Re: Going Howell TBI, but the \'82 needs a bung-where?

My '82 had a threaded hole in the manifold. It is just above the flange for the front exhaust pipe section. There was a large cap rusted in there. It came out with some PB blaster and a large breaker bar. The threads were the same as the Howell O2 sensor. If necessary, I think you can actually weld the bung into the top section of exhaust tubing just before the manifold. That way you aren't drilling/welding cast iron.
