Oil pressure is really low

Pressure rising as you increase rpm is normal. 15# at idle is acceptable. Spend $20 on a cheap aftermarket temp gauge, your gauge might be reading way off, especially if it is the original stock. Mine started running hot and that is what I found out, it was the gauge. In you case if its spewing but only reading 180 something is wrong. What temp t stat are you running, 185 is standard? What pressure cap, 5 # is all you need. If someone put on a higher pressure cap it can cause problems. You might want to get an inexpensive probe type thermostat, run it up to what you think is hot, pull the cap a see what the temperature is. Are you using just water or coolant mix? Does it have a shroud, if the fan is not close to the radiator, might not be pulling enough air thru it.

I just put a new Thermostat and Temp sending unit last year. Its spewing vapor every where. Last month I bought a Standard 7lb radiator cap. Radiator seems fine, the fluid is bright green. I think the Thermostat was like a 185 degree one, the truck gets hot as hell, but the heater doesn't work so that tells me that the heater core isn't good.. Also, my truck just now started spitting and sputtering out of no where. It ran fine last week, and I just put fresh gas in it. All new ignition parts, I did notice that the plugs had carbon on them. It pops out the carb a little while driving, and pops through exhaust, just now started doing this again

Bipass the heater core and check the hoses to it for blockage, that could be your part of your over heating issue. Sooty plugs is carb jetting issue, choke is staying partially shut making the mixture too rich or timing (fuel not getting completely burned). Yes I know you got a new carb, but that does not mean it was tuned for your engine. Backfiring thru carb AND exhaust means your timing is jumping from advance (carb) to retarded (exhaust). This will also affect the engine temp., retarded timing causes temperature to got up.

I haven't changed the plugs since putting the new carb on. I just wonder if I put a new set of plugs in, if it'll fix the problem. I am missing a piece of the carb that goes to open and shut the choke any way. I have looked around for the piece on the internet and have had no luck.. What could be causing the spitting and sputtering.
