SOURCE: Where can I find a spark plug wiring diagram for 1997 3.1l engine

Normally the firing order will be stamped on the top of the intake manifold also the number one plug will be the front one on the drivers side of the car. On the top of the distributor cap you should see a number one that is where the number one plug wire goes follow the firing order on the manifold and go clock wise on the distributor cap

SOURCE: i need to reset the timing on my 93 oldsmobile

You must have an ignition distributor to be able to reset or change the engine timing. If you do have a coil pack then the engine timing is completely controlled by the computer and there is no timing adjustment.

Can a v6 ford engine fit a olds cutlass supreme


No. Thankfully, such an abomination has never been ...well, no doubt some idiot somewhere has actually done it. The only similarity between GM and Ford cars is concept and powertrain layout. Little if anything is compatible or interchangeable between them.
Ditch the supreme and find a ford car needing the exact same engine as yours.

Chevy S-10 upgrade


You need a donor vehicle, or a good junk yard. You will need an engine from a 95 up V6. You will need the complete engine, wiring harness, ECU, and harness. You will need the radiator and motor mounts, You should go ahead with the transmission swap also, being the 4 cyl.trans will be a bit weak for the v6. Look for the 3.4 v6 if you can find one. This swap from a Camaro is a good choice. The engines from the a Comaro are a bit beefier. What ever car you get your engine from, be sure to get as much wiring and all electronics as you can. Now if you do not have any Emissions problems where you live you will not need the ECU's or the wiring to go with them. You can run a carb engine and the swap will be a lot easier. You can get a manifold from Summit and a carb. and have plenty of power then. Good swapping.
