O-360 vs IO-360 dimensions

Hi folks

This has probably been discussed many times

I currently fly an Exp Super Cub, still busy building my 8. I’ve been looking into installing a fuel injection engine into the Cub for a while now. I’m in the process of buying an IO-360 M1B for the -8 project from a friend of mine, and I’m considering installing that into the Cub since the RV is still a long term project.

I currently run a carbureted 320, and love the original look of the classic filter dome of the Cubs, hence my question: what is the height difference between a carbureted 320/360 from the bottom of the Carb to lets say the top of the engine or to the centerline of the crankshaft compared to a horizontal intake IO-360? I believe it is more compact if you look at vertical intake cowls compared to horizontal intake cowls, but how much?
And then - what real word weight difference is there between a carbureted 360 vs a FI 360? Keep in mind most guys run metal props, magnetos etc, I’ll be going with composite prop, composite cowlings and electronic ignition
Thanks

If you get the Lycoming Operators Manual for the engine(s) in question it lists all of those dimensions. Will be very helpful / useful information for operating that engine as well.
