If I look at the vin# can I tell if it is a lm7 or lw9 I'm asking cause I have a 01 Tahoe and 01 suburban that is totaled and pulling the 6.0 out to put in my Tahoe and I don't like aluminum heads
I think 1999 & 2000 were the only iron head years for the 6.0. These engines also had a longer crank.
From Wikipedia:
4.00 in bore blocks (1999–2007)[edit]
The 6.0 L is a larger truck version of the LS1, with the exception that the blocks were cast of iron, and was designed to bridge the gap between the new small blocks and big blocks in truck applications. There were two version of this engine: the LQ4 and the LQ9, the latter being more performance oriented. Although the block of the 6.0L looks similar to the LS1, they are iron instead of aluminum.
6.0 L[edit]
The Vortec 6000 is a V8 truck engine. Displacement is 6.00 L (366 cu in) from 101.6 mm (4.00) bore and 92 mm (3.622") stroke.
