  • Firing order question Chebby 350

    Ok, so I finally have time to change out the cap, rotor, & put in the 6AL.
    As I'm double checking the firing order, I notice that the way it's currently wired, NO way comes close to everything I can find on the firing order.

    No 1 wire is at 11:30-12:30 o' clock position closest to the firewall VS at the 5:30-6:30 position it should be. Also, the firing order doesn't follow the same pattern 18654372??

    It goad different. When I tried to wire it as standard, it wouldn't even come close to firing.

    It has an HEI dis on it. Stock 350 as far as I know.
    I did check and make sure the motor was at TDC when starting. The rotor pointed backwards toward the firewall. Could it have been put on backwards from previous owner?
    Still trying to figure this thing out. If any one on the N FT Worth side cares to take a look, I will be more than happy to let ya.

    Any thoughts or suggestions?

    Could have possibly been 180 degrees out and rather than restab distributor they hiatus rearranged wires. Firing order is 18436572 on Chevy and Chrysler (clockwise rotation), bring number 1 up to tdc on compressionn and check where rotor points, rewire and try to fire, if still no start, start #1 straight across from current spot.

      Honestly it doesn't matter where the cap and rotor point as long as it's all in time.
      Just because the balancer was at TDC doesn't mean it's right, it needs to be at TDC on the compresion stroke.
      Easiest way is to pull #1 plug stiick your finger in the whole, turn the motor slowly until the pressure blows past your finger and then make sure it's on TDC.
      Make sure your rotor is lined up with witht he # 1 plug wire and it should be close enough to either start or try to start. Then it's just a matter of getting it to start and throwing a timming light on it.
      I would pull all the wires and put them back on 1 at a time to make sure your order is right

            It doesn't run or even try to when the wires are run in that order.

            I made sure the motor was at TDC by pulling #1 plug and checking for compression stroke so I know that's right.

            It's wierd, it runs perfectly fine the way it is now, but it isn't on the firing order it should be??

            I will write down the order tomorrow when there's light and post it.
            I tried several positions on the factory order and nothing worked. Put it back the way it was and it runs fine. Luckily I marked the cap on where it was to be able to put it back.

                Odd cylinders down drivers side, 1,3,5,6 even down passenger 2,4,6,8, not like Ford

                  and clockwise distributor rotation if that wasnt mentioned

                    Dont ever worry about where the rotor points at TDC. You can make it point anywhere you want when you stab the distributor. Just remove power from the coil so it wont fire, pull the #1 plug and have someone bump it over using the key while you have you finger covering the spark plug hole. When compression pushes air out the hole then your on #1 compression stroke. Where ever the rotor is pointing, that is #1. What ever you do, do not loosen the distributor clamp, the car ran fine before you decided to yank wires off so its already timed. Your just trying to figure out which wire on the cap is #1.


                    This will show you which cylinders are #1,2,3 etc as well as the distributor direction and firing order. http://www.offroaders.com/tech/V8-en...ring-order.htm

                      Whoa whoa whoa...

                      It doesn't matter where the rotor is pointing when the #1 piston is at TDC.

                      What matters is that the #1 plug wire is connected to the terminal on the cap that the rotor is pointing to at that time.

                      If that doesn't make sense, then stop what you're doing and get someone to take a look at it.

                        Ok, so here is how it is wired to run:
                        1-8-2-3-6-7-5-4

                        Why the hell would 2 & 4 be switched? This is the way I picked up the truck am the way it has been driving for the past month.

                        Whiskey Tango Foxtrot????!!!!!!

                        Has this jacked up anything?
                        Should I switch 2 & 4 back??

                        Inquiring minds want to know!
