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

UP TO 20 HP GAIN?

This 3mm overbore increases displacement from 1570 to 1700cc.  With this 5% increase in displacement, raising compression from 9.5 to 10.5:1 and HOLE SPECIFIC APPLE BITE domes makes a huge difference in both street performance and race engines.

APPLE BITE DISHED DOMES offset from piston center makes more power with flame front travel distance absolutely minimized.  With compressed charge concentrated directly under spark plugs, the conbustion efficiency is vastly improved.  Also, the fat sides of the dame “squash” the mixture at TDC creating a hurricane to distribute the flames.

• Lite Weight
• Compression of 10.5:1 is measured with standard head of 112mm height and 1.4mm Reinze gasket.
• Deeper valve relief to accommodate most performance cams.
• Larger diameter valve reliefs will accommodate oversize 42.5mm intake and 38mm exhaust valves.
