CHI 3V 225cc Ford Cleveland Cylinder Heads.  67cc Runner

BARE PAIR - NO PARTS

The CHI 3V 225cc cylinder heads replace the older 218cc heads and are suited for use on competition and serious street engines of 400+ cubic inches in size and making up to and in excess of 650+hp. The new 225cc feature the same minimum cross section (2.4”) as the 218cc intake ports are designed to deliver maximum power and torque, for those people not concerned by RPM limitations, but rather wanting to make the most possible torque and horsepower for their competition to wild street power plants.

With just a modest increase of 7ccs, and with no change to the minimum cross section, we have managed to extract 340cfm from our new 225cc port without hurting the all important low lift numbers. Again the emphasis was on keeping the port as small as possible whilst increasing airflow as much as possible. No other Small Block Ford – Cleveland cylinder head on the market today has the same airflow per CC of runner volume.

By utilizing the advantage of a taller than standard, 4V intake port height, and downsizing the port to a mere 225ccs, we have created an intake port capable of producing in excess of 700hp, whilst still having the ability to make exceptional torque along the way. Just take a look at Jon Kaase’s winning entry in the 2004 Engine Masters competition. The engine had a peak of 700hp horsepower at 6500rpm and peak torque of 620ft/lb. All of this on straight pump gas and by a mere 6500 rpm
