Along these same lines, how about a "New Tool" ? Pick a couple of popular engines, SBC,Pontiac,Buick Nailhead, Ford small block,maybe a Ford or Chevy big block, an RB MOPAR and do a three tiered parts pack.1) Old school '50's-'60's 2) Middle '60's-'70's 3) something new '90's-up.at each level include some things from that era, carbs,manifold, air cleaner,valve covers, headers? These things all seem to change through the years.
