More.. To break it down- 58/60 MEL uses FE bell pattern. 61/65 LINC 430 uses a modified FE pattern (to allow engine fitment within new LINC frame rails). 66/68 LINC 462 uses the previous modified FE pattern and the newly released LINC SPECIFIC C6 pattern. The 460 engine block (1968/ ) had both the previous 462 LINC SPECIFIC bell pattern AND the FORD CORPORATE C6 bell pattern.
