This 427 cubic inch short block has a 4.125 in bore and 4.00 in stroke. The dimensions are set with SCAT 4340 forged crank and matching SCAT H-Beam rods.
SCAT forged, 58-tooth reluctor wheel crankshafts are designed for street or race engines with substantially increased horsepower. SCAT crankshafts are precision-ground, heat-treated, shot-peened, inspected, and micro-polished at SCAT for superior tolerance control. SCAT crankshafts are also nitride-hardened for superior wear resistance, have straight-shot and chamfered oil holes, and feature lightening holes in all rod throws. These crankshafts also have a large radius on all journals for improved strength and wear resistance.
These H-beam connecting rods are the strongest SCAT connecting rods available. These SCAT H-beam connecting rods are perfect for supercharged and nitrous applications. These rods incorporate a special doweled cap for specific cap-to-rod alignment and are profiled with extra clearance for stroker applications.
Topping off the rotating assembly are Diamond's new R Series pistons which are machined with their newest and most precise CNCs. Among their features :
- 3D milling on piston crowns for ready to install finish
- Valve pockets designed to work with most aftermarket cylinder heads
- Offset pins for quiet operation
- Moly skirt coating for friction loss and skirt wear protection
- Side gas ports for better ring seal
- 2618 material for High HP-NOS-Boost applications
