Can Anyone Help Me Identify My Vortec 6000 Engine?

[ccitsolutions]

Hello everyone,

I recently inherited a 1985 Chevy C10 that has been engine swapped. The engine cover says "Vortec 6000," but I'm not sure exactly which 6.0L engine it is.

I'm hoping someone can help me identify it so I know what year, make, and model to reference when ordering replacement parts and adding accessories in the future. I'd like to know exactly what engine I have before I start buying components.

If anyone can identify it from photos or let me know what information or casting numbers you need, I'd really appreciate the help.

Thank you in advance!

That cover is a Lq9 cover, but they fit any Gen 3 truck engine from 99-06

They way to tell is the block is cast front and rear with either a 4.8/5.3 or a 6.0.

Then scope the piston to see if it's a flat top or not. Yes = LQ9 No = LQ4.

But they all do burnouts and run way better than the old Gen 1 stuff anyway.
