Andrew, OK lets see if I can remember this one
A is torquer cam for trucks, utes etc B, B1 and B2 are single carbie, twin Hitachi's, twin Mukinis in that order C cams are later model pollution motors, C1 from L20B is supposed to be much the same as B1, but they have a different number so they must be different in some respect. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:membersozdat_owner@;datascribe.com.au]On Behalf Of Andrew Greenbury Sent: Wednesday, 6 November 2002 12:11 PM To: [EMAIL PROTECTED] Subject: RE: cylinder head replacement cont... Thanks Terry - yep will do check the vol. I was starting to get disallusioned with my head removing yesterday after the 2nd one :) One thing I cant find, and I know its come up in the past but cant locate it in the archives, is does anyone have a list of all the factory cams (A, B etc etc) specs and what applications they are useful for etc?
