I mostly agree with that Tim and sure wouldn't bank on appreciation, but it will impact resale value of a replica over say a small block, or just about any other engine choice. A side oiler could make the difference in a sale, deal or no deal.
As far as this 427 having a pedigree that traces back to an original, the most you could say about that is, "Rumor has it..." It will be virtually impossible to verify such a claim. That claim combined with "...the engine will be more valuable than the car..." is little more than a 'sales pitch' at best. Without documentation it don't mean squat, but makes a nice story for the local cruise in's. I guess it could be true. FIRST STEP, verify it IS a side oiler! If not, no way it originally came in a Cobra.
My friend has a date coded 1966 side oiler in his older Hi Tech. Rumor's were floating around for awhile it was really a 390, which was devastating to the owner. I checked it out, it's the real deal all right. I'm jealous, mine is only a service block, '68.
"Rumor has it..." my high rise heads and intake came off an original Thunderbolt from Texas, there date coded 1964. Kind of cool, makes a nice story at the local cruise in's. Could be true...
