Yenko take out motors

[Stefano]

The Yenko Nova engine which I have has no specific designation other than GM's CE stamping and its sequence number.

You would think there would be at least a couple of documents to verify which engine went into a particular car.

You should have at least a parts invoice charged out against a dealers internal work order, very standard procedure.

If I recall ,GM did warranty their over the counter short blocks and a dealer would want to keep track of them.

It would be great to see documents surface to help verify and document the engines.

I did run accross someone (?) who had an NOS L72 short block with MP and its own sequence number in addition to the standard GM stampings. I didn't know what the stamping meant?
