Well my dad just got a 04 Chevrolet HD 2500 4x4 silverado and its got a vortec 6.0. Well is this a big block 396? Does that make since since the 350 is a 5.4 and the 6.0 could be a 396. Surely it isn't a 383 stroker.

A 350 C.I. is 5.7 Liters!!!!!!

A 6.0 Liter is a 366 C.I roughly!!!!!

These are off +/- 3 C.I.

they are not the same family of motors...
the new motors are based on LS-1 generation. (4.8,5.3,6.0)
the old motors are based on LT-1 generation.
(305,350,383,400)
they are completly different.

just to get alittle more technical the 5.3 is a 323 and the 8.1 has more a mix of old school rat and new tech has no relation to the gen III small blocks. and the 5.7 in gen III motors was a 346

1.00000 Liter = 61.02374 Cubic Inch

Here is a nice online Displacement calculator.

a 400 is 6.6L, remember the old firebirds? and a 454 was 7.4L. I think the formula that was listed above answers it all along with the other post that references them being completely different family of motors.
