I was away from racing for 22 years or so and decided to build a stocker. Since I was coming from super-gas it was a whole new experience for me even though I was building an engine for my stocker from the same engine family I was using in super-gas. The only new items that I noticed was the change to the roller rockers and solid lifters (which I had already been using) the rest of the build was straight out of the rule book with attention to the approved products pages. The only thing I wish I had from the racing I did 20 some years ago would be a trans brake and a pro tree. That's actually easier than the .500 count down
