Lowest cost 400 stroker

I built a 523 stroker in 1980, waaaaaaaaaaaay before any of the stroker kits were available. I used a 440 crank welded up for a 4.375" stroke.
There's no way this would make sense these days with the off the shelf stuff available. But still very cool that you were doing this stuff back in the day! Hat's off to you!
