Apparently, the cast iron 216 pistons did not have offset wrist pins, while the "split skirt" aluminum pistons did have. Ford used aluminum pistons with offset pins as early as 1932 in their 85 HP V-8. The 235's and 265's with aluminum pistons used offset pins and cam-ground piston skirts to allow closer tolerances and quieter engine operation.
