Default LT1 Vette vs. LT1 Fbody

What is the basic diff in the 1/4 mile between these 2 cars? Also, how does the LT1 vette stack up against an LS1 Fbody. Thanks for the help. I tried to do a search but it wasn't working.

well obviously the vette is gonna be quicker, but i guess it really depends on the model year and condition of vehicle, and thats if your talkin stock vs stock

A Corvette will run about .3-.5 tenths quicker do to a better induction system, exhaust and better stock gearing. (They are rated at 300hp)
There are some other little things, and the suspension helps them hook good too, not to mention the Vette's run 275's.

The stock exhaust etc. is a little better but the primary factor is the reduced weight of the vette compared to the Fbody.

Oh and what they are "rated" at doesn't mean ****.

I'm just sayin, it's well known that GM created a disparity in ratings between the vette and fbody to make it seem like the vette version of the LTx/LSx was better, when in fact it wasn't and they will both dyno very similar. So I don't really get why people keep insisting on giving the "ratings" much weight.

GM listed them as more powerful when, in reality,they're identical. if anything the f-body makes more power cause the solid rear eats up less power. the SS, firehawk, ws6, etc. actually make more power because of their induction and exhaust upgrades. GM just couldnt have their precious corvette being less potent then its little brother, the f-body. people would go, "well ****...this is 20k more and has less power. F that S."

Not really applicable but I can vouch for the L98 Vette being WAY slower than a stock F body. I absolutely destroyed one back when my car was stock. I have a few things in my favor (me 6 sp, him auto), but still, it should have been closer than it was figuring that .3-.5 faster idea. An L98 at a .3-.5 faster should have been almost even with the Lt1 f-body.

I know that doesn't help much, but my $0.02

Thanks for the info. I've got a guy that wants to trade me a very low milage 6 speed LT1 Vette for my 2000 WS6. I was wondering what the performance diff was. I had a 95 Z28 with a couple of bolt ons & it would run 13.8 to 14.0. I always thought that an LT1 Vette would run about the same as a stock LS1 Fbody mid to high 13's. I'm probably crazy to even consider doing the swap. Thanks!

if someone offered me a LT1 (later model) vette for my car id do it, i want to put my motor in one of those suckers, noone expects them to be fast and they are lighter

I dont know about the lt1 vs ls1 but...

An lt4 vette or f-body can follow an ls1 (even the ram air one) without no problem in stock version.

My stock '94 vette ran high 13.8-14.0 at about 102mph. 2.0 60' on typical worn street tires. Most magazines in the mid 90's got the same times I did. The true dual exhaust is about the only positive over the F body in terms of power.

I'm sure there's a lot of exceptions, but on the tires they came with and typical drivers, I think the f bodies run average 14.6's right? a tiny bit of that is power, but mostly traction.

Since I have owned both I will offer my experience. The LT1 Vette is far superior in every aspect. The Vette hooked up much better and ran a 13.7 at 102 mph stock and 12.3 at 117 on nitrous. My Camaro ran high 14's at ~95 mph stock.

If you ran high 14s then something was not running right or you couldn't hook or something else.

low 14s is the normal stock time for a car with no issues.
