wetwilly5757 I thought of JB Weld and I've used a lot of it through the years. I didn't know how successful it would be when the manifold heats and contracts. I was going to get it brazed, but needed to use the truck and sealed it with HiTemp Silicon and that works for a while then I need to scrape off and reapply.

I may try using the intake from the 1964 230 because I am leaning towards using the 292 4wd, the decision maybe to use most of the equipment off my 1977 K20 and don't know whether I'll use the 292 or 350, both should bolt to the Auto Transmission/transfer. The question will be how much restructuring to change from frame mount transfer of 1964 to Trans mounted Transfer of the 1977.

Question?? - I know the exhaust manifold outlet looks bigger from pictures and it is 3 bolt. vs I believe the 230 by memory is only 2 bolt (?probably?), I should be able to get by with using Carb and intake from the 230 if mounting bolts are different for the carburetors. The two manifolds should still bolt together ?Shouldn't they?
