So just going off of that I'd assume it to be a better roll racing car but you might be right if it has 3.42s.

That's why I want to race and find out lol

I may be wrong. I was thinking the non-1LE SS was still using the old 3.42's that GM often uses. I thought more of a "what diff your car has" thing, and was thinking the only cars with the 3.73's was the SS 1LE and M6 ZL1, but I'm probably wrong on that.

BTW I would agree that in that case the LT1 given traction, same transmissions and equal drivers should be slight quicker than the SS cars based on its weight advantage.

My 1SS 6MT has factory 3.73 gears.

Easy mistake to make given how much that happens with gm cars and different rear end options, but all 6th gen m6's have 3.73s.

I tried really hard, but I could not get any gear companies to make us some 4.10s. No results unless some did it since early last year. First gear is too tall! But great for a 0-60 number.

I have a love hate relationship with out gearing, sometimes I love it and sometimes I wish it was a little shorter.

I think the fix for me will either be more power to run them out a little quicker or it would have been nice to have had an ever slightly more aggressive rear end. I guess more power is the only option as you already mentioned there are no rear end options

Wow! Noone makes a 4.10 for these cars?

I'd assume a S550 Mustang can use most any popular rear gear as I believe its rear diff is based off the common 8.8" rearend?

I'm going to ask some questions to try to get a better understanding of these cars.

-Isn't the rearend in the LT1/non-1LE SS different than the eLSD rearend in the SS 1LE/ZL1? I don't mean is the diff different, but I thought the common rearend used like a 8.6" gear set, and the eLSD used like a 9.9" gear set? Again this may be wrong, and is why I'm asking.

-If the rearend is a 8.6" is it not based on the old 8.6" 10 bolt that many Fbody owners used to say the Fcars should of gotten instead of the smaller 7.5"/7.625" 10 bolts that they ended up with?

-Aren't the rearends in these cars based off the same rearends that the GEN5 cars used? Almost surprised a 4.10 wasn't available for them seeing as they were very popular cars and I believe they came with a 3.42 in the M6 SS cars other than the 1LE? I'm pretty sure the GEN5 SS 1LE came with a 3.90 or 3.91 rear gear? Going from a 3.73 to a 3.90 wouldn't be a huge difference though, so if their gears work in our cars it wouldn't likely be worth the gear change I wouldn't think?

I'm not sure on everything else but yes in th 5th gen I believe the 1le's had a different rear end ratio. You're also right on 6th gen 1le's and zl1's having a 9.9.

I wouldn't think the 6th gens are compatible with anything else or the fbody rear ends since it seems noone I swapping rear ends on these cars except from other 6th gens (v6s, auto - m6, ect)

I think the Gen 5 ZL1 difs will work as Chevy suggests them for drag cars, but they are super heavy and also 3.73s.

The gen5 1le diff will not live long with more power and a sticky surface. Ask me how I know. :(

Here is mine with dragpack and longtubes only stock tune full weight I’m very impressed with this car

That is impressive. You're trapping nearly as fast with your Camaro with only LT's as your FBO Scat Pack that you run low 11's in. How accurate is the timer in these cars?

I have no clue I use the dragy gps device I’ve used the device at the track and it’s splitting hairs when it comes to times

Not sure if this is old news, but Ford has a CAI, throttle body and tune kit that gives 479hp and 438tq on the Mustang GT. For $1295 seems like a nice upgrade with factory warranty. Notably +42lb/ft at 2000 rpm. Wish Chevy would offer the same deal for the LT1. A base Mustang GT is around $35k + $1295 for the performance package seems like good bang for the buck with a warranty.

I'm around a lot of mustang guys and I've never heard this mentioned. Wonder if it actually delivers in real life.
