I wanted to attach a little video of a real 100% stock W-30 I looked at and got running after sitting 12 years. This was the original W30 Vista Cruiser Wonder Wagon, one of three built by Hurst and owned by Joe Mondello. Sounded great after a long hibernation. If someone is interested enough, and wants to PM me, I will be glad to e-mail you the Quick Time movie I took of the car. Its 150 MB and I have no idea how to post it here directly.

I believe this is Comp Cams "Factory Muscle" version of the W30 cam.
Duration @ .050" is 233 in/ex.

First you must decide which is the real W-30 cam. And the source for that number. Comp uses the 402194 specs.

Mondello the noted Olds experts state their W-30 Factory Reproduction Cam as part number MW-30 Hydraulic Camshaft here:

As noted in post number 7

One source:

Two cams for the hi-perf 455's. One, #402194, is for the 390 HP, the other is #402569. This is for the W-30 unit

The 402194 specs are: (.050") 232*/232*x (Adv.) 308*/308* x .474"/.474" x 113* LS.

The 402569 specs are: (.050") 244*/244* x (Adv.) 328*/328* x .475"/.475" x 110* LS.
