Decoding/Numbers / Re: Looking for guidance on my 68 Camaro

Ed knows where I am going with this.  If the indicator is original to the car and it is the Turbo 400 type, that indicates the engine was a 396.  Just one thing to look at...

Andi is it a column shift manual 3 speed or an automatic? If an automatic, how many forward gears?

Yes, without the original engine, transmission and rear axle it will be tough to figure out what it had originally.

Also remember this, Chevrolet played around with the RPM that they used for horsepower and torque ratings. The numbers below are for 1969.

427/335 hp - the 335 hp was @ 4800 - Torque was   470 @ 3200 (10.25 compression)
427/390 hp - the 390 hp was @ 5200 - Torque was   460 @ 3600 (10.25 compression)
427/400 hp - the 400 hp was @ 5400 - Torque was   460 @ 3600 (10.25 compression)

427/425 hp - the 425 hp was @ 5600 - Torque was   460 @ 4000 (11.0 compression)
427/430 hp - the 430 hp was @ 5200 - Torque was    450 @ 4400 (12.0 compression and more timing)
427/435 hp - the 435 hp was @ 5800 - Torque was    460 @ 4000 (11.0 compression - 3x2 barrel carbs)

In other words, look for grease pencil markings after removing the rear seat. Look along the top edge of the metal structure, behind where the top of the upper seat would be.

OK, I see the pics but that doesn’t look like it’s in a barn. :)

123677 or 124677 VIN in the door jamb is for convertible.

123377 or 124377 VIN in the door jamb is for a coupe.

If not, check the partials for VIN swap. 

If you have one that starts with 126 I would like to see a pic.

I “THINK” there might have been three.

Very cool car.  That would be a great project.

Price is a bit high.

Bill, what is your goal?  Just better stopping?  Do you want your car to look like it was an originally retrofit car with 4 wheel disc?

If you just want to stop better there are at least these options.
1. Buy a current kit from one of many vendors that sell the rear disc conversions.
2. Buy a service or possibly original JL8 from a certain vendor (HBC) but be ready to spend A LOT of money on one.
3. Take a full size housing, have it narrowed, use the existing larger drum brakes and then have custom axles made.
4. Take an full size housing, have it narrowed (using the smaller Camaro type ends - or better yet Ford type ends so you can have bolt in axles) and then figure out your brakes.
5. Buy all of the JL8 conversion parts.

Good luck.

General Discussion / Re: 1968 Z28 Power Steering
« on: February 09, 2018, 08:24:46 PM »
There is no breakdown of how many Z28s had power steering. We know how many total cars received PS, and that is 115,280 for the 68 model year.

It would be nice to know how many cars received different combinations of options, but it most cases we don't know that. One exception is for some of the engine and transmission combinations.

SMS - (Would be nice if we had a name) - you would be cutting up a full size housing and there were hundreds of thousands of those from 65 to 70.  Not a huge loss.

And actually I am following this thread because I may be doing this in the future.  I have 3 or 4 big car 12 bolt rear ends and Corvette disc brakes.  So it is just a matter of time...

Currently my car does have 4 wheel disc brakes, but the rears were added in the 90s.

Of course the dual quad setup WAS available during 'the 68 model year for the Camaro Z28. 

Actually, no it was not.  It was available over the counter and could be put on ANY small block Chevy engine.

You may say "semantics" or "taken out of context", and you may be right.  But I am just tired of hearing about factory installed dual quads on Z28s.  It NEVER HAPPENED! Just like the three deuce setup never happened on Camaros.

Yes, magazine publishers have always been more concerned about selling magazines than making sure the facts are 100 percent accurate.  That is why it can be dangerous to use magazine articles to document things without corroboration.

Gary - I do agree that the article was probably on a test vehicle, possibly for JL8 but that did not actually become a production option until about Feb to May of 1969.  Don't quote me on that timeframe because I am going by memory on that. It is obviously a "mule" and probably was testing other things too.

I also agree that 4 wheel disc brakes (even over the counter stuff) were not widely known to the general public and also not known very well by a lot of regular dealerships.  Performance dealerships with guys that were into racing knew, but not regular dealers.

See attached clip from the article, which is not correct.
