Picked up another Pontiac 455

I have a friend that can weld anything man ever created, he brazes cast iron and I've never seen it fail.

did a search on brazing cast iron and came up with this...I have never seen it but there are guys posting on forums using it so I guess it works.

you can get 1/2 lbs of the cast iron rods for $30 on ebay

See, I'm not just an old guy rambling on.
I've owned something north of 140 vehicles, a dozen boats, about the same number of motorcycles, I've built more Pontiac engines than any other, by a wide margin. Done a bunch of LT1 swaps, a couple of LS swaps and just finished converting one of my several garden tractors from manual to hydrostatic. I may not know much about anything, but I know a little about a lotta stuff! :lol:

That's one of my favorite sayings!

I guess I stand corrected! We don't repair cast because it's more cost effective to replace I suppose. As for the manifolds, I'm leaning towards the RA manifolds anyway.

You ain't alone in the world, a lot of very knowledgeable people don't know about brazing cast.

I read about welding cast and it said the whole cast had to be heated up and then welded with a stick, then covered so it would cool down slowly.....and it went on to say that the welded cast would be the weak link so it wasn't worth it in my eyes. But this brazing cast is interesting and i'll see if the welding guru on the race team knows about it.

I'm dating myself here, but I repaired a huge cast iron frying pan for the wife many moons ago with a "Solid-OX" set. The handle broke clean off and I brazed it back together, still holding up fine some 30 odd years later. What is even better is the nickel-silver rods they had. For the newbies, Solid-OX worked by burning a thick rod in a sealed tube and oxygen was generated and fed to a regulator then mixed with propane. Not very good for welding, but great for brazing. Laughable now, but that was the 70's.

if the frying pan is still holding up that is a good thing, it means she probably never hit you with it....

How do you think it broke in the first place?
