, Been a LONG time since I had my 67 (230c/I) sixer' they sound correct.
Sold mine in 1984.  Economy with style.

Had a 67 convertible, stock 250ci with powerglide and it got the same as my 68's 327 thats pumped up a little. around 12-14 mpg around town on a good day. One of the reasons the car was sold.
