Power Valve Selection
72 Blu,
Here is ANOTHER news flash for you! By not using MVA during the magic years, Chrys got it wrong. The others got it right.....
Makes no difference what name is on the valve cover, these engines all work on the same principles. What does vary between brands is the actual timing #s, by a small amount.
Chrys, like the other companies, DID use MVA during the 70s decade to cool their engines. The engine was switched from PVA to MVA via an over-heat temp switch. This increased idle rpm, which increased w/pump AND fan speed to cool the engine. Why did the idle speed increase? Because MVA produced more hp & idle rpm increased as a result.
Another happy ending....
