my daily driven '68 LWB 5.3/4l60e

Very cool sleeper - even better since you have all the original paperwork. I used to live over in Fort Smith myself. There are 3 or 4 of us on the board from the Little Rock area too.

Next on my list of "to do's" is to put the original accelerator pedal in and make it work with the dbw throttle body. I think it will be neat to have the floor mounted pedal with dbw and cruise control. The cruise works great.....use it nearly everyday on the interstate when going to work.

Can you give details on your cruise setup? What handle did you use? What all is involved?

I used a factory headlight switch......you can see it in one of my interior pictures. Its in the factory manual choke location. Its kinda lame if you're into chrome and billet, but my requirements were to keep it factory appearing. I wired it so that pulling the switch out, like the headlights are on, enables the cruise. To engage the cruise you rotate the dimmer part of the switch. The dbw setup on the genIII tac module has everything you need. I didn't bother with an accel switch, it wasn't that important to me. The lame part is that the tac module needs to see a high to low transition for the engage input, so you you have to rotate the dimmer switch towards the on position then back to the off position. The dimmer is just a potentiometer, so you only have to rotate enough to generate the correct voltage for the input and then back. It works well and is safe. You have to have the switch pulled out to use it and the tac module has an input for the brake switch. I did have to use a relay to get a normally closed contact. I'd like to put a small torsional spring on the dimmer part of the switch so that it will spring back and feel a little better.

Sweet truck, I like the stock appearance and patina. What did you use for radiator and fans? I'm in the process of rounding up parts to put a 4.8/4l60e in my 67. I got both engine and trans with 60,000 miles for $750 and the 20 horsepower difference didn't seem like that big a deal for the price.

I used a radiator from a '95 silverado with a 4.3 v6 and the factory 5.3 clutch fan. I finished this swap 3 years ago and wanted to do it with parts that could be bought at the local parts stores , so the radiator just made sense. The hoses are the factory 5.3 hoses....I had to cut the lower hose a little shorter, but they worked well.
