My understanding is that the current chain has very few hours on it . So unless it was a junk chain to start with I see no issue in reusing it . If the logic is that chains are worn out by 3k then we should all be replacing them every 3k... the chain doesnt know it was removed and reinstalled .
I run a billet rollmaster in my 408 with a .648 solid roller cam and a double roller Cloyes in my milder 360 for the DD Barracuda . So its not like I don't appreciate good components but if this is just a run around car I dont think the OP needs to go Super Duty . Hell even the OEM plastic gears went 50k before needing replacement.
