Engine swap for Tahoe z71

[Martin Luther]

I was given an 05 Tahoe 5.3L type T engine. I am wondering if an 03 Tahoe engine will fit as a replacement? It's too good of a deal to dismiss. Any thoughts?

Yes and no...

IIRC, 03 didn't yet have e-fans so the 03 engine is going to come with a fan on the front. As far as other minor differences I don't know. But they're all the same basic engine, you just may have to swap some parts from your 05, onto the 03.

If I understand post correct, OP was given an '05 Tahoe equipped with an LM7 (VIN T). He wants to know if the motor from a 2003 will swap in, correct?

Short blocks should swap no problem. The rest I would defer to the others on.
