Topic: 65 GT350 Block Marking

[slipkid]

The engine builder who recently built a new powerplant for my GT has 1965 60,000 mile GT350 engine in for rebuild.  First time it has been taken apart as evidenced by the cylinder head gasket date codes.  There is a spash of orange spray paint on the block - pic attached.  I am no guru on this by any means. Only thing I can think of is that the Shelby or perhaps K code blocks were indeed selected.

Thanks for sharing.  It is a hi-po thing, not Shelby.  Various parts have been found with orange splotches or spray.  Have seen it on cylinder heads and water pumps too.

Thanks for sharing - agree with Charles seen this plenty of times on K code blocks.

Is it known why the marks were applied?

Pretty much all hipo parts were marked with orange paint to help them identify quicker while assembling motors.

I agree, likely a quick identification mark - we just don't know if it was for the block, completed short block or completed long block (though that one would have had the sticker for that purpose

I think it was for all pieces I have seen it on the rods, flywheel, I think even a crank with an orange daub of paint on it once.

+1, believe it was identification of hi-po parts.

+2. Orange seems to have been the color to identify 289 HiPo parts. Besides the parts already mentioned, I have a low mileage 66 dated dual point FoMoCo distributor with orange paint still on the cam drive gear.

Few pics of a restored '65 K motor I did.  The orange marks were replicated as were found.  Obviously this is before the engine paint was applied:
