442 W-30 Documentation

[Stefano]

W30s are near & dear to my heart.

I have found original broad cast cards (look like an IBM computer card) Behind the bucket seat panel or behind the springs under the rear seat. If the car is a W30 ,the option is listed.

The W30s have a specific carb#, distributor# and heads.Check casting dates to see when the parts were made in relation to the build date of the car.

Heads have external date codes.

There are rear axle ratios which a W30 cannot have, check the code.

Original Red fender wells have distinguishing clues.

Check W30 emblem holes on original sheet metal to see if drilled or punched.

The original numbers matching "factory Doc Watson blueprinted" 455 will not authenticate a W30 as it externally looks the same(casting number) as the std. 455.

All W30s had the W25 Induction hood but not nessarily the rear spoiler, but these options were available on all 442s 70-72.

Great info by Stefano! However, I must point out that any of these parts can be put onto any 442 to create a W-30, and you'd never know it was a fake unless you have the original paperwork or broadcast sheet. That's one of the most positive things about PHS documentation for Pontiacs, it comes from a 3rd party straight from the archives, and there's no way to fake a car. Of course, re-bodies and other extremes can always be done, but that's a different topic.

With a W-30, you either get the broadcast sheet, locate the original paperwork, or take your chances. The difference in value today between a 70 442 and a 70 W-30 is night and day. Documentation, documentation, documentation...

Also, most 70 W-30 hardtops did not come with a rear spoiler, but over the years many owners (and Cutlass/W-30 clone makers) added one. The rear spoiler was NOT available on the convertible body (442 or W-30). That's probably the single biggest boo-boo I see at car shows on ragtop 442 W-30 clones.

All in all, the W-30 cars are one of the coolest Musclecars ever made. They are really starting to get into the upper stratosphere of Musclecar collectability, and some are trading at prices that were previously reserved for Hemi and Yenko cars. Just what the doctor ordered...
