Re: 427 smog hole threads
Terry, Joe, John - Those are some clever ideas and I'm no longer thinking about the old AIR 'extensions' I tossed, I now have alternate ways to 'plug and seal' the Dorman Bigblock exhaust manifolds I'll be ordering. An earlier reply mentioned Grainger as being a source for the 1/4"-18 National Straight Pipe Thread taps, I assume they'd also be a source for the actual plugs?Thanks, Mike T.
