Hi Zack,
Tim yesterday, and David Stoker this morning asked me to get you my before and after gas-mileage figures. I dug through my records from the month I drove the truck with the Turbo Hydro 350, and then on Americruise with the Gearstar 4L60E. Off the top I can tell you I picked up about 2-3 MPG overall from stock (as high as 18 MPG). This was compiled from 5,200 miles of highway, and some city driving. Bear in mind that my truck has 3.07:1 gears so it is only turning 2050 RPM at 80 MPH. Another thing that helped the gas-mileage by doing the 4L60E conversion was I picked up a lower first gear so now the truck is quicker off-the-line, and my city mileage improved. After almost 15,000 miles of extreme abuse the 350 engine in my '79 has developed some bad oil leaks, and terrible knocking sounds as well. In the near future I'm going to pull the 350 out, and plug-in a late 5.3 junkyard motor behind the Gearstar 4L60E. Getting much better gas-mileage is the key to survival for these old trucks. From the very start I've had my sights on over 20 MPG for this truck. I'll keep you posted as the swap progresses.
Thanks again for providing me with a bulletproof transmission!
Best,
John Gilbert, Editor
