Is there a break down on the motors and transmissions for a 1967 Grand Prix convertible? Steve

[gtoric]

Not for convertibles only.

Here are the engine/trans breakdown for 1967 Grand Prixs with 400 engine. This includes hardtops and convertibles.
XY (400 & A.I.R. & MT) = 29
XZ (400 & MT) = 536
XH (400 & AT) = 15,467
XJ (400 & A.C. & AT) = 24,563

428 numbers are included with all full-size Pontiacs, so there are not GP-only numbers available for the big-engine cars.

If you have a Convertible and need to know, file for your PHS with the vin number and it will tell you the good news.

The only way I know how to find that one out.

So Steve,

Did you pick up a new toy? What did you find? When I bought mine I toyed with the idea of trying to chase down a 428 4-speed car, but then decided my knees were bad enough and instead found the color combo I wanted in an automatic.

Post up some picks if you have them

There were 36 built. But there is no break down on the trans.

36 of what built?

[Stuart]

Yeah, 36 of what?

I've never seen any accurate breakdown numbers as far as how many full size Pontiacs got a particular engine combination. You can do some estimated guesses based on the engine production logs that come with the PY documents, but that's about it.

70BADBOY wanted to know how many 1967 GP verts had a 428. The of what question is a 1967 GP verts with 428 engine.

He said,

" 67 GP production numbers

Nothing in there about whether he was talking about a 400 or 428. More importantly, where did you get that figure from? I've never seen any indication anywhere that production breakout numbers are available for full size Pontiacs, unless someone at PHS decides to sit down and go through the microfiche car by car.

Well I have had this information for years. To be honest with you I cant remember how I aquired it. But I do know that it was from a good source.

[Stuart]

Just for 1967 GPs, or for other models or years?

Although 42 is the meaning of life, am I missing something regarding this reply?

Wasn't the original question "Is there a break down on the motors and transmissions for a 1967 Grand Prix convertible? "

We know that there were 40,595 engine assemblies produced for the 400 and M.T. combo.
We also know that there were 42,981 total G.P.s built in '67. That leaves us with 2,386 G.P.s w/428s.

According to the Standard Catalog of American Cars, there were 760 total syncromesh-equipped G.P.s built in '67. With 565 syncromesh-400s documented, that leaves us with 195 total 428 and M.T. G.P.s built in '67.

Judge Man tells us that there were 36 converts built with 428s and syncromeshes, in both the 360 and 376 hp versions. This gives us a figure of 159 hardtops with syncromesh and 428s.

It seems to me that Diego R. had some additional production breakdown figures. Maybe he can jump in here? Are you out there Diego?

[Stuart]

Also, don't forget that syncromesh number includes three speeds (both on the floor and on the column) as well as four speeds.

Chances are the majority of Grand Prixs with manual transmissions had four speeds, but probably not all - I used to own a '65 GP with bench seat and a column shift auto. It was also two tone, with a Mayfair Maize body and a Starlight Black painted roof (not vinyl) so there are some weird ducks out there.

Yep, I'm here!

[gtoric]

Some new information has been uncovered at the GM Heritage Center. Their records (compiled by Fred Simmons in 1989) reveal that 205 total '67 Grand Prix convertibles were assembled with synchromesh transmissions. Since we have previously concluded that 36 of those builds were 428s, that means that there were 169 400 c.i./4 and 3-speed-equipped GP convertibles built.

Those same records also indicate that 559 (out of a total of 1,457) 428 H.O.s were installed into 1967 Grand Prixs, both Sport Coupe and Convertible.

[Diego]

But where did that 36 number come from?

[aronhk_md]

Well, regardless, I guess my 400/3 spd is one of 205 made. Very interesting. Still think it would take someone at PHS a couple of hrs to sift through the convertibles to put this info together. Not ready to order the PHS yet, so I dont want to call and bug them. Someone who has already ordered PHS might be in a better position to call them and ask if they'd mind looking.

[Diego]

It's one of less than 205 made, you mean?
