Spark plug gap = 34
Point dwell = 24-29
Point gap = .021
Timing = 6* BTC
Idle speed = Std =650
auto = 550 Drv.

Until I can find some type of manual, I really need some basic settings for timing, plug gap, distributor, etc. Can someone please point me in the right direction.

Tune up specs
Correct-a-mundo for 1970 models. Prior to, and after, 1970 Ford listed these specs:
Plug gap: 34
Point gap/dwell: .017, 26-32
Timing: 6* BTDC, manual; 10* BTDC automatic
Curb idle speed: standard, 650 rpm in Neutral; auto, 550 rpm, in Drive, wheels chocked, brake set, headlights on.
When doing the timing, pull and plug vac advance hose at the distributor.
So, why the slight difference in specs? Only Ford knows for sure.
Either way will get your truck in the good running ballpark.
Good luck.
