Which Exhaust Manifold???

O.K., I've decided against the B/E/C body manifold, but still can't make up my mind between the 318 and 360 parts. The maroon who built this car used 2" pipe from the manifolds to the main pipes for about 2 feet (the rest is 2-1/4"), so I'm thinking that the smaller 318 manifold wouldn't make a huge difference anyway. I'm certainly NOT going to use the hi-perf 69/70 style. Too much $$ and this car would probably have a nervous breakdown if I used something that nice on it!

PAssenger side is staying the way it is. (Center dump late 70's truck 360)
