wtm, interesting about the no thermostat. i'll pop one in there and let you know. as far as the guages are concerned i am using smiths which came with the spf. the fast engine management system reports engine temp as well and the two are within a couple of degrees. the fuel pressure is spot on. i had to disconnect the
oil pressure gauge as it is mechanical and came loose from the sender. it started a small fire while on the dyno. i have since ordered an electronic gauge set by autometer.
