a question relating to 'THE EA81/82 BIBLE' as its being toted
what cams/ cam grind do you or know of being used in the EA series of engines??

ive heard of a race grind, not really sure on what the specs where
the other one is a hillman hunter grind

what else is there??

Camshafts generally come in "stages" you have your standard grind (factory) then usually available via the aftermarket are.. stage 1 cams, stage 2 cams and stage 3 cams. These vary in profile of the lob.. stage 3 for example has a very large high and long duration lob.. and they decrease down until you get back to standard.

I've never heard of the grinds you mentioned,, I'm thinking that is old school drag racer boy talk.. hilman hunter = slow grind (or close to standard)

Here's a link to Tighe cams in Brisbane.

just what justin said on another post
his freind had a EA engine with hillman hunter (the car) profiled onto his cams

after eading tighe cams there isnt much that can be done, no stages at all, only an inporved turbo cam

Forget about stages, that's old hat.

Lift, Lobe centres, and .050 timing figures are the keys.

Aim for high intensity, smaller differences between .050 and "seat to seat" timing, gives the best of both worlds.

Can't run big cams with low compression and vice versa, depends also on available fuel octane.

Here is a pair of s/h cams for a EA82 for sale
