pollution controls?

I'm getting about 20 average, ranging from 20 - 23 so far. No emmissions stuff (L28 with e.f.i "doesn't need emmissions stuff"). I took off the EGR last summer and I'm going to fix up what's left to look nicer and work better.

FWIW

I would guess with your motor build, SUs with SMs, sounds like the ball park-17 to 22. But then again, does your right foot have a mind of it's own and often enjoy the pedal to the metal? drive it like you stole it? or rather like an old lady? :nervous:

The 77 gets gallons per mile rather than miles per gallon . I never really thought of the Z car as a gas saver, so to speak, even back in the 70's. Now, I'm not comparing the car to 70's V-8's but how did the Z match up to other vehicles of simular (I know, I know, there's none to us) class back then?

Triumphs, TVR's, The pitiful Mustang II, etc.

Exactly, how can you even think about mileage when you have such a fun car to drive as a Z. On the gas, going through the gears, off the gas, back-fire, back-fire, rumble rumble, then on the gas again.

Hmm, sounds like music with a repeating chorus to me!

And there is no gas mileage in that song...

I rebuilt an 81 F54 (new rings & bearings) and matched that up with an early E88 head with the bigger N42 valves, am using triple Mikuni 44 PHH carbs, and am getting almost 25MPG on the freeway - not much less around town.

That's why I have a fuel-efficient Ford Escort that gets 30+ MPG for those LONG trips where the fuel depots are 100 miles apart!
