And LPE, that explains how your car's underside looks so clean. Interesting mounting solution-but it's probably for just one guy.

I have an LS6 that I bought for a swap, and now that I finally got to inspect the engine, although most of it is in good condition, a fire damaged the coils to the point that I dont wanna risk it and want to replace all of them. I see that a lot of ppl replace them w truck coils. Is it also recommended in my situation? Would i still get to use my new set of granatelli spark wires and tr55ix plugs?
Would I reuse the bracket or use a truck bracket?
If I bought an used set with the sensors, would they be plug and play with my LS6 wire harness?



Thanks!

The truck coils require the correct truck brackets and harnesses as listed in post number one of this thread.

You should get a tune to take advantage of the truck coil's abilities.

If the valve covers have no bracket mounting bosses, what would you mount the brackets to?

Smoothie valve covers (without bracket mounting bosses) are for those who want to re-locate their coils.

Holley makes valve covers that do not require brackets for Ls series motors but they only except the 72mm bolt spacing coils.

Google Holley 241-91 you should find them pretty easy.

Yes BUT this thread is specifically about upgrading to the more powerful round truck coils with the heat sinks.

Got it. Being new to the LS series motor I was curious if they had a similar bolt pattern to the LS2 style coils. After seeing the coils I see thats not the case. Thanks anyways!

Check this s%$# out! I found these billet brackets on a popular online auction site. They group the truck coils a little closer and lower them down a bit on the valve cover. I had to use an MSD truck wire on the number 8 cylinder, but otherwise they fit without contacting the hvac box, the wiring harness on the passenger side or the fuel rail on the driver's side! I know, it's just a stock ls1 fuel rail... but I hate modifying my stock parts when there's a chance I could sell them down the road. And this looks better

I sent you a PM. Turns out the guy I bought them from on eBay is an LS1Techer and he fabbed these brackets to clean up his engine bay on a Fox swap... this was the first set he's sold and I believe he intends to sell more now. Funny fact, he had no idea he was solving a problem!

Yes, the coils share a screw on the inner three points.

Also, he pointed out that the brackets ARE removable with the coils on, you just use a ball tip Allen wrench. I didn't think of that, cool!

Just search on ebay for "ls1 585 coil bracket" and you'll find the seller has more than ten of them for $65.00 plus $7.00 flat rate shipping. Here's some nice big clean pictures of it:

Nice as they are, I'm not sure if they're for everybody. Anyone using it would need a custom wire set as the coils for cylinders 2 & 7 are further from the plugs than the others.

I'd say these brackets are not for me.

If the maker made this nice bracket with the same coil placement & spacing as stock (but still further towards the plug side getting away from the fuel rail) then I'd be interested.

The coils are 10457730 (GM part number) (AC Delco part number D585), eight coils needed.

The coil mounting brackets are 10457736 (GM part number), two brackets needed.

The coil harnesses are 12601824 (GM part number) two harnesses needed
are these coils still the same current ones being used now or was there any changes since this thread was made?

Do you mean the plastic fuel rail covers? I wondered the same thing. If you swap to the truck bracket there won't be the studs the clips snap on to. Anyone using the fuel rail covers that can speak from experience?
