I just bought a Flex a lite 180 from Summit that is rated at 3300cfm.

It looks like a very nice, well built unit, but will require a little shroud modification/trim around the lower radiator outlet, other than that, it looks like it was made for my 22RE radiator.

The 180 dimensions are 17 1/2" x 21 1/2" x4" 3300 cfm
The 165 dimensions are 18.0" x 16.0" x 4 1/4" 2800cfm

If 1 elec fan doesn't do it, you could add a tranny cooler and if it still doesn't work add a fan to the cooler.

One other thing, Summit will beat any price you find on the net, so I saved a big chunk of money when I bought it.

If anyone is interested, I may post pictures when the install is done.

Take care.
