Thats the EFI windsor range, im pretty sure it's the (mild touring cam profile.)

ring crow cams and ask for Johnny Marshall, those guys spent a fair whack of time developing that cam for the AU (if that's what asking about).

He'll have all the time in the world for you. promise.

Thats the one there. The "mild touring cam" is the 200kw camshaft.

To clear the specs up they are.

Duration @ .050" = In. 203deg, Ex. 209deg.
Valve lift (1.6 rockers) = In. .455", Ex. .455"
LSA = 118deg

Now im pretty sure that lift spec is with 1.6 rockers which would make lift with 1.7's .483".

Now to go off the subject here i'd say the 200kw AU XR8 engines must have had 1.7 rockers aswell, which is what alot of people have found.

Sweet as jeff, ;)
But wasnt the 200kw more aggressive because it only had the 1.6 RR's
And the 220kw got 1.72's and head porting by yella terra?

I thought so too .the 621339 cam was the 220 and the 200 was the 62757. Ive lost the email from Crow cams ,as said a quick call will set you straight

220kw cam specs are as follows;

Cam; specs 220
intake valve timing 16/72
.050" 203

Correct. According to Crow the AU 200kw camshaft is the 62338 run with 1.6 rockers (the debate is still open, some recieved 1.7 rockers, some 1.6s), the 220kw cam is the 62339 and was used with 1.72 Yella Terra rockers.

yeah but everyone thinks the cranecam rollers are 1.6, when they were 1.7's. According to yellow terra the change over was purely due to a reliability issue with the crane "cobra" rockers whereby the roller tip pin slides out cause they never had a circlip grove cut in them, i have had this happen on 2 of the AU 200kw crane roller rockers i have, and i have checked the part number with crane and they are listed as 1.7's.

[XH5LWEPN]

Yeah thats what i was thinking, they HAD to be 1.7's, the lift with 1.6's is just too small.

Dont worry about the cranes only mate, you should see the Yella Terras from the 220's after 150,000kms aswell, not a pretty sight.

Remember me? I'm one of those people.........I tried to tell someone else that in another thread. Sheesh. In the process of trying to find out exactly what model engine I had, I got a DTI and measured cam lift, valve lift etc and guess what, 1.7 ratio yella terra rockers on a 200kw motor. This was in my ute which I have had from brand new. Not saying all were like that, just saying that some ARE definately like that.
