David inquiry “Why am ns pointing the rotor towards the #6 plug as soon as it’s #1 top top compression stroke and should it is in firing ??? seems to me that should allude towards #1 plugin cap !!!”Confusing, isn’t it. Let’s watch if we can make some feeling of it.For end 40 years, Chevy followed the standard convention of ‘V’ engine distributor cap which relied ~ above the simple design of the firing stimulate being established by the placement of the sparkplug wires in the appropriate tower the the cap. In most cases, this forced some wires to cross end or under other wires. This created some very ‘messy’ plug wire routing, and feasible ‘cross firing’.

The ‘Vortec’ lid is draft in together a way as to neatly permit for the placement of the spark plug wires to attach as though the shooting order to be such that 4 plugs fire on the right and 4 plugs fired ~ above the left. If you look carefully at the photos, you will notice that castle didn’t readjust the shoot order, castle literally relocated the ar of the spark plug cable tower of #’s 1 and 4, on the V6, and #’s 2 and also 3 top top the V8. This actually creates one ‘across the cap’ firing; not a overcome fire, order.


This is why, as soon as installing the distributor in the V6, you target the rotor reminder at the #6 note on the distributor body. Same goes for installing the V8 distributor, although this isn’t quite as confusing due to the fact that the #8 note is closer to the #1 cap tower, and also doesn’t seem together counter-intuitive.


Two various other things to store in mind. The distributor gear has ‘angled’ teeth. Together such, when you drop in the distributor, revolve the rotor, respond to clockwise about 30 degrees in order because that it to finish up in the ideal place. Also, when doing this, the bottom of the distributor pillar has, what is favor a huge straight-slot driver that has to engage the oil pump driveshaft. It’s not unusual to have to turn the driveshaft in stimulate to expropriate the distributor pillar in the suitable orientation.

So... What do you think? Please leaving me a comment.

Vale:Helpful blog and also diagrams! Is this miscellaneous an median person have the right to do, or would it help to have actually a little of mechanical knowledge?
svfixer:Pretty directly forward task. Anyone could do it, but the most likely hood of the average human being needing to do it is negligible.
Tom:After law the setting to TDC top top compression punch and setup the distributor properly, do you still have do the 2000 rpm procedure ?
Larry Dorr:Well ns from the old school and was totally confused. Currently that ive check out this i fully understand. Great lesson. Say thanks to you
Don Hedrick:Outstanding mine friend. I have actually the 5.7 in my boat. Cane we go one step farther? exactly how to remove and replace electronic came position sensor? Engine will fire and also run for around 5 seconds, or less, and then close up door down.
Runbry:I think this video was informative and, hopefully it is the lacking piece to bring my 350 earlier to life, say thanks to you for the insight
Jake:On the illustration reflecting the mark on the shaft and the one ~ above the gear, if the mark isn’t on the distributor shaft what execute you recommend? ns was an alleged to change one in a 2002 Chevy 4.3 PU this particular day for a lady and noticed the doesn’t have actually a mark! The price is probably going to be obvious and I’ll feel choose a fool but if girlfriend don’t ask inquiries you can’t learn. Many thanks for the assist and taking time to execute this to assist people.
svfixer:I think if you go by the images that show the ‘lead’ place of the rotor before install, that will result in the same.
