ok got my 350 in and runnin good finally 2 things though.
1) coolent temp seems to be reading twice the temp that it is supposed to be.
2) oil pressure is pinned and doesnt move.
Are the sensorsat fault in the 350?? they worked fine in the 305 but I am using the 350 ones which is a 77 block thnks

 

ok not just gauge foir the temp wow is it hot I will put a new thermostat in tomorro but the gauge is still messed up thnks

 

you are using the '77 350 sensors for the gauges ??

If so change em out to the ones from the 305 and you problems should be solved.

 

ok thnks thats what I thought. but I wanted to make sure b4 I di the work. big north easter comin so Ill do it this weekend. I have to get up at 5AM. thnks
