General Discussion / Re: July carb on a July 68z

« Last post by black69 on March 29, 2025, 05:50:24 PM »

Thanks William,
I am on the ‘probably not page too’. I know with so few Camaros made in July, I wondered they would have been burning through June carbs. I need to check again, thought they only made 2000 plus total Camaros in July, and with the ratio of z28s out of that number, it had to be not that many z28s that month. Nickey Chevrolet told the owner of my car that it looked potentially it won’t be made and if he wanted a 69. Something unknown was holding it up, maybe same thing held up others.

Probably not.

Early Norwood 1969 Z/28s built through the end of October 1968 had 864, 872, 875 carbs.

General Discussion / July carb on a July 68z

Hi, I have a 68z with a 7C body and an engine stamp build date of July 8. A friend wants my april first week carb for his in trade for a second week July DZ carb. Would this July carb be ok for mine?
I never had the original carb for my car so please don’t think the April one came originally with my car, always hoped it was in range though (barely). If the July one is better, that would be good and I could proceed with a trade.
Thanks, Bob

Hi!

I am trying to learn this and get the correct pump, so any further clarification would be helpful!   In some quick research, the 40568 you mentioned was only used on small block Corvettes.   And, I was under the impression that not all 396 used the same one.   The L78 396/375 one had a longer tongue lever and one website said if you used a different 396 carb the lever would break.

Sept of 1967 used a 40568 on all 396 engines. The 40470 was used in 1967 model year 396 375hp. In or about Aug 1968 the 40568 was used. The first 40727 I have recorded is Oct 1969....Joe

Hi All,

Can anyone tell me the correct fuel pump for my 1968 L78?   Build is Sept, manual transmission if that makes a difference.   I have seen 40470 and I have also seen 40727 listed.   Also the GM part number would be appreciated.

Thank you!

Post a picture of the axle stamp. How about a picture of the casting date stamp.

General Discussion / Re: MO Block

« Last post by GMAD_Van Nuys on March 28, 2025, 10:50:28 PM »

I have a 1987 parts catalog from MacPherson Chevrolet and a "smallblock V-8 bare block, high tin alloy casting, 4-inch bore, 4-bolt caps, 2.45 inch main journal cranks," had a list price of $631, but available for $536.35.  I'd imagine that a replacement MO block back in the 1970s was available from GM for a similar price and if someone damaged their original block, they would probably just replace it as matching numbers back then wasn't an issue.

William and David thank you both for a reply. I need to dig deeper on the rear axle code. Car has evidence of being raced in the day. So trans was probably replaced with no vin on it.
