All Rotating Assemblies are balanced

  in house on our computer balancing machine by a professionally trained tech.
 All 4.6 modular motors are internally balanced. The 3.75" stroker crank is considered
a 5.0L (300cid with .020 over bore) All stock Romero 4.6L engines have a 6 bolt crank 
flange! Some 99-00 mustang GT engines were Windsor based...these do have a 8 bolt crank. 
 All of our forged cranks are 8 bolt flange.
When running a 8 bolt crank, do not forget about a new flywheel!
