Balancing

Electronic Balance Crankshaft (With Mallory) [+$152] **Please email or make an order comment giving the balancing specs. We require either the piston, rod, & wrist pin part # or the weights of each part. NR Racing must have these weights to balance the crank. Allow 1 to 3 weeks for balancing.

Description - Technical Specs
 
The 263-SKA Rotating Assembly Kit is made for Tillotson Blocks Bored to 76mm
The 263cc kit is made of a 76mm hypereutectic piston (same material as the 72mm Tillotson Racing Piston), EC's Pinnacle Forged Connecting Rod, and 58mm Ductile Iron Crankshaft.

For comparison, we should look at the differences in displacement among other small block engines.
  • 212 70mm x 55mm = 211.67cc (12.92ci) difference 51.45cc(3.13ci) 25%
  • 223/224 70mm x 58mm = 223.21cc(13.62ci) difference 39.91cc(2.43ci) 18%
  • 225 72mm x 55mm = 223.93cc(13.67ci) difference 39.19cc(2.38ci) 18%
  • 228 72mm x 56mm = 228cc. (13.91ci) difference 35.12cc(2.14ci) 16%
  • 236 72mm x 58mm = 236.15cc(14.41ci) difference 26.97cc(1.64ci) 12%
  • 254 76mm x 56mm = 254.04cc(15.5ci) difference 9.085cc(0.55ci) 4%
  • 263 76mm x 58mm = 263.12cc(16.05ci) difference 51.45cc(3.13ci)

The 76mm piston is very lightweight, which can help with the "balance" of the rotating assembly, improved acceleration, and increased durability. The piston journal's improved strength is that it is wider than the Tillotson 72mm piston and uses a longer 13mm wrist pin.

Note: This is a EC Carb part, not an NR Racing Kit!
