What Ratio are my Rockers?
I've got a June 2001 AU2 XR8 which I believe to the 200Kw version. I had look at my roller rockers the other day and found they were Yella Terras. I thought the 200kw engine had ford roller rockers. Have had a good look at the TB and there is no Tickford stamp on it as per the 220kw cars, am pretty confused. Is there any way of telling what ratio they are because I want to install a crane cam, but don't know which grind to get til I know what rockers I've got.
Any help would be much appreciated.
