SPECIAL NOTICE:  This Edelbrock part has received an Executive Order number (E.O. #) from 

the California Air Resources Board (C.A.R.B.) making it legal for street use on pollution-controlled 

motor vehicles in all 50 states.  To assist you with emissions equipment certification, we have 

included a silver fan shroud decal to help testing personnel verify that this part is a legal 

replacement part on the vehicle for which it is cataloged.  The adhesive-backed decal should be 

affixed to your fan shroud next to the existing emission and engine specification decal.  Do not 

cover your original equipment specification decal with the Edelbrock fan shroud decal. 

 

WARNING:  The use of “Thermal Wrap” or any aftermarket coating process will void the 

warranty on your Pro-Flo header.  Those products can cause excessive heat and moisture build up 

resulting in corrosion and early failure of the system.

2. Raise vehicle and support with jackstand. 

3. The use of penetrating oil when removing and the use of anti-seize compound when 

installing nuts and bolts will prevent the possibility of broken or stripped nuts and bolts.
