Cracked exhaust manifold 396

[northerngmc]

Over the last couple of months I have noticed an exhaust leak on my 68 C20 with a 396, turbo 400. I thought it was probably a loose manifold or a collector gasket that was loose as the noise would go away once the engine warmed up.

Today I noticed that the left manifold has a crack in it!

Can an exhaust manifold be welded? I know it is is cast and this adds difficulty, but how much difficulty?

If I go shopping for another manifold how exclusive are bbc manifolds to trucks?

Any other reasonably suggestions?

The truck is fairly original and a bit of a survivor truck so I am not looking to go to headers or swap the entire exhaust system.
