That's why I suggested not messing with it, White Post is another good one for fast turns. What exactly are we doing to Black Beauty Sam [img]<<GRAEMLIN_URL>>/3gears.gif[/img]

My &quot;Black Beauty&quot; (as opposed to yours) is gushing with spring fever, but recently she is also gushing green fluids from her water pump. Eric's magic on the 4346 has her humming nicely, but she doesn't get far while spewing her juices! Still considering having Eric go through the engine. No issues but peace of mind mostly. I am going to register her (for the 1st time for me). In rural AZ I drove around my neck of the woods with minimal traffic and unwanted attention [img]<<GRAEMLIN_URL>>/naughty.gif[/img], but here it is a bit busier on the roads - time to legitimize! I already have a nice set of '69 Ohio plates that I picked up. This summer is busy for me but hope to start the D2 transition......can't wait [img]<<GRAEMLIN_URL>>/laugh.gif[/img] !!!!

That's a great looking set of plates. No reason you can't display them at the Chevelle show in August [img]<<GRAEMLIN_URL>>/dunno.gif[/img] of course you will need to bring the whole car since the plates will be on Black Beauty by then. Always a good time there.

Love the Chevelle show (northern OH). I will try my best to get up there and hang with you all and the Chevelles too!!

Art Gould for sure. I have sent them 3, the last one I got back within a week!!

Re: '69 L78 Water Pump rebuild
 

My plot thickens. So, it looks like my pump was replaced at some point, so I will need to track down a correct one. Here are the numbers on my pump:

Date Code: J 22 9 (Oct 22 1969)
Cast #: 3969811

Just out of curiosity I was wondering about the codes on my pump. I now know my pump is for MY '70 BBCs but I was under the impression that &quot;-811s&quot; would have a two digit year code i.e. &quot;69&quot; vs &quot;9&quot;. Anyone know when the cut off was when the &quot;-811s&quot; started to use two digit year codes?

BTW: I believe I need a &quot;3931065&quot; with a date of March, April, or May '69 (up to 5/23 when my engine was put together) - I will check with Goulds, but if any have a lead, I would appreciate it. Thanks

Sam, based on my inventory the 3969811 changed from a single year digit to a two year digit between November 11 1969 and January 27 1970.
