Original motor vs. replacement

[djunod]

Don't leave out reproduction POP's also... I've seen at least 2 lately.

(edit: I see you did mention that... only with the longer spelled out Protect-O-Plate...)

Jeff,
I think I'm feeling the same pain. Craig's original criteria were:
"I'am defining the original motor or block as follows:

1. The one it was born with from the factory.
2. The one installed by Chevy Dealers such as Yenko, Motion, Dana, etc., that went to the first owner.
3. The one installed as a warranty repalcement."

I guess it would be difficult to know if an engine was the ACTUAL one installed in the original conversion....

And that statement brings up my next question. How DO owners of dealer converted cars determine if they have "The" motor that was dropped in? Obviously, this doesn't apply to the COPOs

You dont! Unless that dealer kept records of it; Consider all the Dana changeovers...All mostly were VN cars. How many Camaros,etc did they change? What Chevrolet dealer in all of the US didnt have part #s or ordering capabilities to any engine available from GM! Why couldnt I have walked in, slapped down a payment on a base X44 car at that time and pay that dealership(dealership willing) the extra money and fees to R&R any motor and install any L88 available at that time?

It doesn't matter whether they are '68 Baldwin-Motion Phase III Camaros, ...

But since the Motion car by definition didn't have it's original engine, as Joel had to take it out to make it a Phase III,

Unless it was a Phase III 396 car, in which case it would have its original L78. Isn't JoeG's Chevelle a Phase III 396?

[Mr70]

Yes it is.

I don't think that the warranty replacement would be considered an original motor. If you purchased a new 1967 Corvette and the motor exploded within 11 months of ownership, chances are that you would now have either a short or long block warranty replacement motor. It may or may not have CE stamped on it depending on the damage and availability of parts. It would, more than likely, have a block and possibly components that could have part numbers for a 1968 vintage car and the motor may have a casting date up to 11 months later than the assembly date of the car. If someone offered me a 1967 435 Corvette with a replacement 3904351 four bolt block with a casting date 30 days before the assembly date of the car or a CE motor with evidence of factory warranty replacement, I'd choose the correctly dated block. This is just me, I think there is value having a replacement motor of correct part number and casting date vintage. People can always say a replacement motor is a warranty replacement motor and this would be very hard to prove.

Did the green Yenko in this auction have "The original motor"?...or was it a "Matching number replacement motor"?
.....taken from a previous post about the Yenko sold at Mecum Auction....
...."A '69 Rally Green Yenko Camaro sold a few weeks ago in a Houston Auction for $247,500 + buyers fee. I think the buyer's fee is around 8% putting the selling price around $267,300 WOW! "
.....I thought someone said it was a "Matching Number Motor"....which is not always the original motor!
