| Our 4.6 Racing Rotating Assemblies are what you need for a serious modular motor. These kits are complete with our ModMax Forged Stock Stroke 8 bolt crankshafts (check your flywheel for fitment), ModMax Forged 4340 H-Beam Connecting Rods (check the dropdown box for optional connecting rod choices), Keith Black, Manley, or ModMax /CP Forged Pistons (check the dropdown box for piston choices and pricing differences), piston pins, ModMax Plasma Moly File Fit Rings, and King High Performance Rod and Main Bearings. These kits are good for 600hp and UP depending on your connecting rod choice! With our forged crank, ModMax Ultra Billet rods, ModMax / CP pistons, and ModMax Stainless Rings we have customers making over 1000 horsepower without failure! This is the same basic combination of parts that Tim Matherly, Jim Breese, Sutton High Performance, Bart Tobener, Johnny Lightning and others use to dominate the competition.
If you are using 3 valve heads you must upgrade to the specific Manley or ModMax / CP 3V pistons in the dropdown box!
