I vote (and voted) for non-cloning, however, I'm an original, as GM built it, kind of guy.

Fundamentally, nothing at all wrong with cloning, as long as full disclosure is made at time of sale.  Build the car to suit your wants and desires.

After all, cloning is really only a problem when it is done with the up front intention to deceive, the legal folks refer to it as fraud.
842  Camaro Research Group Discussion / General Discussion / Re: sb flywheel (flexplate?) sizes on: March 14, 2006, 07:24:28 PM
I had a similar problem with a Tawain repro piece of junk that I bought for my 69 RS, 327 with powerglide.  It was a metal flywheel dustcover and I had to seriously work the metal to stretch it so that it would fit properly.  At first the holes did not line up with the bell housing at all and the starter opening was too narrow.

But then again, you get what you pay for and everytime you have to go to the repro market you are really taking a chance.  But that's an old and already well documented story.

Back to your question.  My understanding is that the flywheels for small block applications for 1st gen Camaros were two different diameters.  One has 168 teeth and one has 153 teeth.  I believe the 168 tooth flywheel is 14" diameter while the 153 tooth flywheel is 12-3/4" diameter.  Diameter of flywheel used on a particular engine was a function of Hp and compression ratio as opposed to cid, i.e. 327 or 350.  Higher HP/compression engines used the larger diameter flywheel with a higher torque starter.

Air cleaner that I have that I believe is a '68 is smaller in heighth than the one you have.  I believe it is for the base 210 Hp configuration which would have had a Rochester 2BBl with 1-1/4" throttle plates.

Sorry I wasn't able to help.

Will check tonight and get back to you tomorrow.

845  Camaro Research Group Discussion / Maintenance / Re: Battery draining issue on: March 13, 2006, 05:51:20 PM
One place I would start would be to check the dc amp flow with the battery charged and eveything turned off.  Use a multi meter and measure dc amp from the positive terminal to ground.  Although there is dc voltage from positive to negative, there shouldn't be any current draw unless something is "on", i.e. if nothing is drawing down the battery, current flow should be 0. 

If something is drawing the battery down, amount of dc amp might hlep isolate what it might be. 

If there is current flowing, you might also consider pulling the fuses in the fuse block one at a time and see if a particular fuse / circuit is the culprit.  If the problem is isolated in one electrical circuit, pulling the fuse for that circuit should stop the current flow.  Then you would at least have further information as to which circuit in the car's electrical system is problematic.  You would have to further isolate components within the circuit to find the exact location(s) of the problem.

By the way, any mechanic who:
  1.  charges you for a new alternator
  2.  charges you for a new battery
  3.  doesn't fix the problem
  4.  has the audacity to tell you he doesn't have time to work on your car

doesn't have a clue in the first place as to what is wrong or what he is doing.  He is simply guessing at your expense.  He is also looking for an excuse not to work on your car without coming out and telling you that he shouldn't work on your car because he doesn't have a clue.  Definitely find someone who has better skills and business ethics. 
846  Camaro Research Group Discussion / Restoration / Re: Rebuild or Replace Engine and Transmission on: March 13, 2006, 02:40:50 PM
I would also vote for keeping the original engine / transmission combination.  Depending on where you live, a complete engine rebuild (including balancing and blueprinting) is not any more than a new crate motor, in my area (Reno, NV) easily less.  Transmission rebuild (if needed) is entirely different.  Depending on what tranny you have, expertise to properly work on a 38 yr old tranny is often, in my experience, harder to come by than a competent engine rebuilder.

In any event, good luck and enjoy your ride!
847  Camaro Research Group Discussion / Originality / Re: Harmonic Balancer on: March 13, 2006, 02:30:41 PM

I've got the same engine.  Attached pic shows the balancer.  As you can see, (if you look closely) the timing tab on the front cover extends out at least 1/2 the width to maybe as much as 2/3 the width of the balancer.  I didn't take a pic of the balance by itself prior to reinstalling.  I'll be glad to measure width and diameter if that would be helpful.

This balancer is original to the engine.

As a side note, I have seen earlier '60's vintage 327 balancers that are about 1/2 as wide as this one.  Those would not be the correct for this application.

In the course of trying to find the correct air cleaner for my '69RS base coupe, I collected a couple of others, one may be a '68.  I have at least 3 dfferent variants hanging on the wall in the garage.  If you can e-mail me with the details, I'll compare to what I have and can send you pics as well.

Let me know.

849  Camaro Research Group Discussion / Decoding/Numbers / Re: EARLY 69 NORWOOD ALTERNATE VIN on: March 10, 2006, 07:40:38 PM
The engine that I put in my car (VIN#;124379N581767) was originally in a base 69 coupe, VIN# 124379N551248.

Both the partial VIN as well as the engine build date/code were stamped on the pad on the block in front of the RH cylinder head.  The particulars on this engine are:               

CASTING DATE:   J 31 8 (OCTOBER 31, 1968)
ENGINE CODE:   V1122FJ (Flint Engine, Nov 22 assy date, 327 cid/210 Hp w/3 spd manual

This engine was clearly manufactured after the one in the pics.  I can send a photo of the pad if that would be helpful.

