The NCRS data comes from old punched cards...  When I first got mine, it had the wrong data on it.   I reported what I knew of my car's origin, and they rechecked the data.   When I got the results it was corrected and reported to me that the first error was due to damage on the punch card.

Re the banking (31 deg) at Daytona...

As a NCM member in 1999, we were invited to attend the inaugeral 24 hrs of Daytona race as a guest of 'Corvette and Chevrolet', and to follow the Pace car (a Corvette) during the pace lap in our Corvettes.   I was driving my 1990 ZR1 as we followed the Pace Car around the track (at about 25-30 mph).   Even though we were 'told' NOT to drive up onto the high bank, I couldn't resist... and I found at that low speed, the car really wanted to steer down the bank, so I had to steer pretty hard UP the bank just to maintain myself on the banking.   I didn't stay up there long, but wanted to take the opportunity to do it! 

Corvette Racing's first event at Daytona International Speedway was in 1999 at the Rolex 24 At Daytona, marking the beginning of the modern era of Corvette racing. The C5.R, which stands for "racing", debuted at the race and was a regular competitor in global GT racing for the next five years. The team ran a six-hour test at Daytona over four days to simulate the 24-hour race, and Doug Fehan led the car into the race. Although the C5.R led the GT2 class for most of the race, engine issues caused them to finish in third place. Despite this setback, GM executives were impressed with the car's performance.

Wondering how this thread took a turn into a 2nd gen Camaro photo thread?    but..  since it has, it gives me license to post photo of my '70 Z28 that I bought in the early 80's.. and sold it later in the 80s during one of the gas crunches!

Block appears to have been cast on 1229  (Dec 2, 69)... ?
VIN is a very late one and corresponds to the early december timeframe?
But how can the engine assembly be BUILT in September??

What did I miss here??   Anyone?

If your car is a '69 Pace Car, then it doesn't use 'door cards' in the strictest sense of the term.  Instead the door panels are custom panels with custom (not flat) support underneath.

David,  the screw you are referencing (1/4-20 x 5/8)  describes the screw (2 on each side) that hold the hangar bracket to the frame.  They are also 'self threading' screws from the factory.

I thought the screw that Doc was inquiring about was the longer screw holding the pipe clamp bracket together around the pipe...  My photo posted previously shows both of these screws removed from the hangar part.

Doc,

I think I received a PM from you (but I'm unsure) asking about that?   I tried to reply but I think it didn't work..  so I'm attaching a photo of my disassembled tailpipe hangar (with the screws) so maybe you can estimate the length..  My estimate would be ~ 1-1/2"  in length. \

There are shops/individuals who can take an original radio and convert it to have FM and bluetooth etc.   if you don't have an original, I'm sure someone on Ebay will sell you one..

Here ya go - whatta deal!

Those wheels could very likely be from an early 1970 Monte Carlo as their rallye wheels were also 'YH' code.   THere probably were lots more '70 MC being built at that time than '69 Z28s...

Monte Carlo wheels have smaller different shaped vent holes. Monte wheels are mostly dated K-1-0....Joe

Joe?  Are you suggesting that all 'YH' coded wheels are NOT the same?   Your example (K-1-0.._)  would be wheels produced during the 1970 calendar year, but as I recall Monte production began on the normal yearly schedule at that time (beginning around Sept of the prior year)...   Do you have a YH example produced during 1970 (per your example K-1-0_) that has smaller shaped vent holes?

1967 SS/RS family    any idea on the tags ?

Maybe Washington, D.C. or military. 

Yeah that bumper sticker reminds me of old military base permits

That's probably exactly what it is..      One was supposed to remove those decals when cars were traded or sold, but many/most didn't do so..  This one on my car was put on in 1976 or so...

GM made the best ones, and if you are careful and patient good GM examples are still available..  Check out y our local swap meets..

WaltZ:  If your wobblers have good metal and no physical damage from an accident, then I suspect they can be straightened.  There is a local company here (Wheel Fixit) that can do it and there are probably companies local to you as well...

"Realize this is an old thread.  Only 1 of 2 threads that a search for "Mallory RevPol" found.

  The Mallory RevPol DoubleLife dual-point distributor is unique?  It only has a 4-Lobe Point Cam.  Each point set fires only 4-times per revolution rather than 8-times, each point-set fires only 4-times each to fire all 8 cylinders.  Is this correct?
...
  The Mallory RevPol DoubleLife Dual Point 4-Lobe Distributor should be more rpm friendly since the point-sets are cycling at a lower rate?"
--------------------------------------

YES, to the above two points about the Mallory RevPol distributor..  and as I stated previously...

I can only speak for my own... When I bought my car and rebuilt the engine in 1976, the 480' was sloppy, needed shimming at the very least, and I had a perfect Mallory Rev Pol in hand, so I installed the revpol and used a Judson electronic magneto for the coil- that worked great, would rev to 8G+ without a miss...  I would not hesitate to use it again in a modified Z28 or other small block Chevy car...

DavidK posted..  "Accessories/options effect the overall stance measurements."

As they do the *springs* utilized by the factory..  based on weight over front and rear ends of the car..

Ed,  Do you have a reference for the Commercial, AGri, etc.. stampings??
