like jdaniel says. The LT1 and LS1's have 1.1 liters on us. Considering that, i think we do fairly well. Our V6 pony siblings are only .8 liters smaller than our 4.6's. So let us drop in a bored out 5.4 liter motor from the Ford GT and lets race.

All in all it took a detuned corvette engine to take a Mustang down. Now that Ford has produced the Terminator ('03-'04 Cobra) all the Chevy guys cry that it isnt fair. What isnt fair is that we are lacking 1.1 liters and the addition of a blown motor is more than fair enough. Hence my signiture. [quote]

i'm not trying to start anything here because i am going to get a mustang but the ls1 is all motor and on the 03+ cobras ford just bolted on a s/c. but i just thought i would lay that fact down. i mean don't take this the wrong way because like i said i am going to get a mustang.

Ummm... So by that you mean by Chevy replacing the crappy engines they used to use with a Vette engine is okay?[&:]

well i'm not trying to start something here[:'(] but i am just saying ford could have done more work on the motor than just bolting on a s/c.that's just my $.02. i agree with you that a newer cobra would beat a z.

Well the 4.6 is a what...281cid right? The LT1 and LS1 motors are 350cid. So both can produce a lot of power. But, pound for pound the power of the 281 is not going to touch the power a 350 can produce. Another thing you have to take into account is which one is going to hit there peak horsepower first? ALL of the 93-02 Camaros hit their peak HP @ 5,200rpm. Another thing you have to think about is the torque. All of the 93-97 Z28 models have 325lbs of torque @ 2,400rpm. 98-00 Z28 models have 320lbs of torque @ 4,400rpm, and all of the 01 and 02 Z28s have 335lbs of torque @ 4,000rpms. (I don't know any of the 94-02/04 Mustang RPM or torque specs.) Anyone??

yea 99-04 mustangs can hank with lt1's. Just the other night i raced a 94 z28 modded out the *** with a shift kit and all and o losedd yea, but never saw his back bumber i a QM. now when i gonverd out at 123 or 124 he kept going-----------damn ford for governing out the 99 mustang.

Almost everyone in here is right....it's a tuffy.....but mostly deends on a driver.

Close but about 25 hp short of average.

jdaniel

So 25 hp... that actually all comes down to difference in weight and driver experience.

hello everyone, its been while.

i think ford did a great job with the motor. specific output is a great way to compare engines,

ls1, 325 hp (i hope that's right). 325hp/5.7 liter = 57.0 hp/liter. nice & strong output.
99-04 GT, 260hp/4.6 = 56.5 hp/liter, nice & strong output
03-04 mach 1, 305hp/4.6 = 66.3 hp/liter, even nicer & stronger output
99-01 cobra, 320hp/4.6 = 69.5 hp/liter, even nicer nicer & stronger stronger output.
03-04 cobra, 390hp/4.6 = 84.78 hp/iter, i wish i had niceness & uber output.

anyway you dice it up, all the motors are strong for what they are. the difference in times comes from the package.

i welcome all critiques.
