New Timing Chain Set Loose?

I found an NOS Mopar performance double roller set for my most recent/6 build.... I think the package was dated like 1987 or something like that. But yes I e been done with cloyes for some years now. I do more SB stuff but with them I've had good service out of the Edelbrock true roller sets. I don't think they have them for a /6 unfortunately
