5.3L to 6.0L swap

[SchreinerM]

Gentlemen,

I dropped a 5.3L from a 2001 Silverado in my '68 C-10. It's all painted and installed with a 2WD NV4500 tranny (from a 2002 Silverado) with exhaust and all. While looking for an engine for another project ('74 Pontiac), I came across a steal of a 6.0L in a 2002 Silverado HD.

Now I'm questioning if the 6.0L will drop right in place of the 5.3L (meaning existing exhaust manifolds lining up, wiring being plug and play, no issues with trans, painted accessories swapping over). If so, I think I'll clean up the 6.0L and drop it in the C-10 with the 5.3L finding a home in the Pontiac.

Please tell me it's that easy!
