This question goes out to those that have more experience than I on the 454 engine. I am looking to install an aftermarket direct read with a bulb engine temp gauge.
The factory sending unit is in the block on the drivers side, right above the exaust ports, and with the headers on I cannont seem to get a wrench on it. Is there a fitting elsewhere on the block that would allow me to get to the cooling system and have an accurate read on temps? I am trying to avoid the R&R of the headers as they are well seated, do not leak and I am concerned that I might be opening a can of worms if I begin dissassembly. I am planning on eventually replacing the entire p-30 instrumanet cluster but want to be sure to monitor more that just hot or cold.
I have already replaced the electronic oil pressure gauge, and the volt meter, but I have been stumped by the engine temp gauge.
Any advice would be helpful!
