Ignition Help

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

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

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.
