Stock manifolds, can they be cut & welded?
This is probably a dumb question but I'm just curious if anyone has tried this with any success? I want to cut the stock flanges off and put v-band clamps on for my turbo build.
Any input would be greatly appreciated! Thanks!

There's a guy on tech that had it done by a professional for his turbo Chevelle. He said it they pre- and post-heated it, along with grinding a nice bevel on the manifold.
My brother and I were in a rush when we were putting the turbo kit on his Chevelle, so we just welded pipe directly to the manifold. I'm curious to how it's going to hold up over time...

I put a 2.5" v-band on my drivers side manifold for the crossover to the KB turbo manifold. Got the welder at work to do it, preheated, then stick welded. I can't remember what type of rod he used, it was something different, very thin, and then post heated for a few minutes and left it covered in a bucket of sand to cool. I don't have a lot of turbo miles but so far there are no leaks.

To weld cast iron, you need to pre heat it to 450* , verify with a heat pen from a weld shop, and you need to use a high nickel content arc/stick rod. If you dont it will crack.
We have welded ductile iron at work this way, just needed to let it air cool, no post heat needed, this was for water pipe and it worked fine for us, no leaks haha.

Cut and put a bevel on it, need to pre heat and i usually weld it with either a nickle rod or a 309l filler, then wrap it for a slow cool down. I just use and old welding blanket i have and wrap it real tight and leave it for a couple hours.
