318 budget build help?

Thanks for the help guys! And yeah I know those words don't go together but it's just for the time being really. I keep telling myself "just get a 4 banger for gas and leave it alone" but every time I see or even think of a muscle/pony car I quickly regret even thinking that haha. Either way, there arnt many for sale over where I am at on cl and what not, however I have still yet to check the junkyards, so away to adventure I go!
