keeping eletric fans and elec fuel pump

 

I'd just like to know how he converted a 3.1 to a 350? lol

As said there's lots of information on here about engine swaps.

The gauges are all stand alone and don't need any other electronics to work. They simple connect to their respective senders for oil pressure, water temp, etc.

The only thing needing more work is calibration of the tach, a 6 cylinder tach will read high when connected to an 8 cylinder.
