Fermanta Posted August 3, 2011 Share Posted August 3, 2011 Hi lads, I need a cam shaft for my 1980 2.0SR Ascona & remember a thread on here where someone said they were different from GTE cam. I believe the difference was a groove somewhere to do with oil flow? Can anyone shed any light for me please? Cheers Fermanta Quote Link to comment Share on other sites More sharing options...
monzta Posted August 3, 2011 Share Posted August 3, 2011 Never heard of it ? Sportcams are identical on both GTE and carb fed engines, so i dont think theres any issues there.. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted August 7, 2011 Share Posted August 7, 2011 yes there are differences. an early engine has a groove in front cam journal to allow oil up into the rest of the head whereas a later cam doesnt(it has a modified oilway drilling)you can fit a early cam to a late engine but not vice versa.if you find a cam check that it has a groove(unless of course that you have a newer cylinder head fitted anyway!) a gte cam has a 2 degree advance on all its angles but the same duration spec so allowing for a slight chain stretch which your engine may have this could very well bring the valve timing back to standard anyway so should be ok.
