Easiest and cheapest motor will be the Chevy small block as Wrench said. You might find something else cheaper to buy but it won't be cheaper to install and maintain.

The question is can you get something new enough it doesn't need to be rebuilt without needing to install a computer to run it. Rather than shopping used you might investigate buying a crate motor. The cheap Chevy crate motors don't cost much and are intended to run a carb and distributor instead of a computer.

Of course if setting up a computer to run your motor doesn't bother you, there are lots of options out there.
