hi i was hoping someone may remember an article i read  somewhere a long time age concerning the leads on a y block.the rubber insulator blocks at the rear of the engine which hold 4 leads each had a certain order or position for the leads to go. sounds odd but i need to know that order because  i suspect i have a crossfire issue in that area.the article showed the order they go in to avoid  possible crossfire, hope somebody may remember this and let me know,, cheers

It's interesting that there is concern about crossfiring between #6 and #8, but I have not seen any mention of possible crossfiring between #2 and #1.  One follows two in the firing order.  I would think 1 and 2 should be separated in the rubber block as are 6 and 8.

I agree with John, I always separate #1 and #2 also.

Is this a issue anymore with the improvements made in plug wires?

Big window, it might be because of the blocks and there hole sizes. I know 6-7mm wires are probably way better today but guys seem to think that they need top fuel mag 44 amp wires when changing.
My wires have been in 8 years and I think about changing. I’m anal enough to remove the exhaust manifolds to do it and get it right. I also think it’s because most of us went to electronic ignitions.
About 10 year ago I was involved with a custom HD build and we used a Swedish wire we got from Husqvarna for chain saws and put it thru the frame and never had a failure. It was a little over 1/8” in diameter.
A lot of us over think everything.

fantastic! thats what i was trying to find THANK YOU SO MUCH

i thought with modern leads there was no problem ,but i have the only car on the planet that has decided to do  this.(it does not like me sometimes!)

It all depends on wire quality, amount of current produced and trying to fire a lean mixture. There are quality 7MM wire sets out there that will prevent cross-fire.

After researching spark plug wires I found Magnecore to be the best. After almost 10 years they are still as flexible as when new and I'm running an MSD 6A box fired by a Ford Duraspark trigger and Blaster coil with NO PROBLEMS ever.  Everything properly threaded through the blocks and separators and they fit perfectly. I could have bought much cheaper but...................
