I'm going to drive this truck on the road but not every day.

Dan Houlton is running the stock first gen radiator (approx 400 sq in.) with his sc setup/al. shroud/taurus fan so I am using that as a baseline. I figure mine will need similiar cooling capability.

So this rad I picked out is 334 sq inches versus 400, BUT it is aluminum, BUT it is only single row and the Isuzu one is dual. I wonder if there are any graphs out there that show what size rad you need based on motor size, or hp, etc.

The thing about the tall radiators and moving the rad forward is you have problems making the hood close since you lose an inch or so of height as you move an inch forward with the hood edge. So to compensate you push the rad down to make the hood clear. But then the bottom of the rad is in front of your frame and blocks you from running a winch...

I was even thinking about tilting the rad forward on the top for intake clearance and back on the bottom incase I run a winch later.
