A large cost-savings comes from our swapmeet finds: a four-bolt block and a factory steel crank. After cutting the journals 0.020/0.020 and align-honing the block, the crank was ready to drop in. A benefit of a stock-stroke crank is the reduced labor costs when balancing the rotating assembly, which required simply removing a wee bit of material from the front counterweight. Since the motor won't see much past 7,000 rpm, main studs are not necessary.
