Slant Six mpg's?

Well, at least your honest in saying it was a 170 and not stock.

I love the 225 guys claims of 30+ in there rides, even more so in there trucks at 70+ mph and carrying 2 toms of heavy stuff on top of it.

Sorry fella's, I don't buy it and never will until you give a ride. And even then, unless I know you and trust you alot, I'll consider your "It's stock as a rock claim" invalid.

Looking foward to the day I'm proved wrong and until then, I just can not beileve a 225 / automatic is gonna get 30+ with a all stock car.

If you want accurate mpg readings, go over to the .org site and see what those guys have to say. You wont find many claiming anything over about 24mpg. You might have guys saying "I had my best run of __mpg doing 55 across the plains", but no one claiming to get 30 with a non Feather Duster...and especially not a truck.

Speaking of trucks, I just bought a 78 D100 with a super sixed 225 and 3 on the tree. Got 15mpg on the way home from where I bought it about 3 hours away. Looked under the hood a bit closer when I got home and noticed a ton of things not connected correctly. Going to be dropping in a 4 speed OD here when it gets warmer and also going to lower it a little bit so it doesn't sit like a turnip truck. We'll see what I can get. I'm hoping for 21mpg or so, which would be great for a truck. I'll have to post my results here after I finish the project.
