G'day guys.
im just wondering how to go about how to find some good Cams for my 4age bigport engine? i will be doing cams when i get my 2.25 inch exhaust and 4-2-1 extractors done, and will have a cold air intake, and run 98 octane fuel all the time.
so what kind of cams should i be looking at, and where abouts do i buy them?
any opinois are welcom, thanks guys.

keep below 8mm lift and 264 degree duration and the stock ecu should just run it, any more and you're treading on thin ice with out programmable injection.

WADE CAMS. Do a search. i asked the same question. $440 for hks billet copies. I think mine are the 264's. They look sexy az 
They take visa too so its easy.

Check here (http://www.billzilla.org/ ) for what size is recommended and the power you can expect, then buy them here ( http://www.wadecams.com/ )

according to bill, i can use either 256 deg cams or 264 deg.(but no higher).
i guess my next question is, if i told wadecams that i need a set of 256deg cams for my 4age bigport. would that be all i have to say in order for them to get to work?
isnt there a difference between the intake and exhaust cams?

100/110 means that the intake is at full lift 100 degrees after TDC, and the exhaust is at full lift 110 before TDC.
(right?)
The 100/110 would give a fair bit of overlap and would be slightly dopey down low...would give best *power* though.

You would have to ask a specialist. And depends where max lift occurs on the camshaft.
