Opinions on installing A motors in B bodies

The 340 Roadrunners were not uncommon considering I have heard of them and I am no fan of the B body snobbery.
snobbery!??? not near as bad a E body snobbery!?? ha...... I've had many of both and yes there is a basic difference in the folks! lol kinda funny to me.
I have a 67 i'm working on right now, I have had most every engine combo usually is stock form.... I want a BB in my B bodies, just me..... only exception is a poly in an early B, ( would love a built one!!!!!!!! with the new intakes, etc).....
