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?

OK folks, Heres another twist on this. If I were to have bought one of thses cars new in 68-69 I would think that since I paid for the car itself along with the extra $$ to have the car converted, I would think that the engine that was removed should have also went to the person who bought the car new. Kind of like when I get repainr work done on my wifes car. I want the old parts back. Keeps the H#n#a dealer here honest. I also get to see just what was replaced

In those days, the salvage value of the engine taken out was already factored into the price of the conversion.

The response from Joel when asked if Motion added any MP numbers or designations to the CE blocks was "not normally". That confirms what I have observed on the blocks in my Motion cars.
Also, my recollection of "back in the day" was that we didn't care what number was on the block, and, if a motor needed replacing under warranty, so much the better. Nobody gave much thought about the original block adding any value, especially 30+ years down the road.
