    Question Delco window type 8 cylinder distributor

    Can any one please display a picture or accurate diagram of a Delco window type distributor for a 61 259 with #1 hole clearly labelled? I know the firing order. Every diagram I have found shows number one in the middle at the front. But my distributor has a hole on either side of the middle. Which one is #1?

    I found this image for a Chevy. Is the Studebaker the same?Chevrolet-Impala-5.7-1972-3.JPG

    Odd cylinders are on the left and even on the right - numbered as above - putting #1 left front up next the battery. Good luck.

    Mine falls in the middle like the diagrams that you found. If the distributor is dropped in one tooth off it could be to the right or lrft of middle. The middle is just the normal spot. Number one could be any location on the cap, depending on where it was dropped into the block, with number one piston on firing position.

    As you look at the engine from the front, the distributor is at the back and the odd cylinders would be on your right and even on the left wouldn't they be?

    I guess I'll be pulling plug number 1 and getting that piston to TDC and noting where the rotor points.

    Left and right are as viewed from the driver's seat.

    When you are close to TDC, look to see where the IGN is on the crank - when it lines up with the timing point, the rotor should be pointing directly at the #1 plug. Good luck.

    Thanks. This is all because I naively thought there would only be one possible position for the #1 wire and that it would be in the owner's manual or readily available on some spec sheet. The old cap had all the wires positioned correctly but I pulled them out without making note of their positions.

    Look at it as a learning experience. The next thing you disassemble, you will pay closer attention.

    The best way is to place the new cap next to the old cap and replace one plug wire at a time.

    Always great to ask questions and get the information.

    My first Studebaker was in college with a 62 V8. I thought I would be smart and do a tune up on my own. When I tried to start it, it kicked, back fired and did nothing close to starting. My step-father came out in the drive way to see what was wrong. When I told him that I had put the spark plug wires on in order - 1-4 down the left bank, and 5-8 down the right, he almost swallowed his cigar because he was laughing so hard...

    Lots of extremely knowledgeable people (minus yours truly) here to answer questions, so ask freely. Good luck.

    Please remember that Stude distributors turn counter clockwise.

    Instead of left and right we should use passenger side and driver side, like starboard and port. Though please note: this was not my issue.

    NO, Left and Right is better. We have plenty of people here that drive Studebakers with the steering wheel on the Right. So Driver's and Passenger's side is not a good reference nomenclature.

    As usual it is best if you find where TDC for #1 cyl is, then look where the rotor is pointing to on the cap. The Vac advance should almost be perpendicular to the crankshaft and pointing to the right side.

    This illustration shows #1, one clockwise from the forward clip, or right of center..

    1-4 and 5-8 would be correct for a 50's Ford engine like the 272, 292, 312..

    Problem solved. I used the timing marks to get #1 to TDC. My #1 wire is aligned on the left side just ahead the adjustment window. Runs like a top. I used a meter to get the dwell right on. Thanks to everyone for your inputs.

    Glad that you got it figured out. Now that you've done it, it will be easy next time!
