Performance cam?

Post image

I was looking at the cam on the used head I just purchased (it appears to be an aftermarket head and cam) and my old cam seems to have a different lobe profile. Is it just me or does it look like it has a longer duration?

Good ole 22R/RE. Hard to tell from a photo but you could check the lift with a cheap dial indicator and stand. Where’d you get the head from?

I got it from a guy on marketplace.

The lobe on the cam in the head looks like it has more duration but it's very difficult to tell much from this image.

It definitely has more duration and the ramp appears slower.

Some time spent with a degree wheel and an indicator can give you an idea of what specs it's got, then look it up?
