That'll make a big difference.
When I did my 3 core radiator I had to either ditch the mechanical fan or find a different spacer. The fan interfered with the radiator.
I bought a cheap fan and relay on ebay. Every part in it died except the relay. The temp sensor died within about a 2 weeks. The fan died about 4 months later. When the fan died I stopped in Autozone and found a universal fan for about $60. Mounted it as a pusher fan and haven't had a problem since.
...plus it's hidden.
I made a radiator fill panel as well. Doesn't do anything other than cover up the front hole. Now you can't see much at all other than the radiator and the rheostat mounted to the side of it.
