Scat Connecting Rod Selection
Rod selection for this build was fundamental. Just as we went with a heavier duty option for the crankshaft for durability reasons, we matched that move with Scat’s Pro Sport 4340 forged H-beam connecting rods (PN 6653522A) with doweled cap alignment and a 7/16-inch ARP 2000 rod bolt upgrade.
Dart 18° Big Chief Cylinder Head Selection
We selected a set of Dart 18° Big Chief cylinder heads for this project. They are offered as cast or with your choice of Super Mod porting or Full Port CNC porting. To match our application we chose the Super Mod porting configuration.

This build uses a Scat Lightweight Pro Comp forged crankshaft with a 4.250-inch stroke (PN 4-454-4250-6385-2) and a set of eight Scat H-Beam Pro Sport rods with a 6.535-inch length and a ARP 2000 rod bolt upgrade (PN 445425-2). The 4.250-inch stroke was chosen to complement the 4.600-inch cylinder bore.
