Pitting on intake
« on: December 04, 2017, 04:11:30 AM »
Can someone give me their input/expertise on this manifold. It's correct for my Camaro and I have the correct carb for it as well (I'm goin to put a date correct 350 in it), but as I'm not a very experienced mechanic, is the pitting on the manifold going be an issue where the carb and water neck mount? And if so, can it be fixed? Or will I need to find another intake? I know that there is a fix to plug the two extra holes, I'll do that, with either brass plugs or a 3 gasket set up I saw online. I'm just wondering if it's worth the effort given the pitting that is present. Thanks

Yes, use the steel plugs to close the heat passage.  For the pits, I would fill them with JB weld to ensure a tight gasket seal.  Luck!

Here's old links to plugging the hot-slot holes, or you can do a search using that term.  I think 7/16 brass plugs work best, but you'll want to verify first.

The pitting should still allow a seal at the neck, but maybe use a little form a gasket first to be sure?

I have used worse. I used silver gasket sealer ( can hardly see it ). I cannot remember the brand but I used a gasket that covered the 2 holes. No problems.

Thanks everyone, that's what I'll do. I did read that post on the hot-slots and the plugs, got some on order as I type this. I'll look for some sealer to fill in the pits, just wasn't sure if that was possible. I'm glad then I can keep to the originality of the car. Thanks
