That is a fantastic read! I'm going to print that out and keep it.
I don't have anything that shows a lot about identifacation, and was worried I had already screwed up by ordering my parts. The info from you and ffr have made me a lot more confident about this whole mess. The only other engine I have been through this with is an old 302 and there isn't much you can mess up with parts wise on them. This being my first venture into big block territory has been a big learning experience to say the least. From what I have learned and been told, I might finally be on my way to 500+ normally aspirated horses. YEEHAW!
