318 crankshaft specs

The year of the engine does matter.
The engine book i suggested you get, and you replied that you have not only one but two mopar small block engine books,they are what you need to look at.:read2:

The pistons weight is what matters per year.
A crank out of a 273 has a piston weight of 530grams.
A crank out of the same year 318 has a piston weight of 592grams.
If you go to use a 273 crank ,you will have to have it balanced to the 318 pistons USING MALORY HEAVY METAL$$$$$$$$$

You need to have the crank balance.SO....
If you find a 340 crank, you will have to balance it, BUT i believe you will only have to have weight taken out of the crank, due to the 340 pistons weight being .720 grams.
The shop should only drill the crank and not have to add malory heavy metal ,and that get's very expensive.
Look at the list and find out the weight of your pistons to know what way to go to say your self a buck possibly.
It also matters what the cost of the crank is so weigh it out.GET IT.:tongue3: :sad3:
