Let's talk 318/349/390 strokers.

If I remember right that makes a 349 stroker, and a 390 stroker is a 4.00" crank. I think I read somewhere that the magnum mains are the same so you can run a 360 magnum crank in a 318 magnum block. And yes people have turned down 360 mains for a 318 LA, that part is possible.

Someone with more info will chime in. :)
