Now for the good stuff:

The block is a NEW DART SHP style block that is setup to accept stock style OEM roller lifter or even flat tappet. We use only a 351w SHP block with Clevor style main on all our blocks which is 1/4” smaller than its 351w stock style main. This smaller main helps reduce overall bearing speeds along with drag/friction and help prolong overall life. We also upgrade the blocks oiling system to put the oil where its needed most at all times. Even with the smaller mains the block and bottom end are still rated at over well 800hp so strength is never a worry here. (upgrades on hardware for block allow for 1200hp if needed) The bore is a std. 4.125 so no thin cylinder wall concerns either on this build. The block as in all our builds gets checked and machined all over as needed on these new blocks. The Mains are line honed and the clearance is set on all our builds and the lifter bores are honed as well. The cylinders are finish honed in our Sunnen CV-616 as always with honing plates for a perfect seal on your rings. We have almost no break in required on our builds. 

The Crank is a Lunati 4340 light weight forged crankshaft which can hold as much as 1800hp. Its a 4.250 Stroke crank with a 2.750 X 2.100 main and rod configuration.

    The rods a H-Beam Scat with floated pins and ARP 8740 rod bolts 6.200 long
