>>Hi Neil
>>Many thanks for the info and open invitation to ask your ear off.
>>I got my A&A scoop yesterday and have been busy trying to match rads 
to
>>it. When I phoned they said it was 9x24" but they had measured the
>>box--duh. Anyway it has led to a number of interesting discoveries.
>>--the heater cores used on GM trucks are now all alu (most have 
plastic
>>tanks)
>>--motorcycle rads are all alu and many of the larger Susuki bikes,
>>750-1100cc, rads are crossflow measuring ~8"x~17". Fits rather nicely
>>with my 8 1/2 x 17 1/2 scoop. I'm actually going to use two rads I 
think
>>I'll set them up in series feeding the rear one first In my case I'm
>>going to run alu lines on the inside of the cockpit to just aft of the
>>seatback at elbow height. It sounds odd but I sat with it today and it
>>works. Insulation will be an important item of course.
>>I'm still leaving the option of a heater core in the right cowl to use
>>as cabin heat or dump extra heat ( or to supplement oil cooling)
>>Wings are on, except for one flap I've left to make working on the
>>cooling easier, all electrics are up and running--getting close!
>>Will keep you posted
>>Don
