Hello everybody I came across this site searching online for some Olds forums. I've been working on cars my whole life, I'm 24 and have owned at least 30 cars lol. I recently purchaced an 86 Cutlass Supreme brougham has the 307 with 154,*** miles. I'm the second owner and have all the paperwork throughout its life, car is still in pretty good shape for the year 98% rust free body, original paint and pretty much all stock. I've owned alot of older chevys but no Olds, so there are a few issues with the car that need attention. Looking to grow with the site, learn some things and meet new people. Thanks alot.

Don' attempt to modify the motor. It is nearly impossible. It has the 7A swirlport heads. You cannot find a cam to match an aftermarket manifold. If you do, you will still need to employ "emission control". Not saying you are going to modify, "Just don't even think about it".
The 307 is a very good motor, but they've choked it with emission control. It has a positive backpressure EGR, so do not think of using dual exhausts. A few tips. Welcome.

Thanks guys. Heres a pic. Im putting the stock wire hub caps on it today just havent got around to it. I don't plan on doing anything to the motor except tune up and maybe a few small things. So far I've only changed the air filter and detailed her inside and out. One of the first things I wanted to do was install duals. Not true duals but one in/two out muffler. Is there anything I can do with the emissions to get duals or will I lose all my back pressure/ run like crap? One thing that worries me about it is I have an aftermarket oil pressure gauge and coolant gauge, and at idle it says I'm only at 5-7 psi. Seems kind of low to me but there is also a small oil leak thats drips off the oil filter I don't know if that would affect it or maybe a clogged oil filter? There are no ticks or knocks runs smooth and quiet. It has 10w-30 oil in it that looks like it needs changed so ill be doing that this weekend. Any preferences on oil weight and brand? Another thing is after driving for awhile it seems to get a little hot around 215 degrees so I have to kick the heat on, I'm guessing because its missing the fan shroud? Theres no coolant leaks or coolant in the oil. If you guys have any suggestions on where to start I would greatly appreciate it. Thanks in advance.

Anyone? Should I post my questions in a different topic or something?

86Olds307,
I'd try to find and install a fan shroud and then check to see where the oil is leaking on the oil filter. Is it leaking at the filter gasket (maybe it was tightened too tight) or possibly at the valve cover gasket. Just some ideas I'd check.
Oh, welcome to the site.

Don't try two into one duals. The backpressure is a significant issue, which will increase heat. It does not matter whether 2 into 1, or running straight pipes. 10w-30 is the oil Penzoil or Extra Milage Valvoline, Castrol is good, and Quaker State, which many people overlook. Don't change the weight. It was formulated for that motor. Unless you live in an extreme climate: hot or cold, use 10w-30. It appears you live in Ohio, so use the 10w-30. While you are at it, change the transmission fluid and filter. Perform a compression test to see how each cylinder is performing. It takes about thirty minutes. Do it yourself. All Oldsmobile's "run hot". I've owned many. You refer to a 'fan shroud', I believe that you are referring to the "clutch fan". Without this, your motor will run hot. Change the thermostat, and make sure it is the correct temperature. I believe that it is 195°. * Check the "air tubes" for leaks: part of emission cotrol; bolt on to the manifold.
