Bought a motor for my 72 5.3L GenIII - anything i should know?

[JHART]

I just bought a 5.3L GenIII motor that came out of a 03 Silverado. It comes with all the electronics, only 44k miles.

I know i will need the wiring,swap to mech throttle body, ECU re-programed (To remove Emissions and VATS tables), new gas tank (baffled) and a few other things.

You guys think i will need much more?

Oh BTW i got the motor for $1500.00 I think it was a smoking deal!

Any input will be greatly appreciated! I will post pics of the motor when i get her home.
