CSK ,
i did have the mopar clutch hub , came with 5 blade as performance kit , but i cannot fit it now . I had maybe 3/8"clearance before . With new radiator and new side mounts it is barely 1/4"now .
Funny i have a 17"flex a lite fan i tried , but not real keen on that on the strip .
Its just one of those things , is it bad ? not totally . Could it be better , yes . Ideally i would like 190 freeway max
I could try the VP Stay Frosty complete coolant mix . I know some guys having good results with that .
I do quite a few highway miles and daily drive it .

thanks

Tex
