You need to have a crank that is internally balanced and a 1 piece rear main seal.

You can use a old 400 crank but generally it is not worth the effort unless you have some nice trick aftermarket crank. By the time you grind it undersize to fit the 350 mains and buy the rear main adapter you are at the cost of the basic aftermarket cranks meant for this purpose.

Maybe Karl Ellwein will pop in, he has a stout motor he built like this and I believe he discorages others from doing it the same way. Works but is not worth the effort.
