NEW SQUISH/DISH DOME MAKES MORE POWER

  • Dished dome makes more power. Flame front travel distance is minimized when compressed charge concentrated directly under spark plugs combustion efficiency is improved.
  • Tall shoulders of dome “squish” the mixture at TDC creating a hurricane to distribute the flames.

Compression of 11.5:1 is measured with standard head of 112mm height.

Our 81mm, 11.5:1 1750 piston set was developed while winning three SCCA National Championships. The only change is the larger diameter valve reliefs to accommodate the vintage racers that are not confined to standard valves. The standard 80mm liners can be bored to 81mm.

FEATURES

  • Includes standard wrist pins (109 grams) and conventional Ring Set. (SEE UPGRADE LIST.)
  • Lite weight.
  • Compression of 11.5:1 is measured with standard head of 112mm height.
  • Deeper valve relief to accommodate most performance cams.
  • Larger diameter valve reliefs will accommodate oversize 42.5mm intake and 38mm exhaust valves.
