68 std distributor 1111440 and vacuum advance can
« on: November 03, 2020, 04:19:21 PM »
Hi,
I'm getting my car running after sitting ~15 years.  The vacuum advance can is not working and I need a replacement.
I've read the previous threads, JohnZ's 101,  and advice (thanks to all, great info here!). I plan to get a "B28" and go to manifold port as recommended. I found an Airtex branded version PN  #4V1053 on Rockauto.
Two questions.
- I have the base 327/210hp with a 2bbl rochester.  It appears the vacuum for choke pull off at bottom back is manifold vacuum. Just checking that would work if I tee in there.

- I would like, for curiosity, get a vacuum can for the ported vac as it is now and get it running as it used to run and then switch. The current can is marked MS 355 15.  There are SMP VC171 "B22", VC24A "B1", VC169 "B9" cans listed in Rockauto as replacements for original.  Does anyone know the "correct" SMP can number or PN which corresponds to the "355" can?

Thanks for advice
Ed

Ed,

The original GM part number for your vacuum advance is 1115355. GM stamped the last three digits of the part number onto the part.

There are plenty on eBay for sale.

Thanks!
according to the SMP catalog the SMP VC24A "B1" is the replacement for 1115355.  Since I'm just doing this for interest, not originality I'll just get it to play around for now. I appreciate the info.
