On a 68 f100 360, I put the pertronix coil , and ignitor in. I have 7.5mm autolite wires already. But 2 are 7.0mm wires... would this matter? do i need to get 2 more 7.5mm. Or do i need to get 8mm wires cus of the flamethrower and ignitor. Also What gap would you all suggest me putting my plugs at? Its at the stock .034 now, i think i remember someone saying i should go with .44 but im not sure. Please give me your imput on this. Thanks

 

Go with 8mm wires and it was me that said you can go to .044 not .44 !

[updated:LAST EDITED ON 22-Mar-02 AT 10:00 PM (EST)]Yea,..... u know thats what i ment. anyway, 7.5 to 8.0 will really make a difference?? because there 30$ and i dont wanna waste my money.

Thanks dennis

 

I know that $30 towards S P wires is more practical than $15-20 on a Flames out the tailpipe.

hahha yea, but i really wanted those flames

 

OK so u are saying that 8 mm will really make a difference??? in what ways

 

Less resistance >especially if they are not radio interference wires.

Question to you:
Does electricity travel easier through a 20 gauge wire or an 8 gauge wire ?

Chris ,Didn't you read those articles I sent you?

They were loaded with technical information.

[updated:LAST EDITED ON 24-Mar-02 AT 00:32 AM (EST)]I belive that the 8mm rating on spark plug wires is refering to the thickness of the insulation not the conductor.A 8 mm conductor is equal to a #1 gauge.This is more like a battery cable than a spark
plug wire.

Thanks for the explanation.

You're correct, I should have been more specific.
I'm sure the wire part of an 8mm wire is larger thus being more efficient as the performance wires are.

I assumed again that Chris would understand what I was stating.

In regards to, size of wire vs resistance

I just put together the accel universal 8mm wires. The wires are fat!! Compared, the 7mm Autozone wires I have are sewing thread. I don't understand why they can't all be at least a descent thickness. For the company to save a few pennies on the wire is rediculous on a $20 product. It's kind of like car stereos with those weak little harness wires.
The wires go for $30 at Pep Boys. I got them on Ebay for '$22.00 to your door'. The guy is great. 'Chimptoast' or something. Btw- ignitor is $59.00 to your door on Ebay too.

Question: I was wondering what the gap differences will do? I see(in operaters manual) that the 390 should be at .032-. Why .044? Will it cause more gas to be used? I measure autolite platinums preset at ~.041. Should I change them?

 

Very simplified explanation: You want the wider gap so that you will have a bigger,longer duration spark to better ignite the fuel. You need a higher voltage to get the spark to arc across the wider gap. High output coils produce higher voltage. Larger spark plug wires (larger diameter = lower resistance =less voltage drop across the wire = higher voltage at the wire tip) provide a higher voltage at the plug. In general, providing a higher voltage at the plug and using a wider gap will improve performance. The thicker/better insulation on the plug wires also helps prevent arcing through the insulation to surrounding objects. Get the good wires. Be happy.

 

That's exactly what was on my mind David, I just couldn't put it all together and write it down.

Thank you sir for your addition to the post.
