" This has me wondering if moving the 7120 4.0L head to the stroker and then finding a late model 331 casting for the mpg car would not be a good idea for a tad better fuel economy?

probably would.  does isky - or anyone else - make a mileage cam for
the 4.0?  199/232/258 ones might not upset the ecm...

"   I have the cast manifolds and could run small 2" duals for that old time flair too...

a tri-y setup and single pipe would probably be better for efficiency.
length of the y should probably be generous for cross-scavenging
resonance in the lower rpm range, but since it's daling with 3
cylinders on each leg it needs to be only 1/3 the length of single-
cylinder pipes.
