Hands down 6.0LS with 4L80 E and never look back. Old school is fine but if you want to drive the truck on long trips nothing will touch the LS. NOTHING even the BB want match the power and the gas milage.

I just got home from a 1800 mile trip in my 71 with 6.0 and 4:10 gears it was nice.
Don't get into the electronic stuff to deep. The computer doesn't need the truck dash gauges to run it.

GPS speedometer is the best and easy way. Speedhut.com is what I have and they are great.

Get you a scan gauge 2 also it plugs into the ECU and you have any info you need plus it will erase codes if you need it to. That's the water temp 177*, trans temp 179* with no fans running while moving, volts and closed loop.

My 71 ran 9hrs coming home from Mississippi Tuesday running 80MPH 2400 RPM's with AC on. Pictures are worth 1000 words. It was 85* outside that day. 15 MPG want no BB do that!

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811.
