R&D: Anything from 0 here take it to what you can afford. There is a blue million out there! We (me and my boys) would buy an old car use it for the demolition derby keep the 350's junk the rest.
I have $700.00 in the one I'm putting in my 59. Its totally overhauled short block w/ core exchange. Finishing the rest myself. popcorn The Truth is Out There (Start looking for an older couple that has a old car with one in it, try to deal) Salvaage yards are all right if they will give you pastowners name or history.
