The Hi-Po big valve heads for the W30 have and 'F' cast into them.

The Julian casting date...looks like 335, so that would be the 335th day of 1969 on this particular W30.

1970 W30 Distributor coded for manual trans, number 1111977 dated,

1970 W30 Intakes are cast aluminum and the words "Oldsmobile W-455" are cast on to the intake. For 1971, the casting was changed to read "Olds-W-455." Some late 1970 cars are said to have, "Olds W-455" cast on the intake.

This intake may not be correct for an early 1970?

Turns out that the intake is correct for this W30.


&quot;Cars built after 3 Jan 70 should have the OLDS W-455 intake. We have never seen a December BUILT car have one. The earliest casting dates are in the mid December time frame. The Early OLDSMOBILE W-455 intakes are some of the hardest to locate. We have also seen date codes as early as 13 Aug 69 on the Oldsmobile intake. &quot;
