64-L76 VAC question

[Michael S.]

Armed with Duke's parts numbers, and after searching through the archives I have been shopping for the correct can. I have come up empty, my local NAPAs no longer stock it So, I am wondering if the can sold by LIC is set up mechanically correct. I don not have an NCRS car so visual correctness or stampings are not important to me at this time. I just need to replace this beast with a good working can. Many thanks in advance for any suggestions.

Re: 64-L76 VAC question

Michael, I had one of the 'repro' 236 VACs, it cut at 11" instead of 8" vac, after a year it suddenly quit, diaphram took a dump! Stay away from them! There are some mechanically correct ones coming from an excellent source, don't know current status today but should be worth the wait. I think the repros come from the same source so be careful. NAPA etc. are all gone now, try to get from a reliable source and test it for proper function before using! These are really needed for proper runnung of the SHP cars!

Michael;

I recently went through the same excercise. I finally received a correct one from www.gmpartsdirect.com. It is labeled B28, and checks in perfectly at 0* @ 4" and 16* @ 8". It was $16.81 incl. shipping. I also bought a used BWD B28 from a fellow NCRS member, after a long wait for the one from the parts house, and it checks in perfectly too. Now I just learned that i will have a third one soon from volvette in Tennesse. It took them nearly a month to get it and it will be about $40. + shipping. I suspect it is a repro, but I insisted they test it first before shipping, which they did.

Stu, Save your money on the B28's as real deal 236 jobs coming very soon. Corvette Carlisle-L90's is where the dude in a dark green POC vendor trailer is supposed to be set up that will have some super dead nuts 235 VA's for sell quite reasonable or so I heard.
Yes the B28's are history and the remainding ones are being sold on the black market for mega buks. Lot of money to spend for an old Standard part that will get u dinged at a show. The new 236's will be tested and have nice warranty. Don't know the cost yet. John D.

Re: 64-L76 VAC question

All the B28 VACs are manufactured by Standard Motor Products. Although it appears to be out of production, you should check other brands to see if there is any remaining stock. There might also be a Wells brand (Autozone), but I don't have a p/n. I'm not sure about the Delco numbers. There was a thread on this subject in the last month or so. All of these "brands" have web sites, which should also provide information on retail outlets. They also have cross reference catalogs. The OE GM part number is 1116236.

Duke, We checked big time with Standard and yes it is true they have discontinued making the B28's.
They still have the B22's though which is about the same as the 201's. VC1802. Like you said anything out there on the B28's is remaining old stock.
Don't sweat it though guys as I promise you that you will be pleased with the new ones coming out. Thanks, John

Re: 64-L76 VAC question

John;

What you say is certainly correct and the way to go. Michael, however stated he didn't care about numbers or correctness for NCRS judging, only the performance characteristics, This is the same boat I am in because mine is a 63 340hp. The B28 I put in it will be in an attempt to improve it's drivability. My days for being judged are over, actually were when I hit the deer in 1992.

One other lead I ran into was at Advance Discount Auto Parts; All the name brands they used to have access to have been replaced by one from "Sorenson". They did not show any in stock, but it gives us another part # to look for. Check at your local store and have them look it up. I didn't even write it down as they were not able to get one anyway.

p.s. one of our members just sold a refurbished #236 on E-Bay for $49.00 a couple days ago.

Re: 64-L76 VAC question

Have ran across two vacuum advance units, one is a D1376 #114357 and a D1328 #115355. What do they go on?

Jim, Something isn't jiving. D1328 is 1116163. (not 115355). I have the box right in front of me.
I don't know what D1376 is though. John D.

Yes, the GM #1116163 was also known as Delco D-1328. Delco D-1376 is also known as GM #1115357. This vacuum control produces 20 crankshaft degrees of advance at 16-18" vacuum. The plunger starts to move at 7-9" vacuum. It's not a good choice for too many Corvette applications although it was originally used for some base engine applications.

The GM #1115355 was also known as Delco #D-1382

Re: 64-L76 VAC question

John G. I really messed up reading the numbers on these two unopened Delco boxes. The real numbers are D1382 #1115355 and D1376 #1115357.

AFAIK the 163 was never used as OE for any Corvette engine, but it was a common replacement number for many. It fails to meet the two-inch rule for any application.
