67 gt 500 waterpump

[clint67]

My waterpump has c8ae-8606-d with date code 7c6

Is this odd or normal and is it correct for 67 Shelby gt 500

What is the build date of the car and/or what are the casting dates on the block and the heads?

[clint67]

If I recall correctly the block and heads are feb 67 and the car was completely in April 28th 67

The pump date should be close to the block and heads. It can't be original if it's date code is after the engine assembly date which is something like 2 to 4  weeks later of the block/heads casting dates. There is a date code STAMPED into the block which is the engine assembly date.

Regardless of the C8 engineering number, it can't be original to the original build although it stems from recently after the original assembly date.

That doesn't mean that it is inappropriate for an early service part but that isn't what you asked.

It's more common to have the C6AE engineering number and that is what most would expect to find and although it may be possible to find a C8 pump with the right early casting date, that would be uncommon, but you are asking for opinions and for sure there will be conflicting opinions on this subject of 68 engineering numbers with early 67 casting dates that could have found there way into '67 assemblies.

To clarify, The C6AE marked pump is what is expected for example if in a concours venue. The date should before the engine was built .

Yes. If you are going to look for another pump, find one with the C6 engineering number.

There are lots of quality rebuilds around that have the "correct" (or as expected) engineering number and casting dates close to what yours would have originally had.

There will be others interested in what you have.

This is by no means a disaster.

Lets also remember the 7C6 could be a service part from even 1977 or even 1987 possibly if Ford continued to have them made that late
