Cut up the shroud to provide airflow to the fans...

I plan to use these Spal rubber flaps to provide airflow bypass at "higher speeds", just figuring out numbers and placement...

For sealing the shroud to the radiator, with the weld beads and uneven surfaces between the core and the end tanks, I wanted a seal vs. just butting the bare shroud up to the uneven radiator. I found some aluminum square tube that I cut in half, to provide a resting channel for a seal.

I decided to give this "high temp silicone foam" seal a shot, good for 350*F, sourced from McMaster...

Resting height is about 1/2" including the C channel, and I'll compress that by around 1/8" once the shroud is assembled on the radiator...

Something like this once assembled and squished...

Started cutting and tack welding the C channel onto the shroud, but ran out of time. Not quite sure what I'm going to do around the clearance notches for the inlet and outlet.
