Good thread. I’ve been thinking about this for my hellcat swap. I swapped the pan and pick up but that’s all. Does everyone think priming is necessary for a crate engine? Does the factory prime the crates or even do it in new cars?
I think it depends on how long the engine has been sitting. Keep in mind it’s a long was from the pick up to the pump. You’re going to have an air pocket to deal with.
To be safe I’m going to pressure prime my new 6.4. I just haven’t figured out the details.
