New to mechanics is fine and so is to these specific models. To get up to speed (I hada read just to know what Qs to ask) is The Ford Six Performance Handbook. Many get it from Matt at vintage inlined dot com (25$?). While waiting for delivery peruse the (Classic Inlines) tech archive @ above crossed screwdriver/wrench.
After gettin 'the Handbook' my suggestion is "to ID whaja got". After 54 yrs of multiple owners U can't trust that all parts R '65 stang. At least ID the head, block, rear end, ingit system (dizzy, coil, etc),carb and other upgradable prts. The handbook shows engine, transmis components. Some times pretty subtle differences but performance effects (pep'n MPGs).
If U have the willingness & patience - we got the knowledge.
Think ur into maintenance only? daily driver? performance improvements? machining?
We can even recommend tools to acquire for each if interested.
