Hi All -

Just finished removing stock manifolds and exhaust and installing Dyno Don's headers plus Magnaflow cat and cat-back exhaust. I will be installing Accel shorty spark plugs and new 90 degree boot plug wires which leads to my question.

For those of you that have installed shorty headers, particularly Dyno Don's, what have you found to be the best set of plug wires for clearing the header tubes but also of a good length so as to not have wires that come up too short or with too much excess slack? Accel, Taylor, etc.? Specific series or model number would be helpful. As always, greatly appreciate any information you can share!

Thanks,
Pete

 

Probably not what you're looking for but I just bought two sets of stock wires, used the ones that got me down the back and under the exhaust and with the angled ends. Actually used 6 of the rest of the wires on my V6 truck engine. No more expensive than the high dollar performance wires to go this way.

 

Buy a DIY spark plug wire kit. You can buy them in straight, 45* and 90* boots and the wires are cut to length. You can route them any way you desire. I don't know why anybody spends their money on anything else.

 

I'm with Tibo, get a DIY kit. I've used MSD 8.8 Superconductor wires in the past, but there are plenty of options.

....as for clearance...I can speak to Don's headers, but I know my SLPs are TIGHT with my RHS heads. Went with some short Autolites. By dumb luck I happened to have installed Remflex gaskets, which I'd day gave me an extra 1/32 to 1/16 of clearance. Doesn't sound like much, but it made the difference for me. ....my SLPs with stock heads had room for days. Ran stock length AC Delco RTS45 plugs. Again, don't know about Dyno Don's set up.

 

Thanks guys for the replies. Great advice!

 

I have Don's headers on my 91. I also used MSD. After experimenting with the different lengths in the set I was very happy with how they turned out. No clearance problems. Of course I have no idea what the heads are on my motor, lol! But they have perimeter valve covers, so I used a summit wire loom kit. I can take a pic later if you want.

 

Pics would be great. Thanks.

I always chose the BW Nascar select but they have been disco (like everything else) they were reasonably priced and the right length.

So, now the best option would be the MSD red or GM high performance.
Both are pricey. That said, try to find the ones with the small 90 degree boots. (more clearance)


These have the least resistance 1k to 2k per wire, stock are 8k to 10k.

Here is a nice set HEI dizzy end but will work ok:

I've always used Taylor "Spiro-Pro", like these. https://www.summitracing.com/parts/tay-73051/overview/ They have em in about a dozen colors and with various connectors both for the plugs and the dist ends. They're somewhat less than 500 ohms/ft if memory serves, can't recall exactly.

I've also always had good luck with running them in the stock location, underneath everything, with 90° boots. I prefer that when possible rather than having them draped on top of everything else. Might take 2 sets to get enough long ones though, it depends on how you'd end up having to route them.

 

Great info guys. Thanks

 

Been busy this week, but here's my setup...
