You'll note - impressive care of this historically important vehicle, in the addition of rare NOS door reveal line protectors - extending partway up on the fender. A brave attempt to keep parking lot door dings to a minimum.

Seems to have worked - doors look straight enough to paint as is -

So is the Flow-Through rocker panel treatment.

Makes you wonder how many more of these derelicts are still in back yards across the continent - and beyond.

The following is an even better answer from the Archives:

In 1969, the clutched fan changed to a seven-blade design (still 18 inches in diameter) with aluminum fan blades. Cars with AC or K02 received the same fans as the 1969 Z28 and L78/COPO cars. There were two manufacturers of this fan and a mid-year fan pitch change (2 to 2.25"), yielding four variants of this fan.


•The 3937779 fan had a 2" pitch and was made by Schwitzer. It was used early in the 69 production year (until approximately November of 68) and has the part number and month / year stamped on the fan blades.
•The 3947772 fan replaced the 779 fan and had a 2.25" pitch. It was produced by Schwitzer and was used during the remainder of the production year (and through the early 70's) and has the part number and month / year stamped on the fan blades.
•There were two versions of an 'unstamped' fan made by Hayes-Albion. 3947838 was the earlier 2" pitch version and 3956684 was the later 2.25" pitch version. The fans are normally stamped H and FRONT, but no part numbers or dates are stamped on the fans. They are similar to the 772 and 779 fans but with minor design differences (specifically: the design of the center section and details of fan blade rivet attachment).
From what has been observed on original cars, the 3947772 fan and the unstamped fan were used interchangeably and with approximately equal usage. As noted above, the 3937779 fan was only used on early 69 cars.

I guess my unstamped fan for the BB is likely O.K. - now I've got to go dig it out and determine if it's a Hayes or a Switzer, and the pitch.

My 01C X77 original is unstamped, while my 03D Z11 original is a 772. I thought I read a long time back that the BB cars usually came with a 772, but I'll have to go read up on that from Jerry's Definitive book before casting that statement in stone (I have an unstamped fan for my 12A L78).

65  Camaro Research Group Discussion / Decoding/Numbers / Re: what heads part numbers for 67 350 on: October 07, 2014, 09:46:33 PM
Colvin states in CBTN that the 3890462 head was used from January 1966 through May 1967 . The 3917291 head was released in March or April 1967 with some minor use overlap (the dates aren't clearly defined). The 291 heads from March or April will have the sending unit boss present, but drilling and tapping for the sending unit did not start until May or June 1967. All 1968 applications using the 291 heads (350 and 302 w/ 2.02/1.60"s) had the sending unit location finished for the sending unit.

Close as I can research - I have two sets of 291's, both are late '67 and both are drilled/tapped.

Steve

Anyone know what the pin welding tool is actually called? Having trouble finding it.

Look in Eastwood's catalog. You can get a cheaper stud welder through Northern or Harbor Freight, but Eastwood has the pins and the collet. The moulding studs need to welded, don't use screws.

Below are photos of the ebay alternator (extracted from the ebay photo), and my original alternator stamps...  same PN and same date.   It looks OK to me ?



Gary,

Identical font - no doubt on this one -

DO use the bracket - otherwise it puts a lot of weight on the plastic dash bezel - might break it or the shaft recesses. Find a used one, or get a repro - a lot of them around.

You can use the 70-71 AM's, as long as the backlight screen/lettering is green and not blue. I think the power connector is a little different starting in '70, maybe later in '71/'72, but it's been awhile since I looked at 'em. Dimensionally they should be identical -

Steve

Posting a pic is pretty easy - set your camera or phone to a macro setting for good resolution on a close up shot, take the pic, transfer it to 'My Pictures' on your computer. When you copy it from the camera or phone, make sure you copy as a jpeg (or jpg) file. Download any software that you would like to resize with from the internet (I use Light Image Resizer. it's free), resize to 800X600 resolution, and then save it under whatever file name you wish. When you reply on the site, just browse at the add pics area, find your file, and open - it will add it to the post. You can then add additional pics (up to four total per reply, files cannot be larger than 200 kb per attachment, 4 total per post. You're done -

Hopefully this helps; somebody correct me if I've got the string wrong. When I switched from a Blackberry to an iPhone, I had to go through the learning curve again due to the enormous file size generated by the high resolution iPhone camera. This works for me -

By all means post a pic. There are an awful lot of restamps out there - if you're unsure about authenticity, I'm sure you'll get a large number of responses if that's what you're needing -

Steve

Tim,

Sorry it took a while to respond - had to wait for the weekend.

Here's pics of mine - on the car when I bought it in '73, stored inside (sealed) since 1980, fuse panel as well. If someone has a different flasher edition, please post it.

Steve

72  Camaro Research Group Discussion / General Discussion / Re: My New '68 Camaro Z/28 Butternut Yellow on: September 14, 2014, 09:41:27 AM
Steve, I did NOT take it out yet. I guess I just continue the wire to the coil, but bypass that resistor? I wonder if the dist. is out 180?

There is a resistor wire built in to the harness - controls the voltage to the coil, adding another resistor reduces the voltage even further. As long as you're running a stock coil and stock wiring harness, take it out of the loop.

180 out will run similar to the symptoms you described, but usually backfires quite a bit. Valves wouldn't be adjusted incorrectly if it starts and runs that easily. Ignition is the most likely culprit, followed by fuel delivery. Check your float/fuel level in the carb ?

Regards,
Steve

Danny,

Did you take the non-stock ballast resistor out of the ignition circuit, or leave it in ? It could be restricting your voltage from the coil enough to run you out of the energy needed to keep it firing. Stock coil ? Probably don't need one with a stocker -

I ran one for years (ballast resistor), but only when I was running a Mallory Voltmaster coil, stock distributor, to keep from burning the points up too quickly.

Just my opinion -

Steve

Is your spare block from a Camaro, Steve??

[/quote]

Yessir. In fact, the car it came out of is listed in Jerry's Definitive '69 book. Both blocks are Norwood - I understand Van Nuys was a little erratic in their execution of the stamping locations. Norwood apparently was more consistent once they made the changeover.

Steve
75  Camaro Research Group Discussion / Decoding/Numbers / Re: Earliest vin by the oil filter. on: September 12, 2014, 08:06:58 PM
My 12A L78 original block is stamped on the pad; the 12B L78 spare block I own is stamped above the oil filter. In between those two build weeks, I would guess. Dunno if it would differ between small or big blocks - I severely doubt it.

By the way, the location of the cast date codes on these two "272" blocks differs as well - one is above the pan rail on the side of the block, one is above the bellhousing flange at the upper rear of the block. Just thought I'd throw that in -

Regards,
Steve
