what motor do i have?
i have a 243 stamping on my heads witch is ls2 heads i know....
the guy told me it has a ls3 in it i have a feeling it is not a ls3 for sure beacuse ls2 heads wont bolt to an ls3 i dont think unless doing some conversions
from what i read the ls1 has a knock sensor under the intake and not on the side of the block
however the block i have has a knock sensor near the oil filter
here is a pick "im pretty sure its a knock sensor"
sorry for bad quality i took with my phone =/
any help will be nice thanks!

They used 243s on other motors like the 5.3 FWD LS4 & we had a 5.3 truck in the shop the other day with some 243s on it. They will bolt to an LS3 but I dont know why someone would when the LS3 heads flow so much better unported.
That sure looks like a knock sensor plug, blue wire too.

All the gen4's have the cam sensor in the timing cover so that would'nt tell him anything unless it's a known 2005 or 2006 year engine . Pull the crank sensor right behind the starter and look in there with a flashlight or something and turn the crank and count .

It "could" be an LS3 with Ls2 heads and an LS1 intake... if they were trying to throw it together cheap.
I would guess a Gen IV motor, with the knock sensors on the side. I don't know why someone would go through the trouble to relocate the knock sensors on a Gen III.
Hard to say without more info.. Is the block made of aluminum or iron?

In your other thread, you state that the seller told you the car has the "LPE conversion".
https://ls1tech.com/forums/14770561-post12.html
This "could be":
Their 58x to 24x converter box OR
They changed the block sensors to work with a LS1 PCM.
This deepens the mystery. Could this be a 58x motor?

I do think you should've asked a few more questions before you bought the car. This is not saying you got ripped off but it'd be nice to know what's custom or "non-original" on this car-so you could service it.
Is the block aluminum? Can't tell? See if a magnet sticks to it. How many knock sensors do you see on this block? Is it possible that the plug in your picture is an engine block heater?
