Tuned LT versus SS who win?

Uh........ can you do that?

[SlingShot]

You would have to do some custom mounts and wire, but it would run .......

I've read a few blogs that they may be going to the 3.8 in the future.... Have to wait and see.... The Grand Nationals use to run 12's in the 1/4 ..... That's good and still get 20 mpg with A/C and full power... And Free Bird blasting .....

wow, I feel so much smarter now.

On the off chance that you're not just jerking people around by posting nonsense...

If the GN engine was stock, yes, it would get smoked... badly.

Put maybe $1,000 - $1500 into the GN/Camaro and it'll run with the SS.

Nonsense ? 1987 Grand National 3.8 Stock GNX 0-60 5 sec. 1/4 mile high 12's


And you still say it will get smoked by a stock SS.... The numbers are pretty much the same for both cars.

Total nonsense.

Where in the world did you come up with high 12's for a stock GN?

[SlingShot]

Typical write up for the 87 GNX...... But in the last year of production for the Grand National ( GN ), the GNX was created and it beat the Corvette hands down on the 0-60 times and the 1/4 mile times, making it the fastest production car EVER made at that time. The GNX had a 0-60 time of 4.7 seconds and a 1/4 mile time of just over 13 seconds and it was a sedan!! So GM pulled the plug on the Grand National because of the Corvette.

If you take the time to look around you will find many videos of GNX runs that are way below write up times. I don't know what your definition of smoked is, but running better with less than 1 sec time is not smoked ..... Don't forget we are talking about stock V6 Vs. V8

It's a fact that engines with shorter strokes and higher compression will take it off the line, but the longer stroke will ramp up and ultimately win. It's like comparing a 2 stroke against a 4 stroke, the 2 stroke is made for bottom end high RPM ....

First of all, using the GNX as an example of what stock GN's could run is like using the ZR-1 as an example of what stock Corvette's can run.

Second of all, most published GNX runs were in the 13.3-13.4 second neighborhood. I think I saw one as low as 13.12 or something like that but that was definitely the exception.

A regular, stock GN typically ran 14.1-14.2.

So GM pulled the plug on the Grand National because of the Corvette.

GM pulled the plug on the Grand National because Buick Regals went to FWD in 1988.

No you won't, because that's all the faster they will go stock... and hardly anybody modded GNX's. You will find plenty of 11 second GN's, though... but those are all modded.

It's a fact that engines with shorter strokes and higher compression will take it off the line, but the longer stroke will ramp up and ultimately win. It's like comparing a 2 stroke against a 4 stroke, the 2 stroke is made for bottom end high RPM ....

I don't know what "bottom end high RPM" is supposed to mean but somewhere in a prior post you said small blocks have better bottom end torque and power than big blocks... which is patently ridiculous... so I'm not going to waste time debating that with you.

What if we could put the booster rockets from the space shuttle in a LT...would it win then?

This guys is wearing me out.

Negative. Stock vs. stock the ls3 has anywhere between 80-150 lb/ft more than the 3.6DI across the entire rpm range. There is not enough of a gearing or weight difference to help out the LT, even with a tune. A SS would already be pulling away shifting out of first gear.

The big block does much better from a roll ... Same principle V6 against V8 .... Both are governed for the same top end ..... Don't forget the Lt is tuned and the SS is stock ... ( with proper tune it is very possible )

Ah your just a youngin I take it ..... Besides all this was purely hypothetical ....

Just to clear it up, a small block called such because of the physical size of the block, and the same with a big block. Has nothing to do with the torque curve of the motor.

Next, it is impossible to say a big block is always going to put out power in a certain range, same with a small block. It all depends on how the motor is built, and what cam you have in there. If you were going to generalize, then you have it backwards. I'd say a big block would have a lower powerband than a small block, so a big block would smoke it off the line, and a small block would catch up when it gets up in the rpms. Generalizing, big blocks are better than small blocks for low end power.

Also, NASCAR has absolutely no use for low-end power, none. IIRC they spend almost the entire race around 8k-9k rpms. That is where you need top end power, not bottom end.

It might, maybe keep up with a SS, but a GNX was about ~200lbs lighter than the body you're talking about putting it in, so its not gonna run nearly as good. You'd do alot better just buying a SS; that GNX motor, with its turbo, plumbing, intercooler, and cast iron block is going to weigh more than a ls3; not to mention the cost involved to do a swap like that right. I'd rather just cut to the chase and buy the SS and the warranty it comes with.

Again, really depends how the motor is built, but if I were going to generalize I'd say you have it backwards. A motor with a longer stroke generally will not be able to spin as fast as one with a lower stroke. Generally people build 'strokers', engines with longer strokes, for low end power; and engines with less stroke for high rpm power.

FYI, 2 stokes havent been used outside chainsaws and bikes in a long, long time. Don't know why you bring em up..

Well if your gonna do that then your gonna have to put the old f-1 saturn V rockets on the SS to make it fair. But the SRB's make 1.8 times the boost as the f-1s, but a ls3 can get like 60rwhp with a cat back and a tune so I'm gonna say the SS FTW.

Geesh I see they are allowing the residents of the mental ward time on the internet again

[glambert1]

is it really neccessary for everyone to try to make others out like they are idiots for just asking questions
