Small block or big block engine?

[Z71Tahoe2004]

Been looking for some background on engine size regarding the "block" size. Most of what I've found talks a lot about Chevy's history with block size engines and deal mostly with classic muscle cars.

Wondering what my 2004 Tahoe 5.3L FFV engine is? Presuming it's big block?

It's an LS engine which has the same bore spacing as the classic chevy small block. 4.8, 5.3, 6.0, 6.2 motors all have the same foot print and configuration, even the 427 if memory serves too. It's not hard to stroke these things to over 400 cubic inches.

So the 2004 chevy tahoe is a small block?

Yes, regardless of which engine you have..4.8, 5.3 and 6.0 are all small blocks.

I'm not sure the classic 'big block' and 'small block' labels still apply. As a guess, I'd think the current LS engines might all be considered 'small blocks'.

If this helps any, 1 litre is 60 cubic inches (61 actually).
