Now lets see; Yes, "generally speaking" changing the cam "will" affect cranking pressure. If the closing event of one cam is say, 13 degrees & the new is 9 degrees, both @ 050 approx,after bottom dead center then you will have more cranking pressure on the cam with the smaller degrees. Even just advancing a cam on the ajusting slots of 4 degrees can give significant increase in pressure. I have a programne download from comp cams that has a calculator for cranking pressure; haven't used it for a long time, but when you load all the specs of cylinder & combustion chamber in, plus stroke & bore, it gives the effective cranking pressure to the opening event of your intake valve. cheers, Mike.
I've been schooled. Thanks
Dakota for life!
