Timing Chain 1977 dodge van

[Jowseftayler]

I was wondering whether or not I should get a double roller or a single roller timing chain.

If you plan on keeping the van and the rest of the engine is in good condition I would go with a double roller chain... It will last longer.
What ever you do, don't use the cheapest replacement that has a nylon/aluminium cam gear. They cause problems when they break apart.
