Default Main cap install

Im starting to assembly my shortblock. As i look at the mains i noticed their all numberd 1-5. 1-4 the numbers are all on the same side of the block. Should the number 5 main have the number on the same side as well? It just doesnt look like its right when the numbers are all in a row. If i have the 5 on the opposite side it looks correct.

Also is there anything i need to do special when installing the timing chain? As long as i line the timing dots up i should be ok?

You are correct 1-4 is on one side while number 5 is opposite at the other end. If you look closely you can see that the main cap side bolts are slightly offset to the center of the caps. This will help you know which way to put them in ;-) Also, not sure if you had the crank balanced and assembled at a machine shop or not but you have to check all your clearances and crank end play etc. If you're not sure then go to your local parts store and get a plastigauge and do it yourself. They're about $6.00 but worth the piece of mind in the end.
