I like this car's story and the documentation and Altho most of us would prefer an original engine, truly not a lot of these at the top of the Hi Po food chain retained their original engines. I don't think it should hurt the value too much as long as it is a correct engine. P.S. I really like the M22s that a lot of these COPOs had. It always surprised me that the YENKOs and ZL1s (most of them anyway) had the less HD M21s
