what is 2 much ?

hi chris,
got a good one to run by you,if you will? right now i have the b&m (70266) trans cooler (11"x8"x1 1/2") and i`m running a 3800 conv. on a bblk. street/strip car. the tech at b&m said not enough to cool a trans on a street car with that conv. he said to go with the (70274) instead (11"x11"x1 1/2"). i`m figuring, go with another (70266) instead and use them both together. i have the room for both, one on each side of the radiator support frame behind the grill. does this sound crazy to you and is it too much? hope i didn`t put you to sleep with all this and thanks, gene
