have any of you guys driven a 1999-04 mustang gt? If so how does the power compare, LT1 to the 4.6? Im getting rid of my gt and getting a z28 next year but i dont want to get something that is not any faster. I know you all will be biased about ford vs chevy but I like both and i want a honest answer.

stock? the LT1 will have way more torque, it runs a on average 14 flat stock with a good driver so take that as you will compared to a 99+ 4.6L. also the Lt1 responds really well to mods, bolt ons and a cam can net you ~340+rwhp and run mid to low 12's at 110+ easy. ive driven 99-04 and my gf and i have a 05 GT, 3 valve, it lacks power down low but up top is where it comes to life. stock it was a slug, but with exhaust and a cold air/tune it picked up 60rwhp and tq. but thats a 05+ 3v the older ones were nothing like that.

I don't mind Mustangs. From 1993-2002 the fbody was unquestionably faster and more powerful year to year. I don't think you'll be disappointed with an LT1 fbody. I can honestly say that, right before I did the LT1 swap a couple years back, I drove a 2002 Mustang GT A4 w/ 25,000 miles. It felt extremely sluggish compared to my A4 LT1. And I'm comparing it to my LT1 when it was stock (with the exception of the muffler being removed) with 2.73 gears. Also, I've never ran up against a GT of any generation that I didn't beat.

They might be faster, and have more potential, but LS1's look like a fish I wouldn't eat.

I love LS engines, they're amazing. The three main things I consider to be important when considering a car of this nature would be:
1) Appearance
2) Sound
3) Performance/Potential

In my mind, LT1 wins #1 and #2 hands down. #3, LS1 wins in potential only. The potential for this engine is greater than that of the LT1. But other than that, both can be made to have 400, 500 and 600hp very easily, which is more than 99.999% of car owners will ever want or need anyway. Also, both can easily be made into 12, 11, 10 and 9 second cars. Anything beyond that is purely ridiculous. It's really all a matter of personal preference unless you plan on going crazy with the build. Either way you go, you're going to get a mean car with the power and potential to outrun almost every car you come across.

Haha, I cant believe you guys are still even debating this?! GM small block evolution peaks with every generation. With the exception of smog/fuel mileage related self-imposed restrictions in the 70s and 80s, never once has small block tech regressed. The LS series engines are far superior to LTs, from the bottom up. 6 bolt mains, more efficient head/intake designs, ALL alluminum, easier serviceability...not that an LT is hard...more bolt-ons, better ignition, better oiling system...can go on and on. The only thing in my opinion, and it is STRICTLY my opinion that is better about an LT1 is the sound...but that is probably because I have 2. Now you can get into the interior...better fit and finish, less creaks and rattles...again not that LT interriors are loud...but the center console is MUCH better, extra cup-holders etc. This debate is like saying whats better an LT1 or TPI?

Come on guys...this is not a hard one.

5,000 will get you a rough LS1, or a decent LT1... IMO, it is better to look at it as an investment pertaining to the length of time you intend to have the car...if you have time to work on it...go LS1. If you want to jump in and look good right off the bat, find a great looking LT1.

They are all coming down in price...FAST.

The LS1 cars certainly don't have better fit and finish than the LT1. They all creak and rattle...or will soon. I agree with the console upgrade comment, though...

Take a look on ebay, the prices of 2002 Trans Am's are not coming down at all...maybe since they're the last year people think they command a premium. The older cars can be had for anything ranging from a good deal to 'you must be high'...

My LT1 has the same interior as every LS1 Camaro had. Don't forget, LT1's got the new interior at the end of their run. What we're saying is, if you're not looking to go 1000hp (for example) an LT1 will do just as much as an LS1 and in most people opinions they look AND sound better. So you get a car in great shape vs a car in poor shape, with better style and better sound and you're not giving up much in terms of performance. Each car is capable of hitting 400, 500 and 600 hp easily. It's really preference over anything else.

Can't argue this one, but I wouldn't be surprised if the LT1 was higher amp than the SBC one.



Electric water pump about the same price for each. Actually slightly cheaper for the LT1



True.



You can run these on an LT1...



Only noobs use the LT1 starter. My LT4 starter was like $110 new. Granted, that's still more expensive than the SBC... but it's a much better starter I'm sure.
All great points.
Autozone parts are often defective poorly refurbished parts. I picked up a couple cheap tools and some break pads there before, but that was it.

Talking

My second job is at Autozone...you would not believe how fast the batteries come back! It is like they ALL fail right outside of the warranty period, I would NEVER buy a battery from Autozone. DONT EVEN GET ME STARTED ON HUB ASSEMBLIES!

P.O.S. Duralast crap.

Dont tell my manager I said that
