Exhaust Manifolds

Glad I saved all my 318 stuff when I switched to a 340. Only thing I remember tossing was the 2bl intake. Still have my original 340 stuff though for a '71. Need a bigger garage. Tempted to dig out the 318 and rebuild it. Unmolested '67 block.
All the attaching items (external) are the same with the 318 as on the 340, except the motor mounts. Trucks and vans oil pans are also different, must be changed out during a swap.
