General Discussion / Re: Where to find 69 Camaro taillight chrome trim?

« on: October 25, 2013, 02:32:47 PM »

Are those part of the style trim group?  I think the base tail lamp lenses do not have those 2 strips but I may be mistaken?

Mild Modifications / Re: New 69 Z28 302 rebuild, dizzy has rev limiter. What is the best RPM limitation?

« on: October 22, 2013, 07:55:21 PM »

I run a Crane CD Multispark box that is triggered by NAPA high RPM points firing a stock coil. The crane box is hidden where the center radio speaker would be.  I have the adjustable rev limiter set at 7200 RPM.  The valve train is pretty stout and with the box set to 7200 RPM max, the fun is there and the springs should last a long time. This setup does not run high voltage through the points so the contacts stay clean.  No need to precisely set dwell and no condenser is needed either.  You can easily crank down the RPM limit with a small screw driver for "Valet Mode" if needed. :~D

Maintenance / Re: Master Cylinder Secondary Piston

« on: October 20, 2013, 11:55:49 AM »

I do know that NOBODY sells the secondary piston for the 1-1/8" bore MC.  Not part of any kit, not available by itself either. I know I tried.  My MC was original and I wanted to keep it.  The solution was to buy a brand new cheapo master cylinder and take the guts out to put in my original re-sleeved core.  You may need to consider that route if you can't find one for your 1" bore setup.  It is surprizingly inexpensive that way.  Just throw the left over casting in the trash.

I would be looking for a bad ground.  Start with the tail lamp bulb socket grounds and see if that is the culprit.  Add an extra path and see if it helps.

You can change out the flasher pretty easily to check but the bad grounds are my first guess.

I have used cast iron donuts with success.  The part number escapes me but they are GM parts.

It also has the owner installed accessory "dual fuel gauges and no tach set-up".

Decoding/Numbers / Re: 1969 Z/28 firewall crayon marks, question?

« on: September 25, 2013, 07:41:19 PM »

I have found "RGRN" on the firewall on my 10A "Rally Green" car.  The Interior paint color abbreviation was also written in crayon on the rear bulkhead. On this car it was "LG7" for "Light Green" interior paint/color with "X77" trim level. The crayon marks on the fire wall told Fisher Body what color to paint on the outside of the body and the rear bulkhead crayon marks told Fisher what color to paint on the inside of the shell to match the interior trim color.

This rear bulkhead marking style was used on cars built before X-Codes were being embossed on the Trim Tag.

Decoding/Numbers / Re: Timing Cover date codes

« on: September 13, 2013, 04:27:37 PM »

There was more than 1 way to stamp a cover date.  I can't remember the exact details but I did have an email conversation with Jerry M. about it years ago.  I had a big balanceer SB cover with an odd date stamp.  He has seen some julian dates and some that just are clearly not Julian that he could not decode. My cover was not originally on my car so I never recorded the stamp, sorry.

General Discussion / Re: Pic of My new car from 1979

« on: August 17, 2013, 08:44:38 AM »

That is a great look.  It brings back memories.  I brought mine home about that same time back in '79. I wish I had pix of it from back then.  It was all shackled up with the big and little look as well.  No flames on mine but it did come with some sexy stick-on pin striping -LOL.  Those were the days.

I left the points in and added a remote Crane multispark CD box. The points electrical contact surface never wears out because they are only used for low voltage switching. No dwell to worry about either. As long as they open and close, the sparks happen. No special coil, condenser is gone. Looks factory and has an adjustable rev limiter. Good for reduced RPM "valet mode" if you ever have to have work done on the car by someone else and have to leave it with them.

Just another way to do it.

Agree.   I think you can find replacement accellerator pumps that are compatible with ethanol fuels but they do not come standard in the carb kits. Lars Grimsrud would know more about it. You might try emailing him?

Originality / Re: Non dripper valve cover questions.

« on: May 06, 2013, 09:07:16 PM »

FWIW - I have a set of NOS polished ones with the drippers that I had Jerry refinish for me.  They now look like the original '69 dull finish die cast covers but they DO have drippers for better rocker arm lubrication. GM redesigned them for a reason.

Originality / Re: 1969 muncie speedo capplug

« on: April 13, 2013, 07:11:21 PM »

I came across this and wanted to follow up. The caplug I have saved in the garage appears to be smaller (3/4") than the one you have (1") . It also has no markings on the other side. 




The AIM calls for a 1" hole to be made if you order the M20 option. Does anyone know if the "standard production" speedo hole is 1" or 3/4"? This caplug might be from a different part of the car?  It might be from the rear fender well but that is the only other place I could remember finding one.

Gary,
You want 10 PSI for each 1000 RPM was the old rule.  I would look for that and run your known good pump if it passes the test. JMO.
Pull the cover off if you want to check for any wear.  I doubt you will find much.
