Yea, Corvette's have highway gears pretty much. That's how alot of people beat them on the street and then get a big head out of it..
Even the new C6 Coupes have like a 2.6X Gear in them..
The C6 Z06 is like a 3.42, something close to that.
Go **** with that one..

The first mod to my 93 was a new rear with 3.55s.The spin cycle on my washing machine spun faster then my tires with the 2.59s.

Take that Washing Machine to the Track with ya and get a couple of pases out of it..

346Vette

All 1996 ZF6 6-Speed Corvettes got the LT4, not just the GrandSports. The collectors edition did not get an LT4 unless it was a 6-speed, in fact most collectors are auto and have the LT1.

The camaro y-pipe kills 10hp. The air box 15hp. Numbers are actual. I've seen the factory dynosheet.

Numbers are NOT actual. Look at any dyno sheets. Many LT1 M6s F-bodies pull 260-270 RWHP. Remember one BONE STOCK pulling 273 RWHP on a 1995 Formula.

The vettes dyno about the same maybe a bit less. You can only conclude one of two things

1. With only 4 or less % parasitic losses, GM has the most EFFICIENT drivetrains on the planet.
2. The motors were underated in the F-bodies.

I go with the later

all the 6 speed vette's come w/ 3.42's and dana 44's. The auto's get the d36 and worse gears.

hyperzone

huh? best record for what? I would think the C6 Z06 with an LS7 would eat up that LT5 all day....

Imagine trying to get parts for that LT5. haha... $$$$$$

They were talking about that LT5 somewhere else here.. It would be a damn good Engine with some Forced-Induction, but there is no aftermarket for it at all..

And definately X2 on the C6 smoking it..
Post this record that the C6 can't beat..

He's talking about the longest lasting motor for continually being ran, non stop for X amount of miles @ 175mph.

Cool..never heard of that one.

I'll say that with the rate that a few C6 Z06's have gone already..it would drop a Valve during that run..seen one here at the Dealership that did it, blew the Head apart..

The LT5 parts market is pretty small good thing that the engines are pretty much bullet proof. There is a stroker ZR1 running around here that is pretty freaking stout. Do a google search on Mike Ebert and ZR1.

The lt1 C4s with automatic were saddled with 2.59s, a couple of owners have dropped in a D44 with 3.45s and voila in the 12s with no other mods. Corvettes don't do as well on the dyno I guess its the IRS tax but they seem to hook P.D.G.

Yep, there's a true statement the the GS guys never want to admit. (GS is not all that special basically a cosmetic package on a six speed 96. I can't believe that some GS's have sold for more money than a similar condition ZR1s.

How do they test that? On a dyno?

aboatguy

In Fort Stockton, Texas at the 7.712 mile Firestone/Bridgestone test track. So the car was actually driven faster but you have to factor in the pit stops driver changes etc.
