My Dart Swinger Project!

Nothing wrong with going forward with what you have, but it might make more sense to sell all that you have. To bore, hone, and assemble, you'll be way over the amount it cost to buy a good running motor - that you heard run yourself, not one that they say ran good. Or, a Good running 318/360 magnum can be had for 350 bucks from a reputable salvage yard.
