Ls1 = Lm7 = Ls4 = Ls7????
Ls1 = Lm7 = Ls4 = Ls7???? First of all, I'm not ignorant as ****, I just need some of you guys to back me up.
A guy on another forum is trying to tell me that he's got an iron block LS4 that came out of a Z71. He keeps telling me that since the 5.3 is GenIII technology, that it's an LS based motor and that he's just going to call it an LS1 because "all the guys on LS1tech.com says it's the exact same motor". And, since he doesn't seem to think that a real LS1 is worth what the market is baring right now, that he's going to go the 5.3 route, sheerly for economics. As a matter of fact, he even read on this forum that someone took a 5.3L and bolted on LS7 ****, and now he's got an iron block LS7.
I know that all these engines share very similar engineering but are not the same engine.
So, please. Could someone who knows their *** from a hole in the ground settle this?
If you would like a fine read in colossal ignorance, check this thread. My user name there is Eat-Pez, just so you don't get me confused with the dipshit.

to be honest it just looks like a pissing match over technicalities. 323 or 325 who cares?! LM or LS, again who cares?!
the only thing that really matters is what can and cannot be done, and you can swap parts from LS to LM, and LQ too. so who gives an F.

You're right. Many parts are interchangable, many are not. You can't put an LS1 piston into a LM7, and you can't put an LS7 intake on an LS1, just to name a few. And you can't take a motor from a Z71, put it in your car and say, "Check out my LS4."
yeah, i got ya, but i think that "for all intensive purposes" is being ignored. like "for all intensive purposes an lm7 can be used in place of an ls1" in the end they really arnt that different. aww well.
They are all pretty much are the same with little differences this is why most people just call there build an LSX based motor. Usually even when using the Lq9 block with the ls style heads its usually labeled LSX only real reason is manily most people don't know the difference between the 2. And everyone know what an ls1 is even ricers how many people know what and Lq9-Lm4 is even gm now calls the L92 motor a Ls3 in the vette just cause of minor changes most noticeable the intake.
Same goes for LT1, LT4 and LT5..unless of course you own a ZR1

Nobody's arguing that you can't use an LM7 in the engine swap, of course it can be done, but the fact of the matter is that you can't bolt LS7 accessories onto an LM7 and say, yay, now I've got an LS7 too. And arguing about it being a 325 instead of a 323 really is just a technicality, but it proves the point that the kid a.) Doesn't know what he's talking about and b.) Won't listen to reason, even in the face of solid proof.

My vote goes for LS1 and other Gen III variants are all part of the same family...as are Gen IV motors, but each member is a different namaed entity. For example, my last name is Sheets. I have two brothers, all of us belong to the Sheets family, but only I am Tim. To use the terms interchangebly for marketability purposes is not technically correct. To continue to do so and deny facts moves you from the family of ignorance to stupidity.
Sure we can mix and match and lose some of our engine's identities. I'm running 853 castings (customized) on my LS1 engine that is from an 02 SS
which actually had an LS6 block casting...some families If my brother wears my clothes does he take my name??
I still consider my engine an LS1...for all "intents and purposes."
