What kinda comparisons are you looking for?

the LS1 is a better motor, but more expensive.

good enough? what kind of comparisons do you want? i suggest you research them yourself and go from there.

The reason I asked, is that I disagree with you on half of that. I don't think the LS1 is any better than the LT1. The LS1 makes more power stock for stock, but that doesn't mean it is a better motor.

Both have advantages and disadvantages.

i dont think you will be able to find a site comparing the two..... your best bet is to do your homework and make a comparison yourself.... in my own opinion i think the two are very much alike when you weigh the pros and cons with the lt1 just a little bit ahead in the reliablity/strength side....

I personally like the LT1 better myself, i like the whole concept of the reverse cooling, getting the cooler anti freeze through the heads first. And then when you make it an LT4....

i was looking for a link to a thread on this site. talk to me like a lost child also when it comes to comparing the 2

LS1 = Aluminum heads and block. Lighter. GREAT flowing heads. Actually a 346ci. Gen III GM small block. Strong to about 500 horse, roughly.

LT1 = Iron block, thus heavier. Heads are the down point. Good flowing heads, and they make damn near LS1 numbers. 350ci, Gen II GM small block. Good to about 550-600 horse.

That is a basic breakdown. LT1 pulls harder down low, and the LS1 is a beast up top.

thanks luos

luos, where do you get you numbers on the engines as far as what they are good to?

from an engineering perspective, the LS1 is superior in almost every regard than the LT1.

Engineering, yes. Keep in mind the LT1 is an iron block over the LS1's aluminum block. Iron is stronger than aluminum.
They both have their pros and cons. The numbers I posted are very rough estimates. I have seen stock heads and stock cam'd LS1's make over 700 RWHP. Of course, it takes 13.5 PSI from a turbo, but hey.......
Both motors are GREAT with a proper tune. Both can handle a ton of power.

iron stronger than aluminum, yes, this is true, but not by much anymore. also the aluminum not only cuts weight, but dissipates heat faster allowing higher compression levels. however the LT1 runs two bolt mains in most, and 4 bolt mains in some applications. The LS1 has six bolt mains, two of which are horazontaly installed. for a far more solid bottom end and allowing a higher rpm potential. the rotating assembly is lighter, the intake manifold is composite, and is sheilded from the oil galley, which conducts far less heat than the LT1 aluminum intake manifold did into the intake charge, the heads are far better designed and are far more securley attatched to the block, the valvetrain design is leaps and bounds beyond the LT1, using retained lifters, conical (beehive) valvesprings, and a rocker arm retainer system that is in essence a shaft rocker system, Individual coil igniton, and more advanced computer controls. the LS1 kicks the crap out of the LT1 and steals its lunch money.

not be a pain iroc but is there any thread dedicated to explaining all the pros/cons of these 2. i was trying to not make a clone thread so a link would be greatly appreciated

Stock for stock, agreed.

But once you are talking about getting into serious mods, either is great. I own the LS1 car, but I very much so respect what can be done with a lot less money to an LT1 car.

Here's something to throw out.......Iron block 402 LS1????

89IROC&RS · #15 01-07-2005, 02:42 PM

well shit, if your talkin mods with alot of money then pretty much all engines are equil. im talking the base building blocks of either engine. from a comparison of each and what qualities they have, the LS1 is a much better engine.

as far as being a clone thread, i think this is one of the better LT1 vs LS1 threads, what is it exactly you are looking for??? a bulleted pro and con list for each?
