I didn't "build" my car.. I had a '67 MG for sale and a kid offered me almost exactly what I was asking.. and his car.. He told me it was built to the max - but I didn't know how much until he handed me the receipts along with title.. In short, it was a 406 tri-power - balanced, blue printed.. dual points.. ya da ya da.. Had a ball with it.. sold it.. wish I had it back..
