Can somebody please direct me to posted tune-up specs for my 1974 F250 390 2v with automatic trans? I've searched the net for several hours and can't find this info. I have a service manual for 1971 but don't know if the specs were the same for 1974.

For 1971, they were:
Dwell at idle- 26-31
Point gap- 0.017
Plug gap- 0.032-0.036
Plug- BF32
Timing- 6 degrees BTC with vacuum line off and plugged

Carb#- D1TF-AKA
Idle 550 RPM
Fast idle 1500 RPM

Thanks

 

They usually say to look at the decal on the valve cover.

Here's mine up until 72.
