1970 Trans Am vintage SCCA race car

With all of the RA V stuff I have done over the years I have learned a lot about Pontiac Engineering projects.The interesting things about this engine lead me to believe George had a big hand in this at his place Leader Automotive.Tom Nell spent a lot of time there and there was a part of the shop most people were not allowed in.The block has a EUN number and then went to special machining to get the dist hole made to the RA V-455 SD size.Also the 4.21 stroke 3in main factory crank was one of im told of a handful made.In the last 25 years of doing this stuff I have only owned one.I have a 303 std deck V engine in my car now built as a 428.I have learned to never say never when it came to engineering stuff.I would love to have the short block.Tom
