Well I am back and just now able to post these authentic photos of factory originals for you all to observe. I will be posting some photos of OEM distributors below. 

I will not disclose what I know on how to determine the fakes from the originals but if you study these you will at least have an idea of what you are looking at.
I hope it helps the good guys out without educating those that would fake them and pass them off as OEM. 

I truly feel bad for the guy who gets one of the fakes and is caught up in the middle thinking it is an OEM. 
If I have crossed anyone in this boat please accept my apologies as you are an innocent by stander and a victim of this as well.
_________________________________________________________________________________________________________

BTW you should know these terms and acronyms... which are sometimes incorrectly used... ( all in the name of $$$) sheezzz

OEM = Original Equipment Manufacture  - the part made by the factory and or factory supplier.

NOS = New Old Stock  (of OEM)  - means the left over extras the factory and factory suppliers made... not new reproduction stuff.

Restored = means an OEM part brought back to new condition without changing its original integrity.

Re-manufactured = can only mean that it was an original part made into something else and disclosed as such.

Reproduction = means a newly made part similar to the OEM and often not exact do to copy right laws or lost manufacturing techniques, etc..

Fake = is a part that is not an OEM part being passed as such. Usually due to mucho $$$$$ and greed.  These are the folks who hurt the hobby.

Hi everyone. I'm Away at the moment.   I will post some photos of some factory OEM 67
Distributors when i return... and you be the judge.   There was a real o,ne on ebay at the time these were
Being listed for about half the cost.

I will see if I can get you some of this info. off my 12B Car, but my car is not an RS so I am not sure this will even help?  I have a buddy within my state who I can check with.

Isn't the AIM pretty correct?

Here is a 1111170 dist for a 67... but it is not as claimed.  I truly feel bad for those who end up with these parts who are innocent of the fraud...

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&vxp=mtr&item=271171687314


I hate to bring the light but it seems these crooks are running ramped again on eBay... and eBay is guilty of promoting it.

for what it is worth and thats not much...

if you can't see it I will not educate the bad guys so try to learn as I have to spot these.  It truly sucks to be the buyer of a big dollar item and not even have the real deal.

been there.. but if i can stop it by sharing I will.


21  Camaro Research Group Discussion / General Discussion / Re: 68 z fuel pump gph on: March 13, 2013, 04:18:27 PM
you could run it with the pump pumping to a gallon gas can and time it.  just an idea... but you would need to be extremely careful... good luck.

ps or pump 5 gallons, timed and get an average

PPS but you should really use a true measuring can along with the stop watch. Like the ones they use for weights and measures certification. Smiley
22  Camaro Research Group Discussion / General Discussion / Re: 68 z fuel pump gph on: March 13, 2013, 03:10:22 PM
Hey Janobyte,

My thoughts are on the same wave length... I too think the 1968 Z28 302 fuel pump would be the same or close to the same rate as the 396 Hi-Perf rate (even with an 8.5 psi pressure) since they both run the same Holley carb (#3923289-DZ - [#4053] 800 cfm).  I too think the 15 GPH is way to low for either of these engines.  (the 15gph flow rate was based off the listed 1 pint in 30 sec. to 45 sec.)

I am thinking just like you, those High Performance Chevy engines stay hungry and you gotta feed em good.  Grin  LOL

I also think that the SS 396 did use a different fuel pump from that of the Z28 302... but that may be just the difference of SB to BB.


gpm  = gallons per minute
gph   = gallons per hour

The required fuel flow rate might likely be more of a factor and determination based on the engines (heads, intake, cubic inches and exhaust flows & capacities) fuel air consumption flow rates.  

You probably already know this stuff but for the others reading these posts a little education (ed-u-ma-kating as some call it) Huh ... might help understand this subject.  Roll Eyes  I have found this information below in many automotive books...

