Is a 400M crank in a 351w the cheap way to build a 393 stroker?
I thought I read this somewhere,that the stock-car guys came up with this originally. Will a M series crank even fit a windsor block?

This is for my driver, stock 351w that needs a new seal/speedi sleeve on the front main bearing. I don't want to spend a lot of money on it, since that has all gone into the other truck I am building. But, if I have to yank the engine and pull the pan off, I could swap out the crank, and maybe even the rods in a jif while it's onthe engine stand.

If this will work..
