Not to mention the base circles are different between the mechanical valve and hydro valve engines, if you were thinking of going that way. It could work, but from what I gather over 50-100k miles the vibration transfered into the valvetrain will wreck it and the cam.

The info in that link is comparing apples and oranges.. There is no info there on the hydro 1.6TD cam which would be the one to compare against an AAZ cam.

Very good point sir. You should measure the hydro cam and get back to us.

been running 1.6td hydro cam in my aaz head on 1.6 block for 15k miles, cam and lifters looked great when resetting the timing yesterday.

I have a hydro 1.6TD cam lying around, but don't have a Cam Doctor available, sorry

I just read somewhere recently that someone was running a 1.9l cam in a 1.6 and thought if it was a good mod. all of us would have installed one already.
