L6 cylinder head data for a new report

[bcmiller]

The casting numbers might be in a book called

Chevrolet-Inline-Six-Cylinder-Power-Manual

If any of you have that and could look to see if there might be some casting numbers and usage in there, that would help. Otherwise I might have to buy a copy.

I can get a copy to look at, but I’m away till Thursday, If you can wait. It would be the red copy, not the blue.

[bcmiller]

No rush. And don’t buy it just for this purpose. It might not have any casting numbers in it.

Casting: 3927763.  I guess I don't know where to look for casting date on heads - kind of dirty from sitting for 35 years.  Car was 1969 model totaled in 1988 still have 230 engine.  VIN 123379N545064.  Engine pad does not have VIN # only the assembly date/eng code part is stamped.  Have protect-O-Plate, my aunt bought car new in 1969 and I was second /owner.  Car was Torque Drive 2-speed auto (Powerglide without the modulator) had to shift from 1-2 and 2-1 on column manually - engine coded 'F1112AN' and has yellow AN written on rear of block.  Block casting number 3921968, date K 11 68.

Jerry, thanks for posting those pics!

The head casting date and a partial casting number should be in the area between the valve springs and the side of the heads. See pic.

Also I think it would be cool in you could post a pic of the yellow AN writing.

[JerryGingras]

ok thanks, the casting date is probably near this "763" I took a pic of yesterday, I'll get back over to the building where it's stored in a week or so and look closer and get that.  Also here's pics of the 'AN' (appears upside down when engine in normal position).

[bcmiller]

Thanks. Yes it will look something like this.

[bcmiller]

Do you see 7763 cast on the outside of the head toward the rear between the spark plugs?

[JerryGingras]

Yes, I did happen to get a pic yesterday of the 7763 on outside of head - think it was on left side, then didn't see anything in the next spot (center) then on the right it had 41F 5060. here are pics left to right (obviously on the side of head w/o intake/exhaust):

[bcmiller]

Thanks for those additional pics.

On my block behind the dipstick,  it is an L code....Might as well get the info now instead of later.

[Her68His69]

Just got home. 16 hours of driving. Let me know what else you would like out of the red Santucci manual

[Her68His69]

Having trouble posting pics. Sorry if I post duplicates

[Her68His69]

Hope this is better

[bcmiller]

I will take a closer look but so far doesn’t say anything specifically about Camaro use, correct?
