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.
1968 Ford Mustang GT 390 CID Fastback
.019 new points. .017 used points.
1968 Ford Mustang GT 390
In the film Bullitt (1968), Steve McQueen drives a Highland Green, 1968 Ford Mustang GT 390 fastback.
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 )
