I've got a project in mind and I want a really small bore Ford small block for it. I'm wondering if on a 302 block I can get Scat to custom grind a short stroke crank, and with the right piston combo, get a roughly 4L displacement for a screaming little smallblock for a custom, ultralight, non street legal road racer.
All the above seems like it will work, not hard just $, but where I run into question marks is with the engineering of it, mainly the now very short stroke ~4" bores. How is having a stroke much shorter than your bore diameter going to affect the engine? Valve lift will be lower, or faster, but the amount of volume to move is lower as well by 20%. What I'm after here is a top end power band, low end torque is going to be non-existant, I'm aware. Just wouldn't mind hearing from people who know a lot more than I do on the subject.
