69-73 460 gap is .034" 74 is .054, 75 model gap is .044
The point gap for the big block (390/428) Ford in 1969 would be .017". The 460 is also ,017 according to an old Chilton book for a 1973 Ford Thunderbird 460 cubic inch.
For a 1969 Lincoln, the point gap is set at .017, and the spark gap should be set at .035.
Dist. Points gap is .016" (0.4mm)
New points, .019"Used points, .016"
I was looking at one of the Ford websites and it shows : For a ( 1978 ) Lincoln Mark V , 7.5 litre / 460 cubic inch ( the spark plugs are gapped at .050 inch )
Typically around 28-32 degrees
The gap for the 460 is .042-.046, I had a 1991 should be the same 99.9% sure.
.044
If it has points in the distributor then it is 0.035 If it has an HEI distributor then it is 0.045
