Post by: Snowmann on March 29, 2006, 02:09:49 PM

Need to know the specs on the timing for the M42... i.e. when the valves open/close...

Local tech is a doink and wont disclose anything

I believe the cams are of a 252deg. duration.  10mm lift.  Thats all there is to it I believe.  As far as phasing, i would imagine the 2 are 360deg. off (all in crank degrees).

I need the timing specs, not the cam specs... I have found speculation on a Ti board that the intake is 16 BTDC and the exhaust is 12 ATDC

but need some solid information
