hey an aluminum versus a 4-core dose a have a weight difference its probably the wheight difference of a a/c compressor or a smog pump, and people are deleting them from there system all the time for better ets so every little bit counts, plus they are better for disapating heat, the radiators on sale at summit right now, have a 15% more cooling capacity than factory 4-core models and its a single core design, coupled with an electric fan it can accomodate 350hp., but hey theres a cheaper way and that is what motivates some people, but if i have to invest the time and the money i want to do it right the first time when it comes to my stang.

 

i run a fan from a volvo and with my new radiator and 180* thermostat, my fan rarely even comes on but when it does, the temp drops immediately
