New to the Board..Looking for LS6 Chevelle info

[Hemiragtop]

Hello all, first let me first start by saying, "do not stone me for my username", I collect Mopars but love all Muscle Cars. I want to learn more about the 70 Chevelle SS 454 LS 6 cars. I'm a novice when it comes to Chevy's in general and I want to know what I should look for when purchasing an original LS 6, Data Tag info ? Body #'s , Codes etc. I'm sure like Mopars there are a lot of fakes and incorrect cars running around , any help would be greatly appreciated.

Thanks in Advance
