Thanks for you help.

The fan hub needs to line up with the edge of the shroud, with the blades covered only halfway by the shroud for the best air movement. A fan blade ahead or behind the back of the shroud doesn't flow nearly as much air as one that's properly positioned.

However, I know for the cars that the 8's had a factory shroud, so you may want to try and find a factory small block shroud for your 283, if they exist for the trucks. | | | | | Joined: Dec 2011 Posts: 264 Shop Shark | | Shop Shark Joined: Dec 2011 Posts: 264 | I put a 350 in a styline and used the original type radiator with no problems at all. | | | | | Joined: Aug 2013 Posts: 568 Shop Shark | | Shop Shark Joined: Aug 2013 Posts: 568 | My 65 has a stock radiator and a v8. Get the shroud if you're going to use a mechanical fan. I have no shroud and a single electrical fan, never over heats. 383 ci. 180 degree thermostat. Fan is on a relay off the temp sensor.

I can explain it to you, I can't understand it for you.

The six cylinder & V8 radiators, were not the same in the '63 Chevy light-duty trucks. The standard six cylinder radiators, sat in the lower cradles on the lower flange of the radiator cross member, between the the frame rails, whereas the wider tanks of the standard radiators, in the V8-equipped trucks, sat on the top flange of the radiator cross member. In my opinion, since you are installing an era-correct 283 in your '63 Chevy truck, a factory-correct V8 Harrison 2-core, 3-core or 4-core radiator & corresponding fan shroud & shroud extensions, are appropriate.

If all you have is the six cylinder radiator then make sure you can flow plenty of air by it whether you use an electric fan or find a shroud to help pull the air through.
A 3 core radiator for a stock 283 is overkill even in the Texas heat providing air is moving across the radiator.
