I’ve been trying to buy a solid roller cam for months, everything’s out of stock or on a 6 month back order.
So I was thinking of buying a .590 Purple shaft from Mancini because they are in stock and on sale, but I’ve been hearing of Q/C issues with flat tappet lifters for a while and don’t want to destroy my $5,000+ big block…
So has anyone recently used a purple shaft and done a successful break in? I’m only hesitant because I don’t know if they are recent production or NOS from Mancini.
