well I appreciate u checking

Greg,
I am having trouble with my imgur photos. Usually I can post a photo but tonight all that I could do was copy the photo as a link. I do not know what is wrong.

Re: correct generator bracket for a 1959 & symbol ID

my question is....for NCRS purposes... my car has a 6/29/59 birthday ....im using a January 1 - June 31 date range for parts.
my block is 5/14/59 and the heads are matching numbers 1/21/59....is that ok?

Gregory,

Those dates are fine, the NCRS has a six month rule for judging. Head dates aren't judged anyway since you would have to pull the valve cover.

Thanks Joe, appreciate the input.

Speaking of valve covers, is there any real way to know if the covers are period correct or made later?
I have 2 sets both with the 086 part number stamped inside but how do I know they are from the late 50's? Or is there no way to know?

Re: correct generator bracket for a 1959 & symbol ID

I believe my photo below is of a generator brace for a 1962 Chevrolet V8 (283,327) w/A.C., GM # 3824073, as the dimensions of it agree with my 1963 Chevrolet Parts Catalog (Oct. 1962) which are as follows:
L = 13 3/16" (13.19")
Slot = 3 7/32" (3.22", slot width measures 0.42")
offset = 7/16"
The brace has the letter "B" stamped on it. I have alternator braces from mid to late 1960's Corvette with the letter "B". The "B" must signify the manufacturer.

It is similar to the Corvette braces (GM #3770360 and #3779210) as shown in the drawing below but obviously differs in total length ("L") and the slot length. The 3 Corvette braces listed in the drawing have different offsets.

Thanks Dave!

That will come in handy!

Greg,

You need staggered holes for a '59 with 3755550 heads, but late '59 changed to straight when the heads changed to 3767465. I don't know if over the counter had staggered holes and the casting flaw over the "o" in Corvette. You don't want the flawed covers which began around 1965 IIRC.

There are covers out there and you can always get them refinished by some of the specialty aluminum refinishers.

What heads do you have? The change occurred between cast dates May 5th and May 19th and are noted to be used up to June and July built cars according to the JG.

BTW, you don't want to use June 31(actually 30) for a car built June 29. Parts within the 6 month rule are typically at least a few weeks before the car build date. Maybe you meant to say May 31.

Hi Rich,

And here I thought I was having a great day.
Ok here are the heads.
The covers I have are staggered....what do I look for with "O"
The heads are matching.... dated 1/21/59 ????

Re: correct generator bracket for a 1959 & symbol ID

Greg, Those look fine. Machined surface Pyramid ends. Since no one sees the dates, no issue, and still in the 6 month rule to the engine date which was in May.

You don't want the flaw through the "o" valve covers like in this picture.....

Re: correct generator bracket for a 1959 & symbol ID

Thanks Rich....that's a load off.
i gave looking for the heads that were supposed be for the 290hp and had cooling holes drilled in them....nobody seems to have ever seen any.
So I understand...the six month rule applies to the engine parts and not to the car itself?.... so this engine once built...would be period correct for my car build date?

Re: correct generator bracket for a 1959 & symbol ID

Here are the valve covers I bought, I also have original GM boxes for them.

On a sep issue.....I have the 266 crankshaft....is that ok?

Greg, Sorry, I may have misled you. The 6 month rule is to the car build date, so technically those heads are 6 months and eight days before car build, therefore outside the 6 month rule, but head dates are not judged so not to worry. It's one of those situations where it's entirely possible due to Flint engine assembly non-FIFO inventory that it could happen though. Anything was possible then.

Those valve covers look fine.

I'm unsure about the crankshaft, someone else should know.

Re: correct generator bracket for a 1959 & symbol ID

Thanks Rich.....much appreciated.....but wouldn't 1/21 - 6/29 be 5 months 8 days?

Yes, my mistake. I forgot how to count months.
