The Honda Prelude has one single cam engine out there that needs more recognition that it gets.  Its the single cam F22.  Most preluders prefer the dual over head cams to the single over head cams.  Here is an article that will tell you what they don't know.

• Bore × Stroke: 85.0 × 95.0 mm
• Displacement: 2156 cc
• Valve Configuration: SOHC, 16 valves, non-VTEC
• Compression ratio: 8.8:1
• F22 A1: 125 hp at 5200 rpm 137 ft•lbf  at 4000 rpm
• F22 A4: 130 hp at 5200 rpm 142 ft•lbf at 4000 rpm
• F22 A6: 140 hp at 5600 rpm 150 ft•lbf at 4500 rpm
• F22 A7: 140 hp at 5900 rpm 145 ft•lbf at 5000 rpm

This engine has been severally over looked when it comes to engine building.  It has a major lack of support, and that is the reason why this single over head cam engine has been left out.  What people just don't know is that single over head cam engines can make just as much, if not more power than dual over head cams.

Looking at the F22 engine, you will notice that it has 1 camshaft.  This is more typical in the early 90's but today its becoming rare.  The advantages of the single cam are slim.  It has 1 camshaft so the motor can work less, so that it can put out more power.  Its simpler to work with.  Adding an extra camshaft can complicate things more so than one single camshaft engine.  Remember the saying, keep it simple stupid.

This F22 engine has the ability to make over 400 N/A horse power.  That is a big N/A motor.  If you were to use a nitrous system on a motor that size, you would be putting out around 750 - 800 horse power.
