Post by: UK Pete on March 14, 2010, 07:37:32 PM

I was comparing an F1 camshaft too an F2 camshaft and accidently got them mixed up, now i am totall confused which is which,
Can anyone help me identify which is which, ie is there any markings or numbers that help identify, or can i see from the lobe profile?

The F2/K7 camshaft has a slightly taller lobe height and is slightly fatter measurements are in the haynes manual. Cam height inlet 36.00mm exhaust 35.5mm. The F1 and K series appear to be the same at 35.86mm inlet and 35.36mm exhaust. Not a huge difference the F2 one is definately a wider lobe though to give longer opening time. Info subject to alteration by the real knowledgeable geezers on here though ;)
