Welding Cast Iron? Repairable...?

[joedoh]

welding cast is possible, but not by the layperson. its about the prep, the broken part needs to be ground out for penetration, preheated to some crazy temperature, and welded while smoking hot.

sack54, the manifold is clamped to the block in that location, I dont think muggyweld would be a strong enough repair, but I am not that familiar with it. I did research it a bit for the windshield regulator on my 41.

I would guess you can find a 270 GMC intake manifold easily though, because its the exhaust manifolds that crack, so there should be some intake manifolds attached to cracked exhausts. alternatively there is a good aftermarket intake manifold still sold for the 270 that honestly would cost less than welding, but its set up for a four barrel.
