And before you spend your money on a used engine that you're going to have to rebuild, do yourself a favor and shop the deals on 350 crate engines. These shops buy parts in bulk at prices you can't come near, and they apply a markup to the overall engine as opposed to marking up all the pieces & parts, and then adding in a healthy labor charge. It's likely you can buy a complete crate engine cheaper than you can build one yourself, and many of the reputable places offer a warranty that is almost like a new car. Now if you can pick up a late model, low mileage takeout engine that doesn't need anything that's another story.... And welcome to CHR, by the way.
