I shall have to agree with everyone, that's the most info I have gotten on early HEMIs' all around! I've bought books and have talked to some people and neither have much info. I am in agreement with you on the hot rod issue. I admit that I don't know much, but I do love hot rodding. The extended blocked 331 wasn't my first choice(392,354), but it came to me for $150.00. I don't have a lot to choose from so I snatched it up. Anyway the guy was going to scrap the car so I felt like I saved a little HEMI history.
