340 dyno chart thoughts
That's what i just said. Advertisements used to be all over the place until a standard duration measurement was implemented. Now they all advertise at the standard. The standards came from SAE. you DO know what SAE is don't you?
Lustle, you need to get it through your skull that a camshaft's specs are determined long before you install that camshaft into an engine with valves. They design a camshaft using specs and they produce the camshaft using specs.
One day if you ever care to look, you will find that duration is measured as a specified lift for a specified number of degrees and this is measured @ the lobe/lifter, NOT the valve.
Think about that for a second. I'll just repeat it. Camshaft duration spec has nothing to do with the valve. It is simply measuring... the camshaft. you know.. the long bumpy thing? It actually still exists when it's not installed in an engine and can even be measured that way! Fancy that!
Now, getting back to those SAE standards we talked about.
The standard for measuring duration on hydraulic cams is 0.006" of lift AT THE LOBE.
The standard for measuring duration on Solid cams is 0.020" lift AT THE LOBE.
I know that thinking isn't your strong point, I've explained the difference lash makes in how a solid cam's duration specs translates to actual valve timing TWICE now and still you don't get why you can't compare a hydraulic to a solid using the same 0.006" specs. So this time i drew you a picture, Good luck!
