72 1010 auto 392 w/ac.

This thing hasn't been started inyears and am rehabbing. Should I sitck with a stock 16# cap or go lower to like 13 or 7?

Two lines of thought here, on one hand if you're not going to be working it hard, it'll probably be fine with a 7# cap. However if you want to be sure it can be depended on a system in good repair a the stock 16# will assist you in detecting any weak areas of the cooling system that need attention.
