Goodbye Crane Flat Tappet. I hardly knew ye.
I'm just going to throw this out there, not to hijack this thread. I bought five or six cases of 20W50 Valvoline VR1 synthetic oil when O'reilly closed it out. I don't use it, but figured someone would. I paid $3.29 a quart and will sell it for that. I personally use Amsoil Zrod in 20W50 in my 408. Flat tappets should use high zinc at all times from what I have read.
