The main reason I bought out costs is because when you upgrade the engine now you have to go right down the line, exhaust, transmission/converter, probably cross-member/driveshaft and rearend housing/type and don't forget the knick knacks. 🙂•》My most enjoyable cars were some of the cheaper builds. My opinion any more is have a fun/fairly fast street car or a drag strip only car. It's hard to have bought in one car. Your first priority is to check the bores in your block. That'll tell you if there is any possibility of re-using factory pistons. As you take it apart, number the pistons as to there bores. You'll find out your crankshaft condition also. Bag & tag your bolts/fasteners. Certain bolts are specific such as bolt that have a stud on the head aka one head bolt, one water pump bolt and don't loose any small spacers needed for accessory pulleys. Don't forget to oil stuff, things rust fast.
