Default How to plug Smog (AIR) ports in exhaust manifolds

We are putting a '95 Camaro LT1 into a '86 Monte Carlo SS. While I was going to retain the engine in factory condition for the initial swap, I have found moving the A/C compressor from the passingers' side to the drivers's side of the engine with a Bowers Rod Shop relocation bracket kit to be a better alternative to notching the frame and fabbing a right engine mount. However, the Bowers bracket sits in the area of the factory AIR pump, so we have decided to delete the pump and lines. But, I am having no luck finding a set of threaded plugs to plug up the holes left in the manifolds. Does anyone have any experience in this area? Someone told me to look around bigger auto parts stores for a large metric oil drain plug for a ricer, but so far I haven't found a large enough plug......

I would plug them by installing headers that didn't have AIR/EGR fittings.

You can use headers for a regular gen 1 sbc on the LT1 just use the header gaskets that come with the headers or upgrade to copper or whatever you like . But if you want to use the manifolds I think they are pipe thread so maybe a trip to the hardwarestore is the answer.

go to a menards or somewhere that has threaded rod, use a pitch gauge etc to get the right diameter and pitch or just bring in the little section of pipe with the nut on it to the store. then cut the length of rod flush with the hole and use some thead sealer or gasket sealer in the threads just to make sure its sealed.

or take the easier route go by napa and ask for a brake fitting thats 3/4 i think ask for however many you need and install em, i cant remember if its 3/4 or 7/8 but it is standard. or take in the fitting from the line that plugs into the manifold and ask for a fitting thats plugged, thats like the fitting from the manifold

Hardline 42 got it. It is a M22X1.5 metric, and the easy fix is to go to your local auto parts store and get 2 replacement oil drain plugs for a '94 to '01 3/4 or 1 ton Dodge Truck with the Cummins Diesel engine.

Thanks everyone!

With them capped and the egr tubes unplugged will you still pass the infamous smog test, for those of us in sniffer counties?
