( .035 inch ) is the spark plug gap
I BELIEVE the point gap is ( .017 ) and point dwell is ( 26 - 31 )
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.
I believe that's .017 point gap with the automatic transmission equipped 390
Ford uses Motorcraft Spark plugs on all there vehicles.
With a wrench..7-8 open end.
bad
It will serve the purpose and may fit perfectly or you may have to do a little modification.
No the 390 is a big block the 302 is a small block.
About 10 to 14 mpg
Counting the one in my garage.... 1.5
