Originality / Rocker Arms SBC with "O" on the end

« on: April 30, 2008, 05:28:11 PM »

Small block rocker arms with the "O" on them... I have heard that these are better than the more common "V" type...   Why???  I have maybe 15 of these O arms and cannot see any difference..
Maybe it is my vision, eh???   Ted

General Discussion / 1.94 or 2.02 over the counter heads is there a???

« on: April 30, 2008, 11:23:52 AM »

I have a non-matching set of over the counter hump heads numbered #3861492 dated K30 1 and 3973370 dated D23 0... Did these automatically come with 1.94s or 2.02s???  Is there a quick way to tell just by looking at them without measuring? How much distance is between the intake valve and exhaust valve of a 1.94 head vs distance between 2.02 intake valve and the exh. valve??? Both heads are press-in studs and I don't see any "factory grind relieving" in the combustion chambers.. Accessory bolt holes are already there...
Thanks!!!

Good afternoon...  Went through my carb pics and I have a 7027203 data disc unit looks like H6 Db or D8 - hard to make it out... Anyways,  Mr. JohnZ is correct...   Sending a pic of my carb's linkage to you... T.

Any idea if this unit came from Camaro / Chevelle???   Looks like everything is there with original wiring harness and speakers...  Paid 5 bucks for it, but, I don't know what it is from, or, if it even works....   Thanks!!!!   T.

Hi John...  To cut to the chase, do any judges who in fact scrutinize Q-Jets, even bother to look at the carb base encircled 7 digit numbers...  Mebbe I am wasting my time trying to free up the throttle plates, and I should apply another carb base not peculiar to the original carb body...  It just ain't gonna be original, but, if there ain't nobody a checkin' .... so be it...  I don't want to deceive anyone, but if it doesn't matter.....   Sorry John to be such a pain in the annular occlusion by keepin' on with this subject... To me it is kinda important as there is soooo much conniving (sp) a goin' on these days, eh???    T.

Mr John Z has previously responded on another question called "Rochester Carb Application" put forth by Dab in March and replied that in essence,  he was a Holley person not having owned a Q-Jet ...  Maybe he could envoy this "How are Q-Jets judged" question to an appropriate person in NCRS who, in fact judges Q-Jets...  Who knows, maybe the baseplates are not looked at for any type of originality and just the vertical numbers, line and Julian date codes have to be on spec??? 
Again, if no one checks, why not apply a baseplate from a GMC truck and, as long as the carb body is correct in numbers/ line and Juliian date, let 'er rip!!!  Could you imagine the displeasure of a big name collector(s)  thinking he has everything spec on re. original carburetor and, unfortunately, it ain't dah case...   T.

Good morning!!!  The carburetorman Phil Cancilla answered my query right away and his response to the Judging Quadrajets was as follows:  "The numbers in that circle on the baseplate are casting numbers.  Some casting numbers were used for several years yet others only one year.   Pontiac, Olds Buick are all different.  These numbers will not match the numbers on the carburetor body.  I cannot tell you for certain  if judges look at these numbers, I will tell you that if they are being scrutinized. it is being done by NCRS."

I then asked Phil a question about a 29251 RJ 1149 Olds H/O carb that I have and we are still conversing on this carb as to in fact if it is a numbered unit for a '69 Hurst Olds as one of the top 69 H/O gurus has the exact same 5 numbered carb, and his  unit is Julian dated a bit B 4 mine...

I do not belong to NCRS and in which case I am requesting if we want to go a mite further on this issue that they be contacted by a current NCRS member... I don't know where else to enquire, but I kinda think it is good question, and possibly deserves further attention...  Imagine someone with lots of green into a car and thinking he has the total package only to find out that is not the case esp. in the above Q-Jet base casting numbers. 
I wonder if Holleys have a similar casting system as I have a 3878261 3310 E H service replacement unit dated O 3 5 but someone nailed my baseplate, so to speak... Would I be in error  if I just bought another 780 baseplate  from wherever and passed it off like that...   Metering blocks /  fuel bowls /  etc etc are original to the GM number for a Z16 '65 Chevelle only it is a replacement dated carb...

Again, hopefully, an NCRS member could help out in this "Judging Q-Jets" question.....

Thanks Phil Cancilla for your valuable insight!!!   Ted in Montreal

Just keeping you guys updated on my question, I just e-mailed "thecarburetorman" this morning..   With big money being thrown in-consequential and minute parts that no one will ever see, I thought it kinda interesting to ask and understand how Q-Jets are judged.
If nobody checks a baseplate numbers as to correctness for a certain car, maybe I am wasting my time trying to "un-seize"  (3) 1960's collector Q-Jet carbs and could just throw another baseplate not correct for the throttle body onto the units...   Again, I am not trying to deceive anyone or I would not ask this on a Public Forum...  T.

Thanks Nuch for getting back to me!!!  When you think of it, all the money people are shelling out to have correct parts (even minute ones) that HAVE to be numbered correctly, there must've been  a list of  carb bodies with the right raised encircled numbers near the "HIC" to go along with specific,  Camaro applications...  Guess if I was trying to fool someone into buying a carb, I could just apply the right vertically numbered - dated -manufacturing  line - body onto a bogus throttle plate..   Again thanks for the contact!!!!  Ted

Hi John Z!!!  On the rear of the main body casting, there is a circle with 7 raised  numbers that are not the same as the  7 digit part number that you are referring to above..  I just got up from the basement and wouldn't you believe it, the carbs I was after were on the bottom of my Rochester carbs but in a thickly designed box...

Here we go: 1 st carb 29202 DH dated 086 9 with raised numerics 7037931 in circle near where HAC screw holes are... Inverted air horn and encircled numbers 7307703
                  2 nd carb 29202 DH dated 098 9 with same as above 7037931 numerics.
Did not take the air horn from the 2nd carb but, it is possible it is the same ....

Looks like Rochester / GM had a certain number of carb bodies by the number 7037931
and even though these carbs are 12 days apart, they used the same 7037931 for both
units...  Did not check the rods / hangers / jets as they might have been changed in over 39 years at one time or another... 

Started a thread on the 6th in the De-coding/Numbers section of this board , but as of yet no responders...  Was there ever a list of carb bodies that was peculiar to Corvettes and not Camaros/Chevelles/ChevII but used the same 29202.
Do judges go so far as to check the encircled numbers or do they just look for the 7 or 5 numbers that are easy to read on the side of the carb...
Sorry to be so long-winded, but you dah man!!!  Ted

Just checked a couple of Q-jets from the 60's and there is a circle with (7)raised numbers in it on the rear of the throttle body close to where the H A C  would reside.  Numbers are not the same as the vertical 7 numerical identification stamping.  I took the top off the carb and turned it over and there is another one of these id circles with (7)raised numbers... 
I wonder if Camaro had a unique carb body to it and Corvette's had their own distinctive carb body easily identified with the different numbers within the "ID" circles.
I am not referring to the round metal data disc on the driver's side of the unit found on the 66 and 67 carbs.
How might a Corvette conaisseur spot a Vette carb in lieu of a Camaro/Chevelle unit???
