New engine is gonna have some blow-by till the rings seat. How is the vent routed, straight down like original or over the engine and down the back?

Run it hard and don't do touch and goes.

You could also modify your breather elbow like this one. It will get a little less "splashing" of the oil off the crank.
By the way, your Cub looks great!

We modified the tube to a length more similar to this one and now we got normal consumption. Or the rings are starting to seat.
Now all I need is the vibrations to tone down a bit. We turned the prop 180 and not much change. Going to try to find one to borrow just to test it out. Maybe take off scull cap spinner.

A few quick suggestions to look at for firewall-forward vibration:
propeller track
lower cowl panel to airbox clearance
muffler shroud to cabin heat box clearance
oil sump to engine mount clearance if you have the newer style kidney
engine mount bolt torque
Is the cowl structure rigid when the cowl doors are unlatched and open? If not, there may still be enough flex to induce a vibration even when it's buttoned up.
