All the "evidence" I've ever seen for the purported better low end of the LT1 (vs. LS1) is all from Butt-O-Meter response. Dyno graphs show otherwise.
Wrong. You just proved to us that the LT1 is better from idle to 3000 rpm.

No, because traction is the main issue in the 60' with a stock car, not torque. As soon as both cars reach 3000 rpm the LT1 doesn't have a chance, but put a 3000 rpm rev limiter on both cars and the LS1 doesn't have a chance.

You already proved the LT1 is better from idle to 3000 rpm and the LS1 better from 3000 rpm on.

Are you serious? It sure as heck isn't from spending anytime....at all....below 4000 rpm. None.

Well whoop-de-****ing-do. What does that do - make it a better tow car?

Why on earth would anybody even consider such an assinine thing as a 3000 rpm rev limiter on anything short of a diesel or a single-exhaust 1 bbl 352 CID FE Ford? Who cares? If that was the metric in question, go get your favorite diesel pickup truck and out "feel" everybody.

And if I want to "feel" more torque, I'll simply add some gear.

Yes I am serious. Let's hear it.

No it makes it much more fun around town from idle to 3000 rpm. Ever heard of drivability?

I was just trying to prove that the LT1 would win in this case.

LOL.

LS1 vs. LT1

What a surprise. The LS1 is not the king of every category. Hasn't this one been ground into the dirt already? LT1 is more responsive and has more grunt, sounds better. LS1 pulls up top like a freak show and is awesome to mod. Sheesh.

Re: The LT1 is a torque monster compared to the weak a** 4.6.

Hahaha... I guess I just showed what I said wasn't true

I bow to the superior low end grunt of the LT1

Be warned, this won't be the last time that I'm wrong

I don't know about others, but I'm not fighting... I just want proof... even if it proves me wrong

I would also enjoy seeing some good testing. The problem is coordinating-

You're going to need several LT1s and LS1s just to show that it's an average.
All vehicles will have to be at operating temp.
Even synthetic oil can give a few hp on top compared to conventional.
They all need to be stock- having intake & exhaust results would be nice also to show how the powerbands shift.

I suppose if there's enough people from one area on this board they might be able to pull something off.

It would be a big PITA, but I'm sure it would make a great sticky at the top of one of the forums. Or all of them.

You want to hear it? Ok. It's a stupid arguement and a stupid point. No races are won 2000-3000 rpm below redline.

No man, I ride my bicycle everywhere. If you get your rocks off running from idle to 3000 rpm, then more power to you, and I still suggest a turbo diesel. You'll be happier.

I was just trying to prove that the LT1 would win in this case.
Let me concede right now: If I had to race an LT1 (in my 99) with a 3000 rpm rev limit, I'd lose. It would be a stupid, useless, and pointless race that nobody with a pence of brainmatter would engage in, but if I did, I'd lose.

There. You heard it.

BTW....torque does win races...when multiplied by rpm. But wait! That's HP. Imagine that.

Thats why I love my lt1.The unmatched pin you back in your seat torque from a stoplight.I have test drove two ls1 camaros,and they just dont have quite the low end punch of an lt1.They definitely make up for it with their awesome mid to high end torque.I dont care what anyone says(bob cosby)the ls1 is not near as fun from a stand still as an lt1.

Shipmate, if you have more fun from a standstill in your low 14 second car, then more power to ya. I'll take the "less fun from a standstill" low 13 second LS1 any day of the week, and twice on Sunday eliminations.

I guess you win the 0-5 mph race (on street tires, on the street, and nowhere else). Congratulations.
