What quantity am i getting? what does "3x1/5q" in the title description mean?

5 quarts. I don't know what 3x1/ means, but it's 5 quarts. You can see it on the label in the picture.

can i use this on 1975 chevy k20 pickup truck w/400 small block? mostly cruising around town

The main reason I use this oil product is because it meets/exceeds the zinc additive levels required for the flat tappet cam on my GM 327 V8. The engine is very happy with it and oil changes show exceptional wearability. That said, you'll want to conduct your own evaluations of oil products for your engine application.

Can use this in a 67-68. Chevy 350 engine for my 59 chevy truck?

Yes, that engine needs zinc. Flat tappet

Is this full synthetic?

If you just take the time to read it all.. Lucas oil for Hot Rods & Muscle cars is recommended for most engines from the 50s,60s &70s that were designed to use a conventional oil like what was available back then...It has additives like zinc that are not found in today's oils & therefore,it is NOT compatable with any cars with catalatic converters,(emissions controll system) & No,it is not a synthetic oil, it is conventional, which means it is petroleum based.
