I'll bet  this could be argued every way that is possible.  I don't think
there  is very much difference and I'm pretty sure it would depend on what
other  engine modifications were involved anyway.


I'm not sure that a F4B can support much more than a stock head, low cfm  
4bbl combo, but it is period and Tiger correct, of course, and should outperform  
the FoMoCo cast iron equivalent from that era  :-)
 
I would love to see a dyno plot of the Performer vs. F4B on that same  motor, 
though...my guess is that the "old school" manifold would get smoked, to  say 
nothing of the option of moving to the Performer  RPM.
