TX9 Tuxedo Black 1966 Charger, congrats
& good luck
what's the plan ?
an OE style resto ?
or a mild custom/day 2 car ?
or full on, performance build ?
since it doesn't have the matching #'s engine,
skies the limit, big block 383 or 440, Hemi is pricey
(I would personally keep it the org. TX9 Tuxedo Black, if it was mine,
the rest is personal choice, I'd do a Big Block, with a nice free flowing exhaust system
alum. good intake & nice performance carb (Holley), some nice wider wheels & tires,
some good disc brakes (upgrade if need be), go fully thru all the electrical to start,
especially the 'firewall bulkhead connectors/cleaned or replaced' (problems on these old cars),
under-dash wiring, for safety 1st, hopefully it was NOT invaded by mice/other pests)
have fun that's the best plan,
build it how you want it
safety stuff 1st, is a great idea,
just plan ahead, you don't need to buy stuff twice,
make an outline or a plan & stick to it
Budget, you personal skill level & tools, usually dictates what type of project
