"Light" is sort of a relative term. There are FE flywheels that weigh down in the single digits. It's pretty certain they will not work for you. I'm not sure what a Ford iron flywheel weighed but it was probably somewhere between 30 and 40 lbs. Between there is a lot of territory. I put a 22 lb flywheel on my FE and it revs very quick but drives easy in traffic. When I first put it on the road and before I was accustomed to the shift linkage yet, I made several 3rd gear starts by mistake and it just took off with little more effort than 1st gear. I suspect what will work best for you is something in the middle of the two extremes.

Also - I'm not familiar with SB Fords, but my slave cylinder mounts to the engine block on my FE. Is there not a similar option for the SB Ford? As often as hydraulic slave cylinders seem to fail - the thought of having to pull a transmission to replace a hydraulic TO bearing would not sit well with me.
