Description

Scat engine rotating assemblies are available with either a high-quality Scat forged 4340 crankshaft or Scat's Series 9000 cast crankshaft, plus I-beam or H-beam connecting rods with 7/16 in. or 3/8 in. cap screw bolts. For maximum power and reliability, Scat adds rod and main bearings from King, Federal Mogul, or Clevite 77, depending upon the application—and pistons and piston rings made by such well-known manufacturers as SRP/JE, Ross, KB, Mahle, Diamond, and Probe. Kits with cast and standard forged pistons have standard rings; kits with premium forged pistons have file-fit rings. Nearly 800 Scat kits are available; order the package tailored for fitment with your engine application.
