Oh yeah
The distributor has a mechanical advance internally. You can add a vacuum advance later if you think you need it.
The ignition timing mark is on the flywheel, it can be seen through a hole in the bell housing just above the starter. There is a pointer there also.
A quick way to find timing marks is, pull number one spark plug (with ignition "OFF") place you finger over the spark plug hole and rotate engine until you feel the compression for number one. Then slowly crank it over by hand till you see the marks.
This usually takes several tries to get it right.
Or crawl under the truck pull the flywheel dust cover, rotate the flywheel until you see the marks...I paint mine white.
Dance like no one is watching,
Sing like no one is listening,
Love like you've never been hurt.
