Lifter preload...more or less?
No lash is true but how much preload?
I bought a howards retrofit hydraulic roller for my SBC, that card also said zero lash and tick tick tick tick.
Hydraulic solids are set at zero, at temp you get .006 squish.
Hellcat lifters are all solids.
Just by definition, they cannot be the same.
I just got another 2011 from Auction, supposed to be nothing wrong with it, but right. Anyway, that has the added problem of VVT, so its keeping one or getting back into a chevy.
