CNC Machined Dart SBF Blocks

ZSR offers fully CNC machined Dart blocks that will arrive at your door ready to assemble. We go through these blocks with a fine tooth comb and start with the smallest cylinder diameter possible to be able to take everything to true "blueprint" specifications. Just because they are new, does not mean they are perfect out of the box. We have the ability to make them perfect and give you a flawless product. Each block comes with an inspection report so that you know exactly what you purchased. 

-Blocks are deburred by hand

-Oil Returns Chamfered 

-Deck is surfaced, cylinders bored to blueprint, and lifter bores machined (if requested oversize) on our Rottler F69A CNC 

-Cylinders are finish honed on Rottler CNC Hone with aluminum torque plates installed with ARP hardware. Surface checked with profilometer and TraceBoss Software. Piston to wall clearance and cylinder finish are done for your specific application and fuel.
