Factory Correct Vacuum Advance - 1968 Camaro
« on: May 07, 2024, 04:16:30 AM »
Hi Camaro Experts -

I have a 1968 standard base model cpe Camaro 327/210 HP SB manual 3 spd with no a/c.  I'm being judged in the Legends class and need the factory correct vacuum advance.  The original distributor on the car has the number 1111440 with a date code of 8D8 (April 8, 1968).  The car was manufactured on May 14, 1968 so it's correct.  The Legends judging manual for 1967-1968 Camaros does not have the 1111440 distributor number listed.  I believe the vacuum advance should be MS 201 15 but I'm not sure.  Many thanks in advance for the assistance.  gwp4

A lot going on for me but I can try to see what I have. I bet I have 3 dozen or more distributors from 1966 to 1971.

Prior CRG posting about distributors used on the 1968 Camaro:

http://www.camaros.org/forum/index.php?topic=4548.0

I haven't found any documentation on the vacuum advance used on the 1111440 distributor and perhaps the information is available if someone has a vintage Delco catalog.

According to my 73 Delco catalog, 1111440 distributor received D1382 Vacuum Control.

My 1968 delco book say's the gm number is 1115355 which should be MS 355 for 1111440 distributor.
