Hey guys I'm just about ready to install my new 463 in my '85 z28. I'm thinkin the whole cooling thing is gonna be a problem since im going from a 383 to the big block I dont think the aluminum radiator is gonna cool it. so whats ya'lls opinions, Will the 383's alum. 2 core cool it? Will I need to got to a 3 or a 4 core? Also I'm gonna have to swap from pull to push fans cause of space issues with the engine. Any help is greatly appriciated

 

the current radiator should be fine. with a properly working airdam and fans

 

I had a single electric fan on it before and if I stood on it hard it would run up on the temp. But that may have been from the single fan. I was lookin on e-bay at 2 3500cfm fans to put in front of the radiator. what you think
