LS1s are great, good luck getting thatthing to fit in your cobra. just use the motor you have now. or sell it and get an 03 04 cobra pretty much built already.

The above pictures are absolutely sick! I love old school Camaros, never thought I'd see one Ford powered though..
Have you ever looked at your torque curve(not just your peak). Go find a stock ls1 dyno sheet and look at its curve, enough said.
Wrong
The amount of air an engine moves determines the amount of horsepower it makes (within reason), and has little to do with BSFC.
Have you?
The LS1 is obviously going to make more low end torque than a mod motor, 281 vs 346. But let's not pretend that the mod motors are some kind of torqueless wonders.
My car makes 280 rwtq (320-330 at the flywheel) at 2200 rpm with a stock longblock, stock heads and oem Ford cams. Not too shabby for a n/a 281.

:lol1: Yes ill go pull the graph off the dyno tommorow of a bone stock 01 with 800 miles on it. And i have graph of mine. Ill post both and we can go from there.
How do you have 40 more tq than me at 2200, and what was your A/F at 2200 and at 5k -7k rpm. I was wondering that becuase somehow i dip into the high 11's. Isnt that a little too rich.
Way too rich.
When compared to other american v-8s they are torqueless wonders. However, they weren't made for torque so there should be no expectations that they will. Hence the reason Cobra's need 4.30s-4.56s to make it through the 1/4 quickly.
Here's a comparison of a modded Mach motor and stock LS1:

This is why I wanted to (and did) a 5.4 32V install.
No shortage of torque there.
God it's fun.

When compared to a 346 they are going to be down on low-end torque, I already said as much.
What is this graph of? Looks like a 311 rwhp Mach graphed against a bunch of 340-350 rwhp LS1s?
Here's my graph:
just buy an ls1 powered car..
WoW ! **Edited by moderator, watch it**why would u want to destroy a cobra with only 14k on it.. you should sell it to someone who will appreciate it and then drive a camaro off a cliff..
I wanted to do that also but thinking more along the lines of a 5.4 TT mod motor !

It's a bolt on Mach compared to a stock LS1
It's his car, it's what he wants to do, therefore he's not a jackass. Just because it's something you would'nt do doesn't make it the wrong thing. Also, the car can be put back to stock if he wants too.

I've heard of under rated, but that's a tad extreme. That rwtq # is what they're rated at crank.
I will say this once,
We all know that this idea causes some emotional issues for some but we will play nice.
Next jackass/idiot comment gets someone 2 weeks off.
And I'm not talking about 2 week vacation from work.

Think of it this way....
How much fun would it NOT be if everyone drove around in an LS1? Kinda boring if you ask me. Same can be said for mustangs. Its cool to have a certain car/motor people think its not fast then you show them what it can do.
Lifes a box chocolate folks...... don't worry I won't finish the saying.

Must be the world's strongest stock LS1, considering it's making more power than the early LS6s did.
Stock my ass.
I dunno:shrug:
Either that's the most liberal dyno on earth, or that LS1 wasn't stock.
Here's some more realistic comparisons from the same dyno.
My car: 1999 GT with 2005 Aviator engine - ported Mach 1 intake, JLT RAI, Kooks LTs, electric w/p, 01 intake cams, aluminum flywheel, full dyno tune:
2001 Camaro SS - SLP lid, Pacesetter LTs, exhaust, full dyno tune:
2004 GTO (5.7L LS1)- Longtube headers, cold air, full dyno tune:
2006 GTO (6.0L LS2) - Kooks LTs, Magnaflow exhaust, full dyno tune:
Yea, the bigger engines make more torque especially below 3500. Big shocker. But no way in hell was that a stock LS1.
