The Eagle Chevy Street Performance Rotating Assemblies offer great value, performance, and reliability for engines producing under 500 horsepower. All kits include quality components including an Eagle cast steel crankshaft, Eagle SIR I-Beam rods, Speed Pro hypereutectic pistons, Hastings rings, and Clevite or King bearings!

Notes:

  • Assembly part numbers that begin with “B” are balanced by Eagle and require no additional balancing.  Part numbers that do not begin with “B” are unbalanced assemblies and must be balanced by a qualified machine shop before use.
  • Internally balanced assemblies do not include flexplate or dampener.
  • Externally balanced assemblies include a 153 tooth Pioneer flexplate for 1pc seal applications or a 168 tooth Pioneer flexplate for 2pc seal applications and a harmonic dampener.
  • Internal Front/External Rear Assemblies include a 153 tooth Pioneer flexplate.
  • Eagle Specialty Products reserves the right to substitute pistons due to availability.

What are the torque and horsepower ratings on these

Asked by: Mrcruz28
There are too many variables to list the HP numbers on this. it will depend on what you are using now, and realize that these are flat top pistons and may be similar to what you have now.

Do any of these kits come with standard pistons

Asked by: Dukevo1
No, you will need to bore the block to install these kits.

I'm curious, what thickness head gaskets were used to achieve the listed compression ratios?

Asked by: Bigbaldy
Eagle normally will use a .040 compressed thickness measurement to rate the rotating kits compression.
