Earlier manifold looked rounder and less bulky. Any difference aside from the ridge? Any reason for the change? 6994085-1231111424.jpg (80 downloads) 1973 Charger, former SE, former auto I'm not trying to be difficult, it comes naturally....

So the ridges are to hold the stove in place after the (aside from it being bolted onto the manifold)? Anybody ever weigh the two for a difference? Also no real performance difference from the earlier style is there?

Andy made 550 horsepower from an alum (eddie iirc) headed 470 with those manifolds/3" mandrel headpipes. Overall visually they look like they'd flow the same or very near the same on the inside passages live every 24 hour block of time like it's your last day on earth
