tranny cooler
unless you are running a little engine and trans combo with a real low stall( like a little put put street rod, ) i would run a good size tranny cooler(not one in the radiator) out in front of the radiator. those little frame rail coolers that look like a radiaror fin really cant do much cooling and they probably wont get much air flow through them, and they are usually close to the road surface(hot summer road surface). do the right thing and put in a good one(not 3/4 inch thick) but 1 1/2 inches thick if it is a street car and same if it is a drag car with any kind of stall. just my opinion. i did it like this on my street vega 406 sbc with turbo 350 and about a 3400 rpm stall. i used a 10x21x1 1/2 thick tranny cooler mounted in front of my radiator chevy art
