Which way should the rotor be facing?

Which way should the rotor be facing?

For rotors with slots machined in the same direction as the internal cooling vanes, the slots should lean toward the back of the car. For rotors with slots machined in the opposite direction as the internal cooling vanes, the slots should lean toward the front of the car.

Can you put a distributor in backwards?

In this case as has been mentioned all you have to do is remove the distributor and rotate the SHAFT 180 degrees and put it back in the hole. This way the NEXT time the piston comes up will be the compression stroke and thats when you want the spark.

Which way does Mopar small block rotor point at TDC?

The slot in the dist/oil pump drive gear should point to the front left intake bolt when #1 is at TDC.

What happens if you put slotted rotors on backwards?

There is no backwards or forwards with drilled or slotted rotors. Its a preference thing really. If you have the curve going towards the back of the car its overall good braking, if the curves are facing the front of the car people will tell you the pads bite harder thus stopping quicker.

How do you test a distributor rotor?

Switch on ignition, but do not crank the engine over. Hold the coil HT lead near the tip of the rotor, and flick the points open. You will get spark as the points open. If the spark jumps from the HT lead to the rotor, then the rotor is bad and is grounding the spark to the rotor drive shaft.

Can a distributor be 180 out?

If that distributor hasn’t moved since dyno, it’s not 180 out. Wouldn’t run, even poorly at 180 out. Probly cracked a plug installing the engine, landed a wire wrong, or inadvertently rotated the distributor. Time it, and then put your light on all the wires to see if all fire.

Does a distributor only go in one way?

The distributor is a stock Delco unit with Petronix ignition. Of course, the bottom of its shaft is slotted to mate to the oil pump shaft. So this means it can only go in two ways. One way is correct, one would be 180 degrees off.

Are slotted rotors better?

Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.
