LS cranking oil pressure to prime?
I am getting ready to fire the new Texas Speed LS3 in my 69 firebird. I primed the motor as best I could through a pressurized tank I made and plumbed into the front Driver's oil galley. I ran 7 quarts through the motor twice and was able to get oil to 1 push rod on the passenger's side. I replaced the valve cover and removed the primer. With the computer and fuel pump disconnected, with a charged battery, I was able to generate 40psi at the oil filter location with a mechanical gauge. It took some cranking to get the pressure built up. Does this sound normal/ok? I'm using Joe Gibbs BR oil (what Texas Speed sent with the motor).
