Destroked Small Block?

Certainly one of the most interesting discussions on the forum in a long time. So many of you guys are straight up encyclopedic. :cool:

As @autoxcuda and others have pointed out, this is not the best dollar:performance approach but the thing that occurs to me in an era of 32v /460 crank hp 5.0L, 11 second 1/4 mile times in the basic 2018 stock Mustang GT, trying something totally different with old tech is the best way to keep our old cars fun and interesting. The idea of de-stroking a small block, coming up with a valvetrain, head and rotating assembly that can use/handle, make power at 7k+, sounds like the bee's knees to me. :cool:

I recall that piston speeds in a performance gasoline motor are typically 60mph at redline or so...is that right? Are there motors out there which can handle piston speeds much higher than that? At what point does energy required for accelerating the piston back and forth begin to become counter productive?
