12.06 in a 4000 pound car with a 6 pack and set of headers on a 133 thousand mile pullout from a 69 imperial...original timing chain and all. That was a tough `ol dude....It was in the car for several years and finally gave up the ghost from several bottles of nitrous being ingested
That block and crank are still alive today in my current blower combo
