Chevy 454 Big Block Stroker Kit
Rotating Assembly

These kits are built using a
454 Block and Heads

At RPM Machine we are pleased to be able to offer you the ability to customize your Stroker Kit right online without the hassle of contacting customer service.

The following options are available to you in the shopping cart:

1. Upgrade or change the stock pistons that come in the kit for a forged (Silvolite or TRW) or a Premium Forged Piston (SRP or Mahle)
2. You can add rod bearings, main bearings and piston rings. Rod bearings are Clevite 77 P series bearings in all 500 HP kits and H series bearings in all 750HP 4340 steel crankshaft kits.
3. You also have the option of having your Stroker Kit balance prior to shipping. All external balanced rotating assemblies will include a new damper and flex plate with the balance work. If your assembly is only externally balanced on one end or the other the kit will only contain the external component needed for balancing the assembly.
