1231  Camaro Research Group Discussion / Restoration / Re: 'EY' coil springs.. update on: March 12, 2013, 09:43:20 AM
I have the suspension back together; had to sit the engine/trans in place to compress the springs sufficently to hook up the ball joints.   Just for kicks (and an early indication of where these springs are going to sit), I took it off the jack stands and put it on the tires yesterday.   As you can see from the photo, there are still a LOT of things not installed, so hopefully the front will settle down another inch or so.   I measured the height of the bottom of rocker at the front and at the rear and got 10-3/8" and 9-3/8" respectively. The designed in load rate for the springs are 370 lbs/in.    I probably need for the missing parts on the front to total 450-500 lbs to get the height where I want it.   The rear should also go down a bit with gas in the tank and spare/jack/etc in the trunk.   The car is an RS with cowl hood and dhrome/steel bumper.   the Photo shows all the stuff that's missing still off the front end.   If anyone has a feel for how much it all weighs, I'd love to hear it.  Smiley
1232  Camaro Research Group Discussion / Restoration / Re: A question for the paint system experts on: March 11, 2013, 09:14:32 PM
From 1957 thru the late 70's (at least) Chevrolet painted their cars acrylic lacquer.  Prior to '57, they used an even softer nitrocellulose lacquer.   No clear coats were used over this paint in the factory, but all the cars received buffing after painit.   You can still purchase acrylic lacquers in some places I believe although it's said that the formulations are different than in '69?   If your car were not metallic, you could use a single stage urethane, and sand/buff it, and achieve a finish similar to lacquer, but it would be a much better paint job.   It's said that metallic colors are more difficult to achieve an even metallic finish using single stage?

OK..  I checked again.   The 69 Camaro transverse muffler I bought from the dealership in '76 for my Z28 has a 'W' on it.   The Resonators also bought around the same time, have an 'A' on them.  See photo attached (since these parts are off the car currently).
1234  Camaro Research Group Discussion / General Discussion / Re: Thank you 69Z28-RS on: March 11, 2013, 04:40:07 PM
Yes, that is a very nice '68!  Smiley   ..  take lots of pix and share.. Smiley

PS.  The Thanks should go to CRG..  Smiley     I only passed along the Light Image Resizer info that JohnZ posted earlier and that I took advantage of.  I liked it and I'm glad you do too.  Passing along tips and info is part of what of what CRG  is all about. Smiley
1235  Camaro Research Group Discussion / Restoration / Re: Original Muncie bolts - head markings info on: March 11, 2013, 09:35:26 AM
seems pretty unusual to me to have *incorrect* side cover bolts...?  Are you sure they are incorrect?  Did you piece the trans together from parts?
1236  Camaro Research Group Discussion / Originality / Re: original transverse muffler date codes? on: March 10, 2013, 03:39:27 PM
I can't say about the factory installed muffler, but the one I bought over the counter at the local Chevy dealer in 1976 has a 'W' on the side.

Mine isn't bolted on, so it must be what you're calling the 'push in' type?

1238  Camaro Research Group Discussion / Maintenance / Re: 302 valve setting with roller rockers on: March 09, 2013, 09:28:39 AM
Original was 1.5...        1.6 rockers happened in the aftermarket much much later...

Lynn,

I mic'ed them at 0.595 .. that was after bead blasting, so  I figured they lost 0.005 to 'rust' over the years.  *L*
My car is an RS with ZL-2 hood vinyl top.. custom interior.. rem mirror...   trying to recall the heavy options...  RS was the biggie I think?   my total went about 65-90 lbs over if I recall...
1241  Camaro Research Group Discussion / Maintenance / Re: Front Brake pads - 69 Z on: March 08, 2013, 12:52:21 PM
Thanks..  I might do that..  OR modify the new pads to look like the old... 
1242  Camaro Research Group Discussion / Restoration / Re: undercoating on: March 08, 2013, 12:49:39 PM
JohnZ provided a great tip on an easy to use 'image reducer' recently.   I've been using it and it's very easy.   Go to
http://download.cnet.com/Light-Image-Resizer/3000-12511_4-10529104.html
and download it..  It's free.. and works great on single images or as many as you select at one time.
1243  Camaro Research Group Discussion / Originality / Re: original transverse muffler date codes? on: March 08, 2013, 12:47:42 PM
pics are pretty easy to do here, but  you have to realize no single image can be larger than 150 kb, and the totaly cannot be more than like 400 kb?   4 image limit I think but they would have to avg less than100 kb to do 4... 
1244  Camaro Research Group Discussion / Originality / Re: 1969, which pinion snubber on: March 08, 2013, 11:10:25 AM
You might want to include 'build date' in that data, Lynn..  in case it changed during the year?
1245  Camaro Research Group Discussion / Originality / Re: Exhaust System Configuration on 69Z'z on: March 07, 2013, 01:30:29 PM
Apparently that was the configuration at the latter part of the '69 model year, and is the configuration my car is supposed to be in, although I've never had the resonators on it.   Do you have an audio file of how it sounds?  Smiley    do you run headers or stock manifolds?  I'd love to hear how it sounds, as I have recently acquired good original resonators for my car.   I'm concerned they will make it *too quiet*.. Smiley
