Seems like u have planned to complete before your departure. good to see engine getting installed.
make sure u paint all the necessary things black including the radiator, the gadre which holds the engine, head cover of engine, block, iron pipes coming out of engine etc
remove all the unnecessary pipes etc.
pic 1& 3 are the areas which needs to be addressed with coloring
pic 2 is the nut which has rubber cover on its top and it holds the bonnet.
