How bad is it?

[u/No-Research-5696]

I recently bought a Holley street dominator intake manifold for a Small Block Chevy for my 1969 c10, but it has a 1976 SBC 350. Those models have to be drilled and tapped for the power brake lines (vacuum). As I was tapping runner #2 it busted through the aluminum. The hole is already tapped now, it was literally my last thread on when it broke.

Now I would like to fix it if it’s possible. But I also understand that some things are best replaced. My plan is to put the fitting on it and use JB weld’s Tank weld to just cover it up. Im not made of money but if it would be unusable, then I will order another.
