is that on drag radials?
That is on street tires.

I beat the living :q:q:q:q out of mine... I ran straight pipes on that car as well... but throw a rod through the side of the block right around 97,000 miles
you should get a set of drag radials... and launch it at 3500 RPM
Getting 4.10 gears in these cars will not hurt drivability in the slightest. Before Jason and I did his 4.10's for his LS he was toying with the idea of only going with 3.73's just to play it safe for the reasons you just stated. After I convinced him with allot of talking and a rear end gear vs few trans gear vs engine rpm table he decided to go with the 4.10's. After we installed them he loved the results obviously. After he had gotten used to it a little bit he said that he could have probably went with a 4.56 rear gear and been ok, even for highway cruising speeds. Pretty much think of a 4.10 gear in the LS equating to a 3.73 gear in an older Mustang. The biggest difference is that these 3.9 engines are just so smooth running. 4.10's are nothing when it comes to drivability and manners for these cars.
The shift time in 4th gear will be minimal at worst. Shift time becomes pretty critical in a manual car where the driver has to row the gears. Not nearly as much critical in an auto. Not saying it doesn't factor in but it doesn't weight near as heavily as shift time in a manual.
Level Ten has been offering builds for these transmissions for years now. As of two years ago they were able to hold about twice as much power than any LS has made to date on nitrous, turbo, or supercharger boost. It will hold up to ANYTHING anyone will almost ever throw at it in an LS. Unless someone gets REAL motivated and brings 25 grand to the table then I don't see anyone surpassing a power level that would be able to break anything in one of those Level Ten built 5R55S, N, W transmissions.
heres my input...
A 05 mustang GT runs high 13's because its got 300hp and 320lb ft with a LSD, and i beleive a solid rear axel instead of IRS. these cars obviously dont. thats a factor lol.
I also dont see what a stall convertor would do for this car. Youd have to run slicks for sure. In just my experience to the track launching at a low RPM is the way to go. too high and youll just spin on street tires. The only reason id ever consider messing with the stall in these cars is if i had aftermarket camshafts.
4.10's and slicks would also be a reason that i MIGHT mess with it. But as the car sits traction is already and issue. the highest it can launch is probably perfect for slicks.
Youd also look pretty gay with slicks on a Ls and only running 14's, especially after you warm them up. Nitrous setups (if everything holds) i think could possible see high 12's with the added traction of slicks and a 125shot
theres better investments out there for the cost of a convertor, and there proven too. Nitrous would be one of them.
I myself have always wondered if anyone has ported the TB intake and heads yet.

all i can say is the launch in these cars SUCK! I'm use to 4000RPM launches in my mach 1 on street tires and a 3.55 rear gear... And i know the 4:10's wont be an issue... just from the fact of the gear calculate i used... and have been experimenting with... I know a mustang gt has 300hp and 320 torque... my LS is rated at 280hp and 286 torque.... not that big of a difference...
Now when your talking Gen 1 that is a different story... you need to remember the Gen 2 has more power... I see this being a high 12 second car on gears, stall and the bottle no problem... Now dont tell me i wont hook on a IRS when 03 04 cobra mustangs are in the 9's on a IRS! and they have no wait over the wheels... It can BE done.. And i just might have to be the person to do it...
You say 4:10s will do nothing but spin... I don't think you have delt with cars that have had much power.. because getting 350 or 370 HP and trq to the ground is easily done.... Now if i was making 500HP that would be a different story...
I know its going to need slicks thats a given... not arguing that...
I'm arguing this comment of you will look gay running 14's with slicks... 12's is pretty damn quick... maybe his first gen will stay in the 14's but once i'm done with this thing is will be in the 12s on the bottle gears and stall, daily driven!
I mean :q:q:q:q you can find lincoln mark viii third members on ebay all day long and on this forum with 4:10's already installed... then a couple hundred bucks to ills for the bracket for install and another couple hundred for a set of Gen 1 axles... shortin driveline and at the same time through in stall.... set of drag radials and i bet this car would pull a mid 13.. thats respectable to run slicks in my eye's
I have many years of dragracing mild to wild vehicles at various dragstrips around the country that says otherwise. Dropping the pressure will help some but a small burnout will too, even on streets.
i think a stall and the bottle would be the best mod for the buck in my eye's
bottle, then fuel pump and more bottle
although an xcal is desireable with any power adder for fine tuning and data logging.
Why do Mark hook wit IRS but LS' are spin machines?
I see... It is nice having an easy diff to get parts for... 8.8"s of win!
Bottle....spin your butt off....fuel pump....more bottle and spin your butt off even more... Pretty serious traction issues that will murder ET's once you are around 100shot or above; probably even on a Gen1 too. When I was running the nitrous on my Gen2 LS there was no way in heck that I was going to bother pushing anymore horsepower with it until I got traction with the power I already had. Once the nitrous hit that car spun like crazy even with the progressive controller. If I had stayed with nitrous an LSD would have been my very next mod. Then maybe DR's after that.
Some of the more basic mods are assumed to be done at that point. Though it is not necessary, CAI, tune, and maybe exhaust will probably already be done before digging in deeper with nitrous, stalls, or LSD rear ends.
