I know i have been bothering a bunch of you over the past 2 or 3 days with question after question on cam shafts, i've read the manuals, websites, and i'm getting there. i understand the basics as far as aggressive cams will leave the valves open longer than stock and longer than mild cams.. also adversely affecting your idle (as far as making it more rough). right now i'm leaning towards some mild cams.. just looking for an even better understanding. a cam 'regrind' by definition is taking material off the cam shaft lobes?
here as the manual says,
standard height is 1.7360 inches for intake lobe (with minimum of 1.7281 inches)
standard height is 1.7560 inches for exhaust lobe (with minimum of 1.7480 inches)
here is a picture of the afar view of the cam shaft, and to the side is the profile of a lobe
now what i don't understand, is that if you're 'regrinding' the cam, you're removing height from this lobe... wouldn't this limit the stroke distance and how long each valve is open (lift and duration)? where am i fundamentally going wrong with this guys? i know i'm not a machinist, i just would like a better understanding as far as what a regrind cam is going to provide me? is a regrind replacing the lobes of a camshaft with taller one's.. are the angles just changed on the shaft itself? hopefully someone can point me in the right direction
peace
