How practical would it be to turn down one of the modern steel cranks to fit the small journal blocks? You could make a 389+ out of a 370, stroke a 347 at least 20 cubes too.
The 287 & 316 ports are just too small get very serious with, unless you were to use 370-389 heads & manifolds.
Sure, you could just use a 59-60 389 block & crank but that would be way to simple. Unless you were building a 421.
Curious about the potential here.
And would you recommend a morse chain??
