"that would truly help everybody." Actually giving up any info he has would go against his policy of not sharing registry members information.You can request a spread sheet all you want but its not going to happen. He has already answered your question but it wasn't the answer you were looking for. I didnt see where you say that all these cars were original one owner or survivor cars so how do you know that the engines are original to the cars???

"I believe you have simply lucked up on 3 cars with service replacement blocks and yes, engines were cast in bulk and not every engine was cast every week."

My thoughts exactly if what he is saying is true. This post just seems like a fishing post to get people to post or send their broadcast sheets to someone who has bad intentions in mind. Trying to fill gaps on their spread sheet so they can be the next guru.

Also the Autodynamics Challenger had a black painted top from day one. The race cars had absolutely nothing to do with the options on production line cars. The acid dipped story is true they did cut a roof off another challenger but thats where it ends. Sam Posey told me the story as well but never mentioned anything about painted roofs. The race cars and production cars were 2 completely different animals. Also the schedule for the SCCA races doesn't have anything to do with production cars.
