I am sorry to see some valuable experienced folks drop out but I am still sitting in my garage looking at parts in considerable frustration. The topic here is that I have a 700R4 installed in my Brookville Model A frame and just finished installing a battery box in a somewhat unusual position on the back of the horizontal bend around the back of the pumpkin. This frees up the entire right side frame rail for some other stuff. In particular I have looked at every catalog I can find to look at transmission coolers since my '29 radiator does not have a trans cooler. In addition Henry Rifle sent me a small cooler which may be too small since he went to a larger one. The problem is the coolers with fragile aluminum fins are likely to get bent up from flying rocks on a gravel road and if I mount it on the right frame rail it will be right above the exhaust pipe, not exactly a cool place for heat exchange. I favor the plate-style coolers for ruggedness rather than the fin type but everwhere along the right frame rail there will be heat from the exhaust system. Another problem is that I would think it would be a good idea to put the cooler into the air stream under the car, but almost all the coolers I have looked at would be mounted to the frame flat against the frame and sideways to the air flow? All of this is made worse if I use turbo offset mufflers. A while back Tech1 suggested using cylindrical glass pack mufflers mounted straight thru but with the muffler reversed to use the interior louvers backwards for more sound deadening. Small diameter non-offset mufflers might give more separation between a cooler and a hot muffler but even so it is tight under there! Any suggestions?
