I did a similar thing like that by brazing many years ago....put it in the cooks oven and baked to 350 to 450 or so then went to work on it....was still OK the last time I saw it. I was more concerned about paint adhesion but I had little to lose in the deal. It's a touchy subject around here when I come in from the shop headed for either the cookstove or the deep freeze. 😂



The oven was a good idea, putting it back in the oven to let the temperature even out after brazing wouldn't be a bad idea either.

Chopped Liver, I've got my own rope thank you very much.

I'd tell you as long as it's clean and scuffed you should be able to achieve paint adhesion. We painted over leaded fender repair jobs for years. What's the melting point of lead. 1200* would be high enough for most applications.

Be careful when you follow the MASSES......sometimes the "M" is silent.

Could you braze the manifold adding filler then use a die grinder to fine tune the shape?



I thought about brazing but wondered about the risk of heating it that hot.

I can't remember ever being asked this question in the past but two customers asked at the show this past weekend.

Are  you looking for a new product or something to fix what you have.
Six cylinder flat head engines run in the 250/300 almost at an idle.

I have seen some hi-temp (1500) cements listed in Applied Technologies catalog, don't have it here to look up, but I think they were Devcon products.

That looks like a good candidate, just need to find out which version would be best and cost.
