CARRILLO ROD SET of your choice, $50.00 off, if included with THIS order.

SUITABLE FOR STREET OR RACE PERFORMANCE.

Compression of 10.5:1 runs great on 90-93 octane pump fuel.
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 “squash” the mixture at TDC creating a hurricane to distribute the flames.
Our 81mm, 10.5:1 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.

We have been working with the people at JE on our pistons since 1978. Through our racing engine research and on track experience we have continuously modified our designs for better performance. We won four SCCA National Championships using the same pistons you can now buy off our shelf. Professional engine builders all over the world use our pistons.

Light Weight
Compression of 10.5:1 is measured with standard head of 112mm height and 1.4mm Reinze gasket. WARNING: .25mm milling = +.25:1 compression increase. Customer should submit actual head chamber volume for absolute accuracy.
Deeper valve relief to accommodate most performance cams.
Larger diameter valve reliefs will accommodate oversize 42.5mm intake and 38mm exhaust valves.
We also offer these as Piston/Liner Sets.
