318: too much cylinder head?

rumblefish, I know this is off topic. but are you having the same issue I'm having with the cursor disappearing out of the message box while you're trying to type?

RPM and engine displacement are relevant to each other directly.

Like it or not HP=TORQUE X RPM / 5252

therefore mathematically, all things being otherwise equal a 100ci motor would have to rev 2x as many RPM as a 200cu motor to pull the same air through the heads/carbs to make equal horsepower (at a much lower torque level)

Engines in their most basic form are an air pump. you have displace 20% less air per revolution you have a choice of performing 20% more revolutions in the same time period. or making 20% less horsepower.


re: driveline

Perhaps I could gain a tenth or two from changing my gearing and tires however it would completely remove the car's sleeper appeal.

I fail to see how increasing the average port flow in all used lift ranges by circa 30% could NOT cause a gain in net useable RPM and HP especially with a 114LSA cam.
