Gas Mileage you wont believe this...
 

I drove my 78Z with a K&N Intake 21/2 straight exhaust no cat with a mini turbo muffler. I am running 235/60-14 Tires. I averaged about 85MPH and got 27MPG. I find this extremely awesome. My Honda Civic only gets 33 doing 75MPH. Just wanted to share this with you all.

what can i say, datsun is the only way to travel!

"any car can get you where you need to go, but a special car gets you there with a smile on your face!" mr. k was right, and, if that means traveling fast, all the better!

Wow - excellent mileage. Best I ever got out of my '77 was 23 mpg with the L28. Now I've got an LS1 and it get 25-26.