Formulas:

air capacity = (rpm x CID)/2    (divide by 2 for four strokes, ie. 1/2 the cid)

cfm theoretical = ((RPM x CID)/3456)

VE = (cfm actual / cfm theoretical ) x 100

bsfe = fuel (#/hr) / brake horsepower (BHP) therfore => fuel #/hr = bsfe x BHP

Knowing this then.... Fuel #/hr x 6.25 #/gal = gph the flow rate of the pump

WHERE:
# = pounds
Gasoline weight ~= 6.25# at 72 F
1728 = number of cubic inches in a cubic foot (12x12x12)
3456 = 1728 x 2
cfm = cubic feet per minute
CID = cubic inch displacement, for example 302 cubic inches
RPM = maximum RPM,
VE = volumetric efficiency.  VE is the relationship between theoretical air capacity and the actual air flow of the engine.
BSFC = (Brake Specific Fuel Consumption), i.e. the maximum fuel system pressure, and the pump's flow volume at that pressure.


As Chick (an expert 68 Z28 member) points out the F.A.S.T. drag racers should have some info on this.   Wink

I would also give Jerry MacNeish an email shout out. Jerry is a long time Drag racer (and I think he's quite good at it too) who runs a 67 Z28.  Here is his link. http://www.z28camaro.com/

Also another good contact would be Ken Lucas, who has been restoring Camaro's at ConCours levels for years.  Here is his link http://www.lucas-restorations.com/

I am sure there are more expert members here at CRG who can give you a better answer than I have.  JOE Smiley

Listed in the 68 Chassis man...the 68 Z28 is 5 to 6.5 psi, pressure and volume is 1 pint in 30 to 45 seconds ....the same as all small blocks. 

So figure 1 pint in 30 sec.  8 pints per 1 gallon...then  figure 8 pints at 30 sec each equals 4 minutes per gallon

FYI the 68 Big Block is 8.5 psi pressure

25  Camaro Research Group Discussion / General Discussion / Re: NCIB on: February 24, 2013, 04:43:35 PM
Do you think its possible that they might have an original backup copy of that original data somewhere even thought they did the purge?

Also I don't understand why they are so protective of this information, maybe I'm just not seeing it but I cant see how it would be bad if it was shared...

" BTW, as a teenager, I always wanted to look inside those Dial A Grade pumps to see how they blended all those grades... "

Hi Phill, 

I believe it was done the same as today, basically with a blending type valve. Turning the dial selected the preset blend ratio.  So a selected grade would be made up of so much high test (Super gas) and so much of the regular gasoline...  just roughly figuring I think it goes like this;  to get 89 octane the blender takes a preset ratio at about 40% 93 octane and then take about 60% regular 87 octane blending them together for the 89 octane.  (It might be more complicated than that but I think that is the approach.)  Joe   Undecided

PS  - in the photo just above the center filter I think is the metering blend valve... the blue thing to the left is a Wayne vacuum motor used for collecting the gasoline vapors from your cars tank as you pumped gas...
27  Camaro Research Group Discussion / General Discussion / Re: Sunoco 260 on: February 24, 2013, 03:31:02 PM
FYI  - Here is some more info on the gasoline octane; IMHO  Wink

Octane is an 8-hydrocarbon chain and is more compressible without spontaneous detonation.  Heptane is a 7-hydrocarbon chain. It is very volatile and it ignites spontaneously under very little compression.  So 87 grade gasoline is 87% octane & 13% heptane which ignites at a given compression level.  87 grade is known as Regular gasoline.

Basically what you need to know is that you will get the maximum power from running the lowest octane without detonation... so if you can run 87 octane run that.  The higher grade octanes are only to prevent spontaneous detonation (aka engine knock - very bad). 

As you probably know most Chevy Camaro's had average to high compression ratios (i.e. about 9:1 I think for the 327, the L78 11:1, the L72 12:1, L88 & ZL1 12.5:1). The 10:1 and higher ratios would not run without detonation under 93 octane gasoline and that might have been pushing it for the 427's.

The higher the compression ratio the more power the engine made. (the 11:1 and higher stuff was really Hi-Perf race-car levels.) If I remember right, GM required these engines to run on a minimum of 98 octane gasoline; aka Super gasoline, Premium gasoline, etc...

but she forgot the 8,000-gallon underground tank full of 260 to go with it.  Grin


John, I really got a chuckle out this...   Grin  thank you. 

and BTW... that is a sweet garage... Grin

 Grin Grin Grin

Does anyone remember

Sunoco 260 ? 

Was it 102, 104, 110 or 120 octane?    

Please don't look it up .. just put down what you remember...  BTW I believe that Sunoco did change the octane several times...
