RRR,
Yeah I do 'get it'......have done, for a long time.....
This is what you said in post #21:
"That's 0.040" less lift at the LOBE".
It is not 040 less lobe lift, it is 040 less lift at the valve. Post #5 makes it clear, unless you think a FT cam for one of these engines can have 600 lobe lift....
