Getting ready to assemble my 440 and don't have plug wires for it. It is a 1973 440 with a Mopar electronic dist with a brown cap. Engine also has headers so I think the factory wires wont work. Anyone have any suggestions on wire sets for my engine? Either premade or cut to fit would work. Looking at some engine photos I see many different angle ends. Any help would be great. Thanks

I always thought the less resistance the better (solid wire cores) but people have stated that it ain't as simple as that & also I've seen that Firecore wires get regular rave reviews on here. I'm not convinced. EDIT They ain't cheap tho

We run Taylor Spiro Pros on all our cars.Mine with 2 inch headers have been on at least 14 years.My kids 2 1/8 tubes have been on for 8 years.We have ran them on stock manifolds and headers with no problems.I even had them on my 57.We use the ones for stock BBs and or SBs.Have them on the Harleys that we made from extra coil wires.Rocky

I have run Taylors on two 440's with headers and really like them.

That said, I will probably buy some Firecores next summer.

Firecores work well, and the stock ones are matched well with numbers for easy installment. I love them on my 440.

When I assembled my wedge, I started with Taylor's. They fit great on the engine stand with headers installed. In the car, different story. That pesky power steering box got in the way, among other things. I switched them around as best I could and still burnt one or two wires.

Next was MSD with bend to fit boots (Mancini). They have worked gear. No more burning. Just a little spendy but much better than replacing wires every 1-2k miles(496 low deck with 1 7/8" TTI's in a '70E).

If you burnt the Taylors something was wrong.My kids 62 300 with 2 1/8 tubes and PS hasnt burnt them in 8 years.He does run a boot cover on #7 cyl as the headers are so large.My 65 has no ps and the fit is tight with a 440 and 2 inch tubes.Taylors have been on at least 12 to 14 years.Still pliable and no burns.Rocky

I've had good luck (in the past) with the Summit universal 8mm sets, and a set of spark plug heat boots. My apps weren't Mopar, but a '79 Ranchero and '88 T-Bird, both with 460's and big 2" full-length headers. The "custom fit" sets never seemed to have the lengths dead-on for those apps, and that irked me. Can't beat the price, about $50 total.

I was using MSD Streetfire Wires on my 383-powered, electronic ignition, project- which has some header clearance issues. They are a made in USA, 8mm, black. universal fit set. Cost about $35 at Summit.

Unfortunately I cut one wire a little short, and wanted to redo my coil wire with straight boots/terminals instead of the 90 degree ones that came with my kit anyway.

Autozone was on the way home from work. I usually expect the cheapest of the worst from them, and was expecting to buy a single wire along with boots and terminals for the coil wire.

I ended up buying a complete set of Duralast #1601 cut-to-fit wires (90 degree dizzy & plug boots, straight coil wire boots, plain black rubber, 8mm, 2 year warranty) that are made in USA and look an awful lot like my MSD's. For $15 the set.

I was very pleasantly surprised at both the quality and price. Unless they turn out to have some hidden flaw these should be real popular with the budget-minded rodder.

FWIW Duralast #1600 is the same wire set but with straight plug boots, and both sets come with terminals for both HEI & socket style dizzys.

They've been on a year now, and are still doing fine

MSD makes a nice 8mm BLACK set. Pretty cheap thru Summit. I've used a few sets w/o any issues.

Just dont use the red house wires from AZ.We installed some sets at work.Within a few months all were arcing.We did and I still do use a lot of Autolite wires for stock apps.Rocky

Isn't anyone going to give Firecore a blast? SunroofGTX is Firecore, AFAIK.

R.

Are you guys using 90 degree boots on either end and are you running them under the headers like factory or over the valve cover?

Hello. What manufacture headers will you be using? In using headers, it will be difficult to use most of the stock wire looms.

What about the Firecores are you you not convinced about? I can answer any and all questions. Thank you.

These are Firecore wires with 45 degree angle boots and they fit great. Best fitting plug wires I have used. Ron

The MSD kit allows you to bend the ends to any angle you desire.

i've used a varity of wires over the years MSD, Accel, Jacobs. i even tried a set of solid core which i really liked but was impossible to set timing with my MSD ecu. i still use the coil to dizzy solid wire. the set i use now are also the Taylor Spiro Pros. i alway buy the custom length set and cut them to fit. i also ohm them as i go along. i've also always used 8mm and use boot covers on 2 of them.
