*IMPORTANT INFORMATION! PLEASE READ!

All kits require balancing prior to assembly

 All of our rotating kits prices shown are non balanced. HMS can balance your rotating assembly
 before shipment, making it a direct drop in install.  All 4.6 modular motors are internally
balanced. The 3.75" stroker crank is considered a 5.0L (300cid with .020 over bore)...
see pic below for proper balancing. Balancing starts at $155.00. 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!
