General Discussion / Vintage Certification @ MCACN 2016
« Last post by paceme on July 22, 2016, 07:49:24 PM »
Vintage Certification™  is again proud and excited to be a part of the MCACN experience. This is a must attend event. Come Join Us and have your car Vintage Certified at MCACN Nov 19th & 20th in Chicago

Vintage Certification™ is a judging program whose sole purpose is to recognize, provide status, provenance, and promote un-restored (survivor) vehicles. We believe it is the only program that focuses on documenting and benchmarking these cars. Our core certification team consists of Brett Merryman, Chris White, Alex Sahely, Frank Badalson, Roger Gibson, Steve Shauger and other marque specialists based on make and model. Each core team member possesses over 30 years experience as restorers, collectors, historians and judges in the hobby. Typically we spend 3hrs examining in detail every segment of your car including the underbody on a lift. To learn more about Vintage Certification visit our website at www.vintagecertification.com or the MCACN show at www.mcacn.com. This is the perfect venue to have your vehicle certified. You will be among and exclusive group of enthusiast who participate in this exciting event.

We understand not every original car is 100% untouched, and we offer five levels of certification, based on the originality of the Vehicle.
Vintage Certifications™ five divisions:

Vintage Time Capsule - Vehicles that are 95+% unrestored in all reference areas
Vintage Legend - Vehicles that are 85+% unrestored in all reference areas combined.
Vintage Heritage - Vehicles that are 85+% unrestored in four reference areas.
Vintage Legacy - Vehicles that are 85+% unrestored in three reference areas
Vintage Reference - Vehicles that are 85+% unrestored in at least one reference area.

Reference Areas: Certification consists of two areas of consideration, Originality and Preservation. Reference areas are as follows:

• Engine Compartment Area
• Exterior Body
• Interior Body
• Underbody
• Trunk (except Corvette)

Vintage Certification Preliminary Roster:


We have a few certification openings, so please contact me ASAP to secure your spot.


I will update the complete list of participants shortly, but here’s preview.....

You may have that if timing isn't tweaked.

Mine was the same way, even with the stock 30-30 cam.  Plus living at 5,000 ft where the engine doesn't make quite as much vacuum compounds the problem.   The fix is to run more initial timing, limit the centrifugal, and run your vacuum advance to manifold vacuum source for a bit extra timing at idle, then adjust the carb accordingly.   Once setup properly the engine will produce 3-6 inches more vacuum.

For example on mine, up here at this elevation with stockish timing settings and the vacuum advance hooked to ported on the carb, my engine only made 5 inches.  Not enough for brakes.  One good stop was all it had.
   I ended up soldering the centrifugal advance slot to limit that to 16 degrees.  I set my initial timing at 20 degrees (together 36 total)   I then dialed in vacuum advance with a limiter screwed down to the rear arm on the breaker plate made out of a penny.  Old trick as they don't sell the limiter plates anymore that I can find.  Making one out of a penny takes 2 minutes.   I limit the vacuum advance to about 12 degrees this way and then run it directly to a manifold source to add 10-12 degrees to idle timing.   So technically the idle timing is about 30-32 degrees (initial plus vacuum together)   This added timing goes away however as soon as you step on the gas and vacuum drops, and you centrifugal takes over when under load.  At light throttle cruising with everything together you end up with 45-47ish timing give or take while cruising, which works perfectly, good drivability and better gas mileage.  Works fine at 11:1 with the 30-30 cam on pump gas.
   This is how I set up most distributors for customers that have large overlap camshafts, as it tends to smooth the idle a bit, makes carb tuning a bit easier, and helps the engine produce vacuum.  With a 140 cam in a little 302 it's going to need tweaks like this for best drivability.
  With these tricks my engine is now making about 12 inches of vacuum up here at 5,000 ft which is plenty for power brakes.  It stops just fine now.

Hope that helps.
Thanks! You offered these tips to me before I had my car back and was relating "how it used to be" back in the day. I will investigate and probably have more questions.

I didn't intend to hijack Bill's thread, but maybe since he and I have similar problems, we may need similar solutions!

A very well known high performance dealer. About a mile from my house, it is now an office bldg. my 67 RS/SS and Jerry MacNeish's 13,000 mile 67 Z/28 came from Village as well. As a kid, we drove past it to get to my grandmothers house. They always had something cool in the octagonal showroom.

Beautiful car for sure!  It's so nice to be able to see these rare unmolested cars after all the years that have passed.
I'm trying to study some of these option packages and learn the details of them.  Since this car is an X33, it has the Z21 style trim option (I think).
Are the door edge guards somehow part of that?, or a separate option?, or maybe just a dealer add-on?
Also from what I gather the Z21 should have the rear quarter louver accents and it looks like maybe this car doesn't have them?  The side view wasn't direct, so I may not be seeing them.

Help a newbie out! :)

See reply #2 on page 1 of this thread, which explains why the quarter panel louvers (and the Camaro nameplate on the fender) are missing; the quarter louvers are part of Z21, which is part of every X33 car. The door edge guards were part of the Appearance Guard Group, and could be ordered separately (as they were on this car) as RPO B93.

"D off a 01C and a 09A car"

Kurt, do you know if that 09A car is from September of 1968 or September of 1969?
