Default Re: 70 W31 Olds Ram Air Valu ???? BE EASY ON ME PL

Standard motor for the 70 442 was a 455, 4 barrel.

The "W" designation is just an add-on package to the 442 (W30) and Cutlass (W31).

You could get a 455 in a Cutlass in various configurations.

The W30 455 had select fit parts including a more agressive cam, special heads, and some other parts like the aluminum intake.

The W31 was the "350" version of the above.
