65 dart small block

I sold the 440/727, to buy disc breaks for the front of my 65 dart gt /6. they should be coming by ups in a couple of days. the old 213k mile slant is going to be retired soon for some small block power. i think i want to go with a remaned 360, or even a low mile one, and want to put in a 513 lift cam, headers, 4 barrel, and other goodies. (for a daily driver) im new to mopar, how would be the cheapest way to get screamin small block power out of this 43 year old beast?
