You're right. I was thinking 1968 when he actually has a 1967. He has the correct pivot as per the 1967 Service Manual. Sorry about that.

You have the wrong pivot! (Which is why you're having problems finding the right coil.)

That's a very rare 68 427/390 only pivot and I know several guys that would love to have it!! As a matter of fact, I just contacted a guy on the NCRS looking for one, so you might be getting an email. He has the one YOU need!

My picture above is what you SHOULD have, and here's a page from the Chassis Service Manual showing what you DO have (far right drawing).

I love the 55 convertible picture with everyone standing around gawking. Ah, the good ol' days when the new car lineup was kept under wraps and it was a HUGE deal to attend the unveiling! Search lights, candy, popcorn, sodas, balloons, dealer trinkets, etc... I have a lot of great memories of going with my mom and dad to see the new cars throughout the 60's. One of the small thrills you have as a kid. Too bad kids today don't get that same thrill.

Thanks for sharing Chick. Great pictures.

3 is Oldsmobile and the transmission came from a 1968 442 built at the Fremont, CA plant.

Jerry does wonders with broken aluminum. HERE'S a sample of his work. I would contact him and see what he can do.

As a matter of fact, everything in the universe contracts with cold and expands with heat. That's just physics.

Well, I was informed by Rich that my answer was right enough, but I was wrong about everything in the universe contracting when cold and expanding when hot!!! There are materials that shrink when heated (i.e. Carbon fiber in the axial direction being one of them), so now my universe it turned upside down!!!

But as for why the factory used two different styles of coil when one would work just as well for both types of carbs just by flipping it over? No clue, but there must have been a reason. The General didn't do things just to do them. If they could save 1 cent on each car by using one coil they would have.

I'm no mechanical engineer, but I do know that ALL bi-metal springs contract with cold and expand with heat. As a matter of fact, everything in the universe contracts with cold and expands with heat. That's just physics.

I believe the differences between the two types of springs (Rochester -vs- Holley) is the way their made (?)

Bi-metal coils consist of two strips of different metals, which expand (or contract) at different rates as they are heated (or cooled), welded together back to back. (That part I'm positive on!)

(Here's the part I'm not so sure of) The metal that expands faster is on one side of the strip for one type of coil and on the other side of the strip for the other type of coil (?) This would make one coil move down when heated and the other move up when heated and vice versa, but again, I'm not sure if this is actually correct.

I'll see if John or any of the other guys can add anything to this.

BTW, I've studied those drawings in Ed's post above and something's not right because both the Q'Jet and Holley springs are reversed in the hot position compared to the cold exactly as if they had been removed and flipped over like we did.

That's because I just used Photoshop to copy and edit the two drawings. It's not "true to life", just a representation showing the movement of the coils.

post a picture of your choke pivot and I can tell you if you have the right one or not.

It should look like (or similar to), the picture I've attached. Also, are you using a stock intake manifold or aftermarket?

Ed

While there are exceptions to the rule (yours is not one of them), Q-Jet chokes "pull down" when they're cold, and (factory) Holley chokes "push up" when they're cold (see below).

One of the few exception is the 68 Corvette 427/390, but your carb isn't that one.

Unless someone has changed the choke pivot on your carb (very possible), you should be using the choke that pulls down when it's cold and pushes up as the engine warms up.

RPO K30 was a factory option (or dealer installed accessory) for 1967 and 1968, but only available on V8 Powerglide cars. In 1969 it was only available as a dealer installed accessory.

Ah! That makes more sense.

 I have a 67RSSS that is said to be a factory bb delete.

If you mean by "bb", a big block, there's no such thing as "big block delete". The 396 was an option, like a radio or power steering. It wasn't "standard equipment" and you can't "delete" options.

You have a 396/325 with a Rochester Q-Jet and a Turbo 400. The engine was assembled at the Tonawanda, NY engine plant on February 28th, 1966 and installed in a 1966 full size car built at the Arlington, TX factory. The casting number should be 3855961 which was used in 1965 and 1966. (The 1967 casting number would be 3902406.)

And yes, it's not unusual to see 1966 VIN stamps with different fonts and/or sizes.
