Single or double?

with the 360 timing cover you won't be able to see the timing marks-- or just barely, if you can. it also exits on the DS.

the key is that it all has to work as a system, otherwise you wind up with a kludged together mess.

if i was in your position i'd look at something 70+ so it's pass side pump & radiator, and the upper will be skewed toward the DS so there's no interference with the fan. sourcing a shroud and clutch fan (or electric fan) would be cheaper and easier with that type of radiator.

I run a '70 up timing cover with a '68 and earlier timing tab bolted to pass side. Then I cut a new groove in balancer for zero degrees on pass side. So the '70 up timing cover can be made to work on cast iron water pump cars.

'69 was only year timing marks were cast on pass side a one year only thing. '68 and earlier a bolt on tab was used on pass side.
