4 speed was not available in a Factory built car until 1962. You could buy one over the parts counter in 1961 (T10 BW) along with 3 duce set up and it was NHRA Legal.

There are, NO after market cranks readily available for the 390-427 I am aware of at this time. You can modify a 391 crank (expensive $1500) or have a Specialty Crank Company build you one (more expensive $2500 min) All aftermarket cranks are for Stroker combo's and not Legal for 390-427 OEM stroke application for S/SS.

A cast crank is not only lighter, it can handle most any S/SS application. I have been running 390's for over 20 years and have never had a problem with the strength of a cast 390 crank if done correctly.
