Going racing + dyno tomorrow. Predictions?

Your Duster will definitely be WAY cooler than anything from the late 90's-2000's....I'm just sayin.....no belly button cars for me thanks.

I have the duster because i completely felt the same way, but non-belly button cars are expensive and have annoying pitfalls.

Though looking at that chart, i do wonder if #3 or #25 would be more advisable in richening the WOT and giving the car better cruise manners.

That's where I would head. I'd try to get your cruise closer to 14:1

Maybe turn the timing up a few degrees. It may like the additional initial timing. As long as it starts OK when warm, run it. Adding timing will likely clean up your AF's too.

There's no reason you shouldn't get 15+mpg on the highway, maybe even closer to 20. That purple car got 20-21 on the highway with the 2.7-2.9 gears.

Well i'll hopefully report back in a few hours. since gas will be effed here in california for a few weeks i took down my CL ad.(the 6dr caddy limo guy will be crushed) Worse comes to worse, it'll be back up in a few weeks when gas is down to its "reasonable" 3.90-4.00 a gallon.

I could stand this car if it could do 65 and get 15-20 without overdrive/efi, but i'm not so confident in that happening. With my converter slip on the hwy it tach's 3k or so at 65mph.
