My Regal used to be a n/a V6 car but now has a SBC V8. However the Regal did not came with the shrouds in the grill to divert 100% of the air that travels through the grill to be forced through the radiator like GNs have. Would it be worth getting this kit to help improve engine cooling? http://www.gnsperformance.com/products/radkit.html BTW, I do have the proper V8 radiator and V8 fan shroud installed. thanks.
