Expensive yes. High horsepower capable yes again. You guys will buy a 50
Year old block and buy a girdle, main caps, 1500.00 worth of machine work and have a block that if pushed hard can and will crack. So like many start over by looking for another 50 year old block. Sure this may or not be needed by everyone but some of us like to push the limits a little and not worry about driving over the crankshaft.
