The '69 Z28 used AC43 (non resistor) plugs originally, but I just tried to buy some at a NAPA store, and R43 was all they had.  And they didn't have solid core spark plug wires..  I'm trying to put my original 302 back 'as original' as I can get it...   so I need some help from people who recently went thru this on which spark plugs, wires, dist cap, etc...  to run..    which work well, and lose fewest points in original class judging...   Is running carbon core (resistor type) wire and resistor plugs an issue?   (I've ran solid core silicone wires for 40 yrs, so I'm not very current on what is best or available..   :)

Originality / Survey - DZ4053 Holley Carb (vented?)
« on: March 11, 2009, 07:28:51 PM »
Most available information says DZ4053 carbs were never 'vented', yet I've seen some on late '69 Z28's that were vented (and that appeared to be factory original).   

I'm interested in collecting information from any owners of '69 Z28's that have original carbs with the front bowl vents.   Anyone?

Restoration / Jack and lug wrench color... paint codes?
« on: March 11, 2009, 03:46:09 AM »
There were a few posts a year or so ago, re bumper jack and lug wrench color.  Consensus seems to be gray on the jack base, and mechanism, but has anyone identified a specific spray can color that is close to the original color, or were there variations depending on the mfg of the jack?

Re the lug wrench, I had two originals (one was gray and one was black)..  the blakc one may have been repainted.   Was a consensus reached on that?

General Discussion / Chevrolet Performance Manual, or 'green sheets'?
« on: February 20, 2009, 07:04:46 PM »
Is anyone familiar with the original Chevrolet Performance book?   Around 50 pages of mostly handwritten engineering information and engineering drawings and parts numbers to help late '60's/early 70's camaro and corvette racers?   It was on 'green paper', so some people refer to these as 'green sheets' I believe.  I consider it to be the genesis or forerunner of the 'later' Chevrolet 'Power Book'.... 
Are these manuals available from anywhere?  Is there any interest in having copies reproduced?

Does anyone know of a readily availalbe Air Cleaner which has the same airhorn as the Cowl Induction AC for a '69 Z28?

Decoding/Numbers / PoP and component codes found in Sept '70 Parts book..
« on: October 31, 2008, 05:13:45 AM »
In doing a little digging thru a Sept 1970 Parts book (covering 1964-1970 Chevrolet passenger cars), I found very complete rear axle, trans, and engine codes for all Chevrolets (except Corvette) from 64 thru 70, and also a complete description of the data contained on the PoP's for each of the relevant years.   Is this data available online anywhere?  I know the Camaro data is available on CRG, but the PoP data seemed more complete and descriptive than what I recall from the CRG..

Originality / 'late' '69 Z28 Valve Cover drippers
« on: October 27, 2008, 06:54:56 PM »
Is there any evidence to show that 'late' (Sept and later 1969) Z28 valve covers had drippers?   I've owned my car since 1976; it has not been restored.   There was no evidence even when I purchased it that any work had ever been done to it, yet it had 'drippers' in the valve covers.  I'm hypothesizing that perhaps beginning at the time of 'normal '70 production' that the valve covers were updated to the drippers.   Current CRG information seems to claim that all '69 Z28 VC's did NOT have drippers?
