Hi Michael,

I did option 1 about 18 months ago, and it is a great solution.  No
problem with the fan rubbing.  See, its not a thicker core per se (well,
maybe it is a little thicker -- I didn't measure) -- its that the core has
three rows of tubes for the coolant to run down and be cooled vs. the
stock 2 rows.  Basically, more surface area per volume of coolant to keep
it cool.

Even stuck in traffic in 115 degree Texas heat I wouldn't even approach
the 1/2 mark with the 71 degree thremostat (modified engine).  On the
track, however (say Heartland Park in 100 degree Kansas heat), I would get
up to about 3/4 -- time for an oil cooler :=).

If your fan is really close to your radiator right now, I'd check your
motor mounts....

Good luck!
