Does anyone know how much faster a LT4 is over a LT1? 0-60mph, 1/4 mile, and top speed? From my research, it does not appear to be that much more, except at the top end.


Thanks in advance.

Auto ?


6M ?


Performance axle ?

30hp= what in the 1/4?
Driver / tires can be worth almost that much.

The lt4 car is a manual trans car. This means for the majority of drivers its slower at everything except top end.

I would say lt4 would be about .4 to .5 faster in 1/4 mile...but you will feel the difference in everyday driving

Wow!!!!
So, you're saying he's asked the same "idiotic" question 5 thousand times? Hmmmmm......and you've kept track of the count?

In everyday driving, I cannot feel the difference.
Only when you take both to redline will the difference be noticeable....and not many of us take our cars to redline on a daily basis.
Both the MN6/LT1 and the MN6/LT4 pull just as hard up until about 5700rpm.
That's been my experience, anyway.

Excuse me. I was a Forum member for many years who sold his last Corvette more than three years ago during a divorce. Upon returning this year, I just wanted to initiate a simple conversation about these particular motors, since I had bought a 96 model. I know how to research these motors, but I just wanted to have a friendly conversation again with other C4 enthusiasts. Its been more than twenty years and I was curious about long term performance.

Many times in the past here I would see the same comments from newer folks. No need to get mad at them. In the future, please ignore my stupid posts.

Have a good day.

Thought I was only the 4,875 idiotic post? Doing pretty good.

Dyno graph comparisons agree entirely...

EDIT: (see graphs for specific details...)

Buy the lt4....

Buy a C5 6M for the same money.

If you like c4s....buy the lt4....if you want the "better " vette then but the c5

There seems to be disagreement about this. Some say you will feel the difference and others say you will not.

I agree that the dyno sheets show very little difference until the higher rpm and that lower rpm street driving should not see a difference.

However, I have a '95 LT1 6m and a "96 LT4 6M and there is a noticeable difference in normal driving. On my cars the LT4 pulls stronger. Although I like to run them, I usually only go up to about 5k in normal street driving.

I guess the best answer for you is to try driving a couple and make your own conclusions.

Edit:
Since C5's were brought up...

I also have a '99 6M with a few minor mods. The C5's are very different cars. They are nice too, but driving them doesn't feel the same as the C4's. I enjoy trading off between them.

My LT4 is as quick as my LS1.

Again, drive a couple and see if they are right for you.

The LT4 is faster than a C5.

I don't see why an LT4 C4 would be faster than a manual C5. stock vs. stock. Curb weight and rear gear ratio is almost identical. 3.45 330hp vs 3.42 345hp. I think it would come down to who is the better driver.

Although I know on the 97-00 cars, a manual C5 is about 1/2 second faster running a 1/4 mile than an auto. So an LT4 is probably faster than an auto 97-00 C5.

This has been discussed A LOT. Based on many who actually raced both cars in San Diego during 1997.

A race between an M6 LT4 and an M6 LS1 was a drivers race.

A winner between the LT5 and LS6 was the LS6.

Never saw a race between an LT4 and an automatic LS1 C5.

in 1998 I raced my 92 with a brand new 98 Z28 LS1 and he spanked me three times back-to-back-to back. I never had a chance.

rocco16

That has not been my experience.
The LT4 and the LS1 are very, very close. The LT4 cannot run with any of the later C5's.
