high temp. low oil pressure, crap gauges

Im getting burned out on my new to me 74 duster. Has a 360, new crate says previous owner. Anyway. I put in a 160 stat cause the 195 stat was stressing me out at stop lights and she will get to the 215~220 range. Now she still gets in the 190~200 range and it still stresses me. i think my main heat spike is coming from low oil pressure at idle I run a synthetic blend 5~30. And I currently have the equux some oriely off brand gauges in. I have these gauges in the past and they did not read right for me then either. Any help would be awesome:banghead:
