73/74 people with big blocks and factory wire looms, What plug wires are you running?

[S&JButler]

Need to buy wires for my Satellite. Not really looking for cut to fit. Trying to (somewhat) use factory style looms. Just looking for some good options. Thanks.

I tried the MSD street fire wires to replace the yellow Accel wires. Noticeable difference immediately. Under $100 (2yrs ago), can't remember if they were cut to fit or not but that's easy anyway

Try the FireCore wires.

To be perfectly honest, I just run Standard Ignition wires. I'll probably get crushed for this but unless you're having misfire problems, high performance wires and coils DO NOT add power. You cannot make more power by super igniting the mixture, it either ignites, or you have misfires. This applies to stock and modified engines, until you start to experience misfires, the ignition is doing it's job.

I’m running the old firecore 250 wires 8 mm. Had to enlarge a bit the looms.

I had to give the measurements for custom build to match the original 73 and lates lenghts based on a NOS Mopar setup I had, because tipically ALL manufacturers offer the pre 72 setup. Dunno if they saved those measurements.

The 440 engine has come in numerous bodies and configurations, so it may be a stretch finding a set that will fit your exect 440 configuration.

These cut-to-fit sets are pretty decent. You usually only cut one end, the distributor end. By mixing around the wires (of varying lengths) in the set, you can place the longer sizes where you need them.

I would give a 7mm set in the your desired color a chance, if you cannot find a more OEM-styled option.

I am going to reach out to Firecore in a couple of days and see if they still have the measurements. If not I’m hoping maybe you still have them? If not I will probably get a cut to fit set and hope they’re long enough.

I should still have the measurements on some email around.

I may even still have the pics of the NOS set being mesured, wires side to side to the measuring tape

I always buy cut to fit style wires with spark plug boots specific to the application, whether stock manifolds, header tube size, straight or angle plug. Routing the wire through as many looms as needed and keeping them away from heat or oil means you only have to do it once. Buy a good crimp tool and once you do it this way you will never buy pre-cut wires again. It adds less than hour to the job, but is so worth it. Summit or Jegs have a pretty good selection of wire sizes and colors, for OE systems I go with 7MM in black.

If you still had these that would be awesome. I spoke to Firecore and after the short conversation we had I’m thinking organization may not be top priority so they may or may not still have them.

 

[Nacho-RT74]

I was pretty sure already posted this info around and found it!

If you scroll down, will find also the pics for the measures I took.

Good thread to read though! This topic about lates spark plug wires setup has been discussed several times in the past

Just as an FYI this came to me S&JButler (Scott). The member you are looking for is:

I just installed a set of summit wires, pre-assembled for big block mopar, SUM-G819. Plenty long enough to go over the intake, and around the back of the head for 7/8, five straight boots, three 90°
Good quality wires, very tight plug boots, 8mm. Very reasonably priced, at least they were when I bought em.
Only thing, the included wire separators were 7mm, and could not be used.
Mine are installed on a 440 with headers, in a 62 savoy.

Firecore was looking for your name so he could look up your order and see the specs. Don’t know if he got in touch with you or not but I forwarded the link you sent me to him.

 

[Nacho-RT74]

Oh, ok… better searching by my email on their sales records [email protected]

I bought my first set maybe 12-15 years ago through one of their sellers (RON, aka firefighter at dodgecharger.com forum) and a second set as a spare straight at their website maybe 8-10 years ago with some measurements corrections (the ones on that thread) but without the 135* boots due the lack of stock they had of those.

Unfortunately I don’t have anymore the second set or the NOS set. They were stolen from the room I had storaged all my cool Mopar parts at a cousin of mine house in Venezuela (MSD 6C module, NOS magnum purple Camshaft and a long etc ) while he was sick just right before die and I’m living already in Spain. Some related probably of his former wife with keys entered and stole lot of stuff from his house, including my stuff.

I used the FireCore 8.8mm factory cut length. Used a Dremel to widen the plastic mounting tabs.
