340s and valley trays

Thanks for the clarification. Like in the BB Mopar, an OEM valley tray is needed to keep the oil "IN" in the engine as a matter of design. Keeping oil off of the bottom of those intakes is an OEM design benefit.

It's always made me wonder......have you ever seen dyno results with and without a valley tray? I wonder if it's worth anything in terms of power. Either way, I still think they are a good idea.
