i agree with 30th but if your engine can spin to 7k 410s might work good

Very true - I wanted to keep going through the traps around 6500 or very close to that (stock bottom end)

Although, on the H/C setups I had before, I would shift at 6800 with the stock bottom end. I had ARP rods bolts and never had any trouble.

I know i posted 3.73's 04 4.10's and you guys all said 4.10s but is there another gear besides those to that i would benefit from more?

Already a lot of opinions in here, but I offer this:

I changed from stock 3.42 to 4.10 about a year ago. My MPG suffered more than I liked. I want from average 25MPG to 20MPG or less. My RPM are higher than I like also. If I had to do it again I would do 3.73. I am nit-picky tho so it may not bother you.

So that is my opinion based on experience. If you want my advice based on plenty of researching on here:
1) If you plan to mod the car with a good size cam... get the 4.10s (or 3.73 if you're nit-picky like me).
2) If you plan to drag race the car at all with sticky tires don't bother changing gears in the stock rear end. Just save for a stronger rear end (12-bolt, 9", etc).

Cheers. :drink:

4.10s all day.

thegerberbaby

ok i think im going with 4.10 for sure, i contacted my local dyno and they said they charge 350 for install, is that reasonable price?

Yeah that's good, my mechanic charged me $250 and he gives me a good deal.

I have 4:11s and absolutely love them. Mine have a bit of whine to them but its not that bad. MPG wise is not bad. Highway I usually average 26-28 ish at 1800 rpm or about 68 mph. I think mine ran total about $940

for about $1500 you mite find a used 12 bolt or 9" bolt in rear end ,it will last alot longer behind a m6.what clutch do you have ?

thegerberbaby

i have 3.08 gears and a stock clutch

honestly idk what i got myself into, i bought the car found out it has 3.08s, a stock clutch, and to much power for it rear end. im barely going to have enough money for a gear change let alone a new clutch and rear end...! what should i do!

Welcome to the world of modding.

thegerberbaby

how long will the rear end last with 4.10's and how much longer will the stock clutch last?

lemons12

You're asking questions that can't be answered. Could be 1 launch, could last for 150.

Expect the rear to break the first time you catch good traction, especially from a dig.
Clutch depends on how you drive it.

Borrowed time on both.

thegerberbaby

Well hopefully since i wont be driving it over the winter i can save up enough money for performance clutch, 12 bolt or 9' and gears...wish i was better educated about cars when i bought this damn thing

arioch

What happened to me, 4:10's where just to much, and unless i was running slicks on the street i could never catch traction, (this was on a bolt on LT1 too)

I like my 3:73's much better.

And about being on borrowed time with a stock clutch, im STILL on my stock clutch with 104,000 miles, and 418rwhp. It still catches just fine but i can never roll from a dig, the tires just blow off the car. I BABY the car everywhere unless im racing it, its all in your driving style.

4.10s and do yourself a favor and buy quality gears.
