Parts Bin (SEMA Edition): SCAT 9000 Series Rotating Assemblies

You can’t go wrong using a Scat Rotating Assembly as the foundation for your next engine build. And with 767 different kits available, SCAT makes one for your engine—including a Series 9000 rotating assembly!

Ideal for street use and mild race engines, 9000 Series cast cranks are a big step up from OEM. The cranks are made from Scat’s proprietary 9000 steel, then precision-ground and micro-polished.

Depending on the kit, your Scat rotating assembly will come with standard, I-beam, or H-beam connecting rods; King, Federal Mogul, or Clevite 77 bearings; and a piston and ring kit from SRP, JE Pistons, Ross, Keith Black, Diamond, or Probe.

Scat makes rotating assemblies for standard and stroker combinations for these engines:
• Small and big block Chevy, 348-409
• GM LS
• Small and big block Chrysler, Gen III Hemi
• Small block Ford, 351C, 429-460, 352-428, Flathead V8, and Modular V8
• Pontiac 400-455
• Jeep 4.0L inline six-cylinder

    drag racing on a shoestring budget.

  2. I build a 383 cid using Scat rotating system. Love it and want to do it again in my 1933 Chevy.
    I’m 67 and still build my own hot rods.

    I have a 460 bored 30 over to 466. I would like to build a 900 to 1000 hp engine to run on pump gas if possible and drive on street and race at drag strip. I have a 85 foxbody hatchback,

      Rick…your Ford 460 is a popular platform for building the power levels that you are looking for. It will take a well thought out combination of parts along with some extra cubic inches. The Scat 9000 series of rotating assemblies is fine for street and mild strip builds but it uses a cast steel crankshaft which might not be adequate for the power levels that you’re looking for.

      Scat has several stroker rotating assemblies that feature forged 4340 steel cranks and H-beam connecting rods with premium forged pistons in 0.030” oversize to fit your production block. The 521 cubic inch combination is a proven performer at the power level that you seek. Scat has other displacement kits available using the .030” pistons for your block. They’re easy to locate using the Summit search feature. Good luck !
