What would happen if this were the case?

You need a longer plug for Vortecs (I think the autolite 23 are for stock heads). I am not sure of how they will react, with the plug being recessed.

iirc when i got my truck back from Waller after my (vortec) build he has 23s in it. i think they are shorter than stockers....
not positive tho..

i was incorrect,they were 104s..the red truck was 23s

I have tried many different plugs on my Ty. The Autolite 104 and the 103s (colder) have been the best I have used.

well, I have a used set of 103's that I use in my Impala. But, when you compare them to the 23's the 23's are obviously WAY TOO SHORT. I looked up specs online and the 103 or TR6 is about 50% longer or deeper into the cyl.

I would suspect this could be part of my miss / idle / cutting out problem. We will start with this.
