Cam swap without pulling motor

I don’t love fast rate Hyd cams used with higher RR in general…….. so for me, that’s reason enough.

That being said, that cam is short enough to where I could see the 1.6’s making a little more power.
But I still wouldn’t use them.

I’d apply whatever $$$ the 1.6 changeover would cost towards bumping up the CR(head milling, thinner gaskets, etc).
