    Top dead center for dummies........

    Ok, so tell me the easiest way to find TDC with engine in the car

    Thanks

    Thumb sealing the #1 plug hole, ratchet on crank turning engine over, feel for pressure to rise then stop when you feel the valve open. It's either tdc or 180° off

      TDC is when both valvs are closed and #1 piston is at TDC and the way to find it is line up the timeming marks to TDC. Good luck.

        What they both said. On the exhaust stroke the valve will be open and you won't feel much air trying to push your finger out the sparkplug hole. On the compression stroke with bolt valves closed, all of the air in the cylinder will wanna escape thru the passage blocked by your finger, it's pretty hard to miss or ignore. Then watch the balancer and line up the TDC (zero) mark with the pointer and you should be right on it.

          Ok so...this is how I will go about it on my old Stude.....remove spark plug from #1 cyl, hook up my remote starter switch, place finger over plug hole, keep bumping starter until I feel the pressure wanting to push my finger off the hole, I may have to do this a second time as the pointer on the damper has to line up with the zero degree mark scale tag, just after I feel the pressure on my finger. I am not proud, if I do not have this correct...TELL ME!!! I have NYC skin

            That should work fine.

            If I understand your plan;
            1) Find which is compression stroke
            2) Use mark to dial in exact TDC

                  I would use a ratchet and turn the motor over by hand. It will be a lot safer and there is almost no chance of over-shoot since you can watch the timing mark come around. No idea what the Studebaker crank bolt is but its probably something decently large. A 1/2" ratchet will still do it.

                    Sadly there is like zero room to get a ratchet on the bolt......that is why I have to resort to the remote starter switch.Next to the Packard 352 block that the Golden Hawk carried, the Avanti engine is literally stuffed under the hood.Click image for larger version

                      just make sure you remove the coil wire if you have to do it that way.

                            The blower was a normal thing for the Studebakers actually, may have been optional but certainly not a one-off type of deal like if you see one in say a Mustang.

                            That said, this blower clearly feeds the devil, aka blow-thru carb. Evil them things are, evil! lol
