340 or 383 for 1968 Dart

Thanks. I was hoping for a similar comparison, with the aluminum bbm heads compared to a similarly equipped iron head small block.
I wouldn't consider a aluminum intake/head/water pump/ housing, header, comparison to an all iron (including intake and exhaust manifolds) small block fair. Would be informative, though.
I've always wondered how much, ACTUALLY, the supposed weight difference really "hurts handling"
Not one of my six mopars has power steering, so handling does not enter my conversation, normally.
