Verify real LS1?

**Cayenne97** · 03-02-2008, 06:27 AM

I'm taking my buddy tommorrow to look at an LS1 motor for his '01 Trans Am. The original motor threw a rod. The motor he is looking at is said to be complete with the exception of no intake manifold or oil pan. What should I look for to verify that this is actually an LS1?

the fact that look completely different than any other GM motor ever made. i dont think i understand the question, u cant tell if its ls1, ls2, ls6?

its an engine, not a motor...

they are all aluminum and have exhaust ports similar to old school big blocks, where the center ports are not close together but all evenly spaced. see if you can get some casting numbers and run em

...Makes me sorry I even asked. I was trying to make sure I didn't mistake it for a 5.3-liter or something like that, or some other member of the LSX family that's a non-f-body/Corvette spec engine. Remember I said it has no intake.

dont be sorry. i just give some peeps hell cause soo many people say "motor" when its an engine. no biggy

the 5.3 will look similar maybe but it has an iron block with aluminum heads whereas the ls1 is all aluminum

i thought the 5.3 was aluminum and the 6.0 was iron. learn something everyday

Most people use engine and motor intechangeably.

Heres the definiton from websters:

"any of various power units that develop energy or impart motion: as a: a small compact engine b: internal combustion engine; especially : a gasoline engine"

As for verifying the engine, best bet is the casting numbers.

Well if you want to be politically correct, it is either...not that it really matters, just thought I would point it out to you. But like coke, pop, soda, or whatever one drinks, who cares!!!

motor - 1. a comparatively small and powerful engine, esp. an internal-combustion engine in an automobile, motorboat, or the like.
2. any self-powered vehicle.
3. a person or thing that imparts motion, esp. a contrivance, as a steam engine, that receives and modifies energy from some natural source in order to utilize it in driving machinery.

engine - 1. a machine for converting thermal energy into mechanical energy or power to produce force and motion.
2. a railroad locomotive.
3. a fire engine.
