Should I be worried?

[0rion]

I would run a truck that's been "chipped", cat back, and 3.73's all day long with a stock LS1........for money.

I seriously doubt you have 3.42 gears in an auto. Regardless, you should blister him. Big weight difference.

Yeah I do!! They cam out of a 02 z m6!!

There ya go,,,,,are you worried yet??

Not really, never really was! Just thought Id get yall thoughts!!

Im with you on this FBJ. Have been to the track to many times.. 5.3's can turn around and bite you...

I have much respect for the 5.3s, they are very stout motors!!

[prater_1]

I agree with FBJ here. I do have a question what rear tire size are both running? Does either have a DR on it?

I am running a stock tire and rim and Im not sure what hes running on.

I'm not sure even a long bed 2wd 5.3 would weigh that much.

My 79 1 ton with made of real steel, and a 454/400 turbo, 14 bolt rear, and loaded to the gills with options like A/C, Cruise etc...and those heavy bastard 16.5 inch steel wheels, dual gas tanks, yada yada,,,,and it only weighed 5,250 without me in it.

I don't see a lighter 5.3 engine in a 1/2 ton truck and an 8.5 inch 10 bolt rear, probably aluminum wheels, a long bed 2wd, even coming close to what my old tank of a truck weighs. If it's a short bed it would be even lighter yet.

Our camaro's aren't exactly feather weights either for what used to be considered among the pony car crowd.

They range from 4300lbs-4900lbs depending on size and options of the 2001 1500 series.

Anything happen yet???

[Speed_kills_WS6]

why do you doubt his gear choice? Its been done before

If he's stock he won't. If you're gonna go thru the trouble to change the ratio, why not go 3.73 in an auto????
Just seen where the OP got the gears out of an m6.......

[fouthgen.rocket]

just go on and run him what have you got to lose it will be fun lol

[prater_1]

Anything happen yet???

No not yet but soon! I need new tires first, I noticed a bubble on one of my rear tires!

I didn't do the swap or I would've done something up in that range! I will when I swap in a 12 bolt!

That was actually a wise move. You are better off swapping in a 6 speed 3.42 rear in the auto's. You won't see much (if any) difference in performance between the 3.42's or the 3.73's, not to mention the 7.5's are a waste of time to stick money in.

If you are going to spend $500 + dollars for a gear upgrade you may as well spend your money on a good rear to start with first.

[MrMasterCraft]

I agree with Jones...

Total waste of time, effort, money, waste of it all trying to mess with the 7.5" 10 bolt. It's a 12 bolt/9"/Dana or nothing

Another thing is not every one is a like, maybe he didnt want to go with 3.73's?

Also very cheap to get some used ones out of m6 probably.

[prater_1]

Gentlemen, yall keep missing where I said I didnt do the swap!! I bought the car AFTER the swap!! If I had done it I would have swapped in a moser 12 bolt with 3.73s or better!!

[02sunsetorangeZ]

haha didnt see that. its all good
