Sounds like its way too late for that advice...

Is it your daily? If not, why worry about it? If it is, then I can understand, and would buy a beater to drive daily.

Im heading out to look at 70 3/4 ton in about 15 min. Its a manual steering truck and would like to know if I can add power steering to it with out any frame modifications? YES I am regretting selling my first 70 but now have a new plan. I will post pics if she comes home with me.

I know exactly how you feel. I bought my truck with a 68 396 in it in 2001. The price of gas wasn't bad in 2001 but by 2005/2006 it started to get nuts. I only use the truck in the summer ( April/May through Sept/Oct ) and thought of getting a 700R4 but that conversion would be about 3000.00 to do properly. So to gain 2 or 3 mpg it wouldn't be worth it to spend 3000 on the the conversion. With you living in Illinois I'm sure you won't be driving your truck in the Winter months either. After all the work you have done on the truck drive it to enjoy it and get yourself a commuter vehicle. Pick up an old Crown Vic cop car from police auction and commute with that. They are tough as nails and cheap to fix and you can run them 3,4, 500,000 miles before they die. Around here 2008,2009 and 2010 ex-cop Crown Vics go for 900.00 to 16/1700 at the auction. The unmarked ones usually bring a few more bucks if you don't want to drive a black and white.

Looks like I own it. I will pick it up tomorrow night after work.

I get 10-12 city/hwy mpg. Buddy with same teanny rear gear with a sbc 350 about same hp/tq ratings get 14-16 mpg. I like my bb,,,don't change it out. You may regret it later.

adding vacuum advance is sure to improve your mileage.

I plan on installing a 200-4R behind my BB first. If that doesn't improve the mileage, I'll just install a 600HP Buick Grand National turbocharged V6 that's in my 78 Malibu. That should wake the truck up and get great gas mileage. Turbocharging and small engines make gobs of torque and get good mileage. It's the fact that most people think *bigger is better*. My Malibu gets about 24mpg and makes 600 rear wheel horsepower.
