You are going to stroke on this one. I drive 50 hard miles one way to work. Generally 40 of it are country/hwy 4lane. The last 10 are in the city. I travel at or above 75 on the hwy. I get 21/22 usually. My last race I drove 146 miles round trip to the track. Made 13 passes on the 1/8th mile track. Most of which were 8.30's (full 1/8th at 84mph). I got 21mpg round trip. On that cruise I usually get 26-27.9 maximum but travel only 55-65mph (filling up at the trackside). I have 3.55's and the car is 3127 with me in it. 351 heads, 19lb injectors and an EEC tuner with A9L EEC. Figure that one out. My last good v8 stang was a Stock 89 with 3.08 gears and never got over 23 or so and I treated it as if it were a hurse. My EEC tuner is set for a little leaner tune (hwy) but before this I was getting nearly the same mileage on it before the head/intake swap. Before I could muster an 8.80 on the stock engine. The engine came out of a stock 88gt with 99K miles showing when it was wrecked. The plug wires were 88 vintage as well as needing oil pan and valve cover gaskets. It will smoke decently on a 75 shot to show it's age. This car is an 83 fox coupe converted to mass air EFI from an 89. Talk about a builder.
