1969 - Orphans / Re: 1969 Block V0925DZ 19N697427
« on: February 11, 2024, 02:52:54 PM »
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.

Restoration / Re: 9431541 screw for tailpipe hangers

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.. :)

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  8)  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...

  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..

One needs to understand that NEW Springs purchased today are NOT the same as new springs installed in '69...

It's much more likely that the stamping was modified than the casting no modified.

3956618       68-79       302/327/350       2 & 4-Bolt

If the stamping was modified it appears to me that this engine suffix was originally 'EH' .. but someone overstamped the B (or 3) over the E...  producing a BH which I don't have in my reference.

Of course the engine deck/pad has also been milled (or otherwise modified) so it doesn't show the original machine marks, so it could also be a complete RESTAMP, but I'm leaning towards an overstamp as above...

The EH suffix was used in '68 on 250hp/327 ci engines in Chevelles...as well as some earlier occurrences...
