Off the Cuff....

One of my more fun engines when I was too ignorant to know better...lol.
stock '69 340 - factory cast pistons. New rings (stock replacement), small Comp cam (passed emissions for a few years), stock Thermoquad, headers, Jacobs ignition, 175hp NOS system in my '74 Barracuda with a 4sp and 3.23s. Pegged both the rally speedo at 150, and the factory tach (7500) at various times during nighttime commutes to tech school and street racing. The pistons lost some ring lands when i ran out of gas and a nice old lady gave me the gas for her lawnmower to get to a gas station... I had to climb out of a valley and it was nasty fuel.. The engine pinged like mad doing it and that was that.
I still have the baggie with the parts of the rings and pistons hanging above my work bench as a reminder.
