should be between .017" and .021"
I believe that's .017 point gap with the automatic transmission equipped 390
A 1968 Ford Galaxie 500 with a 390 engine should use a spark plug such as an E3 brand spark plug. This plug should have a tapered seat with 18mm threads.
.017
I BELIEVE the point gap is ( .017 ) and point dwell is ( 26 - 31 )
With a wrench..7-8 open end.

In the film Bullitt (1968), Steve McQueen drives a Highland Green, 1968 Ford Mustang GT 390 fastback.
1968 Ford Mustang GT 390
Ford made 50,045 xl fastbacks and there was only 1855 gts built which included convertibles and the smallest engine was a z code 390 v 4 but i don't know how many were fastbacks only
It depends on the specific sub model you are talking about. The 1968 Ford Mustang Hardtop 390 Thunderbird Special V-8 4-speed with 325 HP has a top speed of 212 km/h (132 mph. While the 1968 Ford Mustang Hardtop 390 Thunderbird Special V-8 Cruise-O-Matic with 325 HP has a top speed of 208 km/h (129 mph). There is no 324 HP variation for the 1968 model.
Ford just refers to it as the 390 but it would be ( around 6.4 liters )
