it would be really cool to see two pictures if possible, from the side of the motor with both of the Durango manifolds on. it sure doesn't look like they clear the firewall. can you take a few minutes and do that for us all.
The right side manifold that's pictured bolted to the motor is a truck manifold.. scrap.
The manifolds on the bench are the same manifolds that 408 Swinger is running on the 73 Scamp. Left side is Ram/Jeep/Durango and the right is Jeep/Durango according to the part # interchange.. So I only had to buy 1 (right) manifold since this was a truck engine.
I've pushed the 5-7 to the side for now (for sale) since I'm now doing a 6-4, but if you'd really like to see them bolted on a block, I can stick them on and grab a few side shots. I have them listed on FB MP right now, since I won't be using them anymore.. The 6-4 is gonna need Headers
