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.

Fuel mileage has a lot to do with gearing and other factors, not just efficiency (6spds in the ls1 cars > 5 spd in the Cobras.) The real definition of engine efficiency is how much power it makes in relation to CID. 317 lbft tq from a 281 cid engine is more efficient than a 346 cid engine making 340 lbft tq. Now, I'm sure the LS1 is underrated as well, but my bone stock 281 made 343bhp/tq while only rated at 320/317. Not saying the LS1 does or does not have more potential, but it is not a more efficient engine stock for stock. No arguement there.
I dont know how the concept is hard for you to grasp, a motor with 1.1L more displacement getting better mpg than a smaller motor is more efficient:rollseyes
But thats fine you can continue to be an ignorant idiot if you want. Its not a some kind of top secret info, and engine is a air pump thats all it is. An ls1 just happens to be better at pumping air than the mod motor.
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.
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.

Way too rich.I was wondering that becuase somehow i dip into the high 11's. Isnt that a little 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:
I thought of doing the opposite. I want to put a cobra motor in a ws6
What is this graph of? Looks like a 311 rwhp Mach graphed against a bunch of 340-350 rwhp LS1s?
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.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!
It's a bolt on Mach compared to a stock LS1

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:
