It only has about 80,000 original miles and I think that I got about 15 mpg when I first got it on a trip up into northern Washington state with steady driving about 60 miles per hour. I wouldn't count on getting that much though.

I have considered getting an O/D transmission and several years ago, I found a link to a company in Canada that made an O/D that would bolt up to an FE block and if I remember correctly, it cost about $2,500 to $3,000. I don't know if they are still making them though.

I do have one question that maybe someone on the list could answer. I currently need to rebuild the 390 and I understand that they are fairly expensive to rebuild and I was wondering if someone has recently rebuilt one and approximately what the rebuild cost?

Also, when I do rebuild it, I am thinking of putting in a mild cam for towing to increase the power a little. Any thoughts would be appreciated.

At the present price of gas, I can't afford to drive it much, but it is my back up truck and if I need to pull a heavy load, it does serve well.

Thanks for any inputs. norseman
