Lowest cost 400 stroker

Right. What displacement would you recommend?
Well, I must admit, if I were building from scratch and buying the crank ready cut, I guess I would build the largest kyoob motor my budget could stand. That said, there's been a LOT of good talked about with the 470. Also the 499/500.

Also of note though, is "where" the power level cutoff is for a stock block. Isn't it somewhere just north of 650? I honestly cannot remember. I think whatever I chose, would certainly keep that number in mind, "whatever" it is. Because the more motor you opt for, the easier it will be to eclipse that number.

I don't know if any of that made sense. I've been up for over 24 hours.
