Re: Eagle 4" 8BA Crank?
Most of the "Y" block cranks were Shelll molded. Some of the Ford 53 cranks were also shell molded. The look like a forged crank and are made from Marninsite iron with Magnesium and cast iron. Thes cranks don't have the brakaway area like the cast crank which as a group of four.A sad note the Ford industral rebuilding plant on Patterson NY didn't rebuld Mecury engines and when a 4" crank was found in a block it was scraped. The did the rebuilding for Sears and others. Boy that waz along time ago
