I'm in the process of a 455 (Upgrade) from a 350 Rocket. While I know this has been done successfully many times, I have a couple questions for someone who's already been through it. The 455 I bought came with a cooling fan with a clutch configuration. Not sure if it matters but it was an A/C car. I'm in the process of removing my alt. and PS brackets and noticed that the 350 (Non A/C) car has a fixed or (No Fan Clutch) configuration. My questions are these.
1. Which one is better for a daily driver - clutch or no clutch?
2. Will there be clearance issues with my shroud if I use the clutch fan?
3. Will there be much if any power loss if I use the fixed fan?
4. The fixed fan appears to be smaller than the clutch fan - Will this be adequate in keeping the 455 cool?

Thanks ahead for your responses. I greatly appreaciate your help!
