I am looking at building a new engine for my 68 and the 383 seems to be what I am looking for. However I have never built an engine before, but now seems like a good time to start. I called and talked to a builder here in town and he gave me a cost of 2300 to do all machining and assemple the short block, if I provide the block. He sounded like he knew what he was talking about but I like to do things myself, is me building this engine myself a good idea? Is a 383 any more difficult than any other?