Nothing was/is stamped in the area of the oil filter that I could see - wouldn't have expected to see anything since the engine code was stamped on the block pad.  Looks like there was some definite inconsistencies in the way Norwood stamped these blocks. 

Any possibility of the day and night shifts stamping the partial VIN's in different locations?  Have we seen the same thing for 350 engines as well?
850  Camaro Research Group Discussion / General Discussion / Re: RS Headlamp Cover Vacuum Line Layout on: March 07, 2006, 08:09:42 PM
This is a pretty good document that I found "on line" that has the vacuum line routing for '69.  I do not remember the source, wish I did so I could give proper credit.  Seems like I found the article by simply doing a Google search on the subject.

Hopes this helps

851  Camaro Research Group Discussion / Decoding/Numbers / Re: LT1 Question and For Sale on: March 06, 2006, 08:46:51 PM
I have this same block in my 69 RS Base Coupe; 327 cid/210 hp engine.

The engine in my car is definitely a 2 bolt main.  From the references that I have, this block was also used for 302 DZ engines, but in a 4-bolt main configuration.  Attached is the info. off of my block:

CASTING DATE:   J 31 8 (OCTOBER 31, 1968)
         1122 = ASSEMBLY DATE, E.G. 11/22/68
         FJ = CAMARO, 327 CID, 3 SPD MANUAL

I pulled this engine out of a 3 speed manual coupe, VIN # 124379N551248 back in March 1994.  The car was being parted out.  I installed the engine in my car last summer.
852  Camaro Research Group Discussion / Originality / Re: Question of build date vs. rear assembly date on: March 01, 2006, 10:05:20 PM
Although not a Camaro, my other car, a '66 Chevelle, has always been in the family.  It was my grandparents ride, and they purchased it on 30 March 1966.  The car was assembled at the Flint, MI plant in mid March 1966.  I have all the documentation on this car including POP.  The rear axle in this car was manufactured at the Buffalo Gear and Axle plant on 27 Oct 1965 (see code below).  I have also verified the numbers as stamped on the ring gear.  They are:  GM  3790628   1137  65.  The first series is the part number.  1137 is the number of teeth on the pinion (11) and the number of teeth on the ring gear (37).  This equates to a 3.36 ratio, which agrees with the CB axle code.  65 is year of manufacture.

The engine, transmission, and axle codes (and build dates) are as follows:

Engine Block:  F0318DE
Transmission:  C0322D
Differential:  CB1027B

As we all know, there are exceptions to every rule.  My Chevelle definitely has an October 1965 built rear end in a March 1966 built car.  Why the axle lay around from Oct to March (5 months) much in the same manner as nuch_ss396 axle lay around for 4 months before being used is a mystery.  And it would be very helpful to understand why that occurred.  But it is clearly an exception to the rule.  I would not be surprised to have someone state that the rear end in my Chevelle is not original (forget about the documentation) because it doesn't fit the "norm" with regard to its build vs the car's build.  We don't have all of the answers.

This one had some good info on Rochester Carbs, especially 2G variants which are important to my little ride.

The home page for the above link leads you in other directions regarding various manuals.

...and last, but not least, click on your favorite year (the home page takes you to other models than Chevy)
855  Camaro Research Group Discussion / General Discussion / Re: powerglide shifting on: February 23, 2006, 04:31:55 PM
The following link takes you to an "on-line" 1971 Chevrolet Transmission manual.  Powerglide is discussed in the first 23 pages.  It is a very good reference.

Quoting from pages 2, 13, and 14:

The transmission will automatically upshift to the high range or direct drive at between 10 and 68 mph depending on the particular vehicle and on throttle position.  When this shift occurs, the low band is released and the high clutch is applied which locks the planetary system causing it to  rotate as a unit

NOTE: The shift point speeds, shown for reference in this discussion, pertain to the Chevrolet 327 cubic inch V8 engine[/color]. Refer the chart for complete shift point listings.

Coast Downshift   As the vehicle slows down, governor pressure (holding the low-drive shift valve to the right) is reduced. At approximately 18 to 14 m.p.h[/color[/b]]., governor pressure is less than the opposing spring force of the shift valve springs

"Through-Detent" Forced Downshift   At all road speeds below approximately 70 to 62 m.p.h. the transmission can be automatically shifted to low range by depressing the accelerator linkage "throughdetent". This causes the production of maximum TV pressure and moves the detent valve to open TV   pressure to the detent passage. The resulting full TV pressure over-comes governor pressure acting on the shift valve. This action shifts the transmission to low gear as previously described. The transmission will remain in low gear until either the accelerator is released, or the car speed reaches the maximum upshift point (68-74 mph). At road speeds above approximately 63 m.p.h., governor pressure acting on the shift valve is high enough to prevent TV pressure from moving the shift valve. Therefore, regardless of accelerator position, the transmission will remain in high gear at all road speeds above approximately 70 m.p.h.
