Re: MPG poll
I'm supposed to say "BS", but you have a Cummins and O/D. So it's, "BS. It's not better than that? When's the last time you changed your plugs?"

Re: MPG poll
I was so disappointed that after installing a Blueprint 383 and 700r4 that I could barely manage 8 mpg! Even using just 3rd and not OD it didn't improve much as I think the engine just isn't operating efficiently at such low rpm. I still had the 3.07 gears so, as soon as my buddy has room at his shop the new yukon dura grip carrier and 3.73 gears are going in. I hope it helps! If nothing else it'll be more smiles to the gallon!

Re: MPG poll
I had a 327 rebuilt at a local machine shop. I had it installed by another shop. After I got it back and ran it through the paces of breaking in a "newly" machined motor, I was shocked that I was only getting 8MPG. It did take a little while to fully break in that motor as it is my daily driver but it gets a solid 13 or so MPG every week. Not the greatest for sure but it does ok for me now.
327, 3 speed manual, 3:73 to 1 rear end gears.

Re: MPG poll
It has enough fuel for 2 engines is part of that issue. But it does have 2 spinny mufflers.

In 3rd with your present 3.07’s your 383 doesn’t like 2400 rpm at 65mph. In third with 3.73’s it’ll be 2900 rpm. Much better. In o/d you’ll be worse off at 2100 rpm. At least you’ll have smiles per gallon! |
