Reply to "Building an economical 351C"

I have an Edelbrock Performer 4V an a Holley 600CFM with vacuum secondaries. This is an 1850 though I've change the secondaries from a metering plate to a jet block so I can change the jetting. I have 64 primaries and 66 (maybe 68) secondaries.
I get less than 10mpg regardless of how fast or slow I drive. A short afternoon cruise of say 100 miles costs me $70, which is a lot of beer.

I'm heading the rolling road for some diagnostics as soon as I got some spare cash because there may be something wrong that I have yet to find.

I've noticed that the UK magazines quote the standard GTS at 13-14mpg imperial which is 10.8 to 11.6mpg US which isn't much better than I get, hence the question.

I was thinking about manifolds, timing, vacuum advance distributor, porting, cam etc. My ass hasn't got the hang of Ford V8's yet it's still calibrated for Sunbeam engines.
