Cast Iron Welding/Brazing ???

[Hotrodpaul]

Crack is about 3/4" long on the inside bend of small block 527 manifold. With the spark plug shields in place it is not visible. I ground a nice v groove and removed most of the cracked material, then brazed it with a fluxed bronze alloy rod and it turned out quite nice after blending. I plan on blasting the manifold and painting with a high heat coating.

Any idea on where to get the best manifold coating?

Thanks, Paul
