I bought one from Andy at East coast mopar and from Eric Delorio from team hellcat ,going with a new block is definitely the way to go ,I never gave a vin number myself,I made 1100 to the wheel on my stock motor ( 18 year model block ) and even though it was running fine when we disassembled it , we later found a crack in the block , when they say these motor can handle 1500 Hp ,that may be true but how long can they handle that is in question because there’s too many variables ( a lot have engine failures with less hp on here and won’t mention it because of embarrassment or because they dont want the tuner to look bad ) , tuning being the most important in my opinion and how much your willing to spend on the internals .but don’t fool yourself thinking if you buy all the best parts it will hold up , there’s a reason they don’t guarantee any internal engine parts
