Preparing for LT's
Preparing for LT's I plan on getting some LT's and ORY pipe before the end of the year. I had bought some o"reillys auto parts plug wires, but decided to take them back, bad fitment, just didn't care for them or the price. My question is, are the MSD wires what I should be buying since I am getting the LT's. Here is the link for the ones I am looking at. http://www.summitracing.com/parts/MSD-32819/
Also these say they fit LS1 also, and a bunch of other LS series motors, what is the difference between these and the ones above. Other than color, and the obvious. http://www.summitracing.com/parts/MSD-32813/

Yeah I just changed the plugs, but hell I might as well change them again, when everything is apart. Anybody know the difference between the 2 in the links I provided? I would prefer the red ones simply for the color. lol
I'd imagine the only difference is the color...all the other specs are called out as the same. I don't think there's really any difference between any plug wires out there for LS1 cars...I've heard good and bad things about all of them. I'm running a set of Comp Cams wires and haven't had any issues with them.
You may want to look at some high-temp spark plug boot protectors, too.

Yeah I am gonna buy some of the red MSD's with the plugs from a member on here. I just gotta call him and do it. Where would I get a boot protector for the MSD's? What header bolts should I buy and is there anything else I need? How big of a difference do the LT's make on the butt dyno?

Pick up a set of GM MLS exhaust gaskets, and it probably wouldn't hurt to buy some stock exhaust bolts, depending on the brand of headers you're going with.

clean the bolts and threads in the heads and re-use them with the gaskets, you don't need to use boot protectors i've never had an issue with them gettin to hot and i've never heard of anyone having that issue. depending on the tuner and the dyno you might see at most 15-20rwhp depending on muffler also, a cut-put will get you the most but when you close it you'll lose that power until you open it again

The spark plug boots would be good insurance. I will probably buy some new header bolts and maybe some new gaskets. Car has 150,000 miles on it so stuff has seen better days. I want to do everything correct the first time so I don't have any problems later, try to keep the "**** happens" factor down. Thats why I am gonna start buying the stuff over a small period of time. Doesn't look as expensive to my wife that way. lol
From what I read my exhaust manifolds are worse than the 00-02, and my cats are prolly sucking some power away as well. I have a borla catback and a manual cutout, so I should see some gains on the SOTP meter. I would guess its gonna be very loud.
Can you use the OEM boot protectors with the MSD's?

"Power" is relative, and at what RPMs -- people love to talk so vaguely about power and the cutout open -- it's likely just upper RPMS with a cutout open, loosing power at lower RPMS...
I was thinking about buying a chris ram air kit, or something to that nature, but the car IMO is plenty fast once going 50mph or so. I want to concentrate on power at all levels. Not something that works better the faster I go. I actually want to do a cheatr cam over the LT's, but I know thats the wrong order for modding.
if your saying what i said is wrong you might want to go check with your local dyno shop . . . i'm not talkin about usable power throughout the band, i'm talkin about peak power will be more through a cut-out VS all the way through a choked catback. if thats not what your sayin then my apologies
I feel like with my cutout open I get a lil more up top and lose some down low. So I agree with you there. With a M6 around town you can tell the difference. I would probably use mine more if I didn't have to get under the car and mess with it. Not for the power, but for the extra loud sound that comes with it.

Having power down low is nice, but I don't race at 2000rpms.
Yes, I am agreeing you will make more power cutout open in upper RPMs, and loose power in lower RPMs with the cutout also open...

i ran the standard ls1 MSD wires and still used the original aluminum plug sleeves..no melting at all here.
i had a cut out on my stock exhaust picked up 2 tenths with it in the 1/4. i then bought a quality cat back and got rid of the cutout...picked a lil over 3 tenths. after that i was not a firm believer in the cut out as a valid performance option.

Way too many variables at the track to do an honest comparison. Back to back dyno runs is really the only way, which have been done numerous times.
Heck you could see a gain from just taking a big **** in the morning, as opposed to not taking one at all.
