Cam

[Austin in the Shed]

I'd agree with Ian,the only way to check a modified cam is to set it up in an engine, (Timing disk and drop clock on the valves).even then how it is likely to perform is another matter.I have a box full of them ,some have been fitted and quickly taken out again ( Done by well known regrinders).Most have too much duration to give any power low down,and one brand new one  £330 absolutely useless.
I personally prefer a good standard cam with reprofiled followers the best compromise for power and torque for a road engine.There is also an advantage of being able to up the compression ratio a bit.
