67 Tank Sticker Question

[Michael M.]

Hi, Years ago I helped a friend with his 67 conv. We had to pull the tank and it had its tank sticker. He didn`t see much value in it but I got it off and stored it in a book. Only recently did I realize when I found it still in the book where it had been for the last 30 years. I called him and returned it as he stills has the same car. I noticed reading one of the options was to convert 390 HP to 400HP along the bottom of the sheet. It also listed among the first several options as a 390HP 427. Did they all read this way or was there an actual conversion of a 390HP to 400HP? It was a single four barrell when he bought it in the early seventys. It had a Q-Jet and intake someone replaced the 3X2`s with. I ask him to copy it for me and I will post if necessary. Thanks, Mike

Right Michael,
Yes and Yes.
400's were converted 390's.

I'd say he owes you big time for having the smarts to save it !!! I hope now he realizes the value of the little brown paper you found !! Nice job !!

I don't think that is correct.

I don't think that is correct.

The tripower setup was put on at the factory and not at the dealership.

Right. If they were dealer installed, we wouldn't have the beloved overspray on the intake !!

Re: 67 Tank Sticker Question

I've often wondered why they read this way. After all, the engine suffix for the two engines is different so it isn't like they started with a group of identical short or long blocks and configured them as 390 and 400s on the fly (even though they are otherwise identical).

Anyone know why this is?

Do L-89's read similarly?

Possibly the word conversion appeared to let line workers know of other items on the car that needed to deviate from the standard 390 configuration ??

Hi Tom,

That makes sense but wouldn't it have been just as easy to simply list it as L68 at the top where L34 appeared since they were 2 mutually exclusive options?

Possibly it was simpler for other parts of the line to not know or care if it was an L34 or an L68 car since to them it did not matter (chassis, body, interior, etc.).

Not trying to be argumentative, but rather trying to fit one more piece of the puzzle.

Re: 67 Tank Sticker Question

Good points Joel:

My answer was sure not based on fact, but just on speculation. Not sure if anybody actually knows the real answer.

There are many questions regarding how things were done that would sure be fun to know !!

Re: 67 Tank Sticker Question

There was no "conversion" performed anywhere, although it's listed that way on the tank sticker; the L68 was built originally with the 3x2 intake at Tonawanda, and was otherwise identical in all respects (except for the pad stamp suffix) to the L36.

We'll probably never know why Engineering chose to have the tank sticker show the "400hp conversion" wording for the L68 line item, but there was no actual physical "conversion" done at all.

JOHN is right. Engine is exactly the same as a 390 but had a tri-power. I guess it was worded that way so there was no mistake that it was a 435. I have a original owner 400/AIR Coupe. Original owner wanted a 435 with air but was told this was the next best. This was also printed on the window sticker.

Re: 67 Tank Sticker Question

FWIW, my 69 400 HP car is also listed as a 390, then in the options, it says "390 To 400 Equipment", along with the L68 code.

Every 67 to 69 400 tank sticker that I've seen is listed that way.
