I need some help here; I have searched the forum and didn’t or missed what I am looking for. I have rebuilt a 1967 327 and will be dropping it in my 1984 Z28 soon. I want to use the stock gauges etc. The Z with 305 utilizes 2 sending units to the oil pressure gauge. The 327 only has an opening for 1 sending unit, is there an adapter out there that allows me to use both sending units? Possibly someone has crossed this bridge before me and has created a fitting.

Thanks in advance for any help I might receive.

I believe what your talking about is the 2 wire oil pressure switch setup. If I recall, one oil pressure unit is located near the distributor which goes into the block. The other is near the oil filter. The one pressure gauge near the oil filter is also regulated with the fuel pump. If you have no oil pressure, that switch sends a signal to the fuel pump and kills the engine so you don't blow it up. In your case, your going to have to use both oil pressure sending units. Since you only have one pressure gauge on the 327, I would use a brass T to connect to the block were your original sender is and then you can connect the other sending unit as well. As long as oil is going to both sending units, you should be fine.
