We offer a multitude of machining services direct from the factory! When ordering a block, it is the perfect time to include our value-added machining for the customer in a hurry.
Obviously, dealers have the opportunity to drop ship blocks to their customers that include this machining, not having the expense of 'double shipping' to the customer and making some coin in the process.
The cost is typically less because there is not a setup charge if the additional machining is identified at the time of order. Otherwise there is a small setup charge.
