Ecotec cam measurements

[maldotcom2]

I'm potentially buying a standard cam, however the seller isn't 100% sure if it's from an ecotec. Is there some quick measurement i can do to see if it's the right one?

i think the sequence of the lobes is different between buick and ecotech due to valve placement IE intake exhaust intake exhaust compared to intake exhaust exhaust intake take a look at picks of both cams you should see the difference

Yeah i know the lobe arrangement is different, im just not really sure what i'm looking at. Also is there a good place to get regrinds in sydney? Don't think it would be economical to post it interstate to Wade.
