Re: mpg (hubes)
Most of the time around the city, I am getting about 10-12 mpg. Just recently got back from 2500 mile trip ( Stars & Stripes Tour) and got about 14- 15 out on the road. My '75 is original engine (350 ci, L-82) and has about 63,000 miles on it.
Your mpg will depend on what year yours is. I have seen this posted before and seems like 80-82's get better mileage (20-25) and most earlier C3's get about what I am getting. Anywhere between 7 mpg to 15 mpg.

Re: mpg (lbell101)
lbell101,
I love the photos in your signature. The car looks great going that fast. Only problem is - how did you take the photo with the car going that fast without a driver? :D
No seriously, the photo is great. How did you get that effect?

Re: mpg (Rich's75)
Hey Rich...thanks!
Actually, it's pretty easy. Just select the area around the car and use the Wind Deformation function in Paint Shop Pro. It's not my original idea, I copied what some other members had already done!

The L88 is a big block with very long duration cam which doesn't make for the best mileage. A more modest cam would give much higher mileage. Overall gearing is 2.53:1

Re: mpg (hubes)
The 69 350 with 373's is getting 14-15 mpg combo driving. That's cruising 40mph@2000 rpm, and 70-75 mph @ 3100-3300 rpm!
Runs on 89 octane fine. I ownder what it will do when I put a xe268 and Torquer heads on?

Re: mpg (hubes)
I'd say about 8 in the city, never been on the highway, but that's with a lot of moderate to heavy throttle :D . As soon as I get my new speedo/odometer cable installed I'll be able to exactly what I'm getting.

Re: mpg (hubes)
I was getting 16mph on my way back from Iola, haven't used a tank in the city to find out for that. Probably better than highway since I was at about 3200rpm and I don't rev that high in the city unless there aren't any cars around. Might be the same now that I am starting to get used to the power.
