What have you guys who have done the swap used to plug the O2 bungs in the headers? I would prefer not to have to use an old O2 sensor, but have been unable to find anything that fits tight. So what are you guys using? By the way, I'm using the Pacesetter LT1 LTs. Thanks in advance.

You can find bung plugs all over the internet for 5-10 dollars. If you hit up the right muffler shop they will give them to you for free.

 

Cool, thanks for the info.

agreed on the muffler shop suggestion. A buddy of mine sells them at his speed shop so if the car doesn't have tailpipes, you can weld these in the header and/or h-pipe for tuning the A/F ratio.

18x1.5mm oil drain plug. Lots of foreign cars use this size, just go to a local parts store and pick one up. Or you can be a cheapskate like me and use a spark plug from an old John Deere "popper" tractor.

 

Used the oil drain plug. It worked like a charm. I was actually able to get home today and we dropped in the motor too. It is actually starting to look like a normal car again. Thanks again guys.

Did you use the same size of oil plug that is used on the fbody? I have an 01 ls1...Thanks

 

I have used spark plugs anti fowl kits and welded the hole shut. The large spark plug is the same thread.
