hey grumpy, i have a question. Can oil/trans coolers be too big? I have a 350 with a TH350 auto with 3.90 rear gears in my Z, and i was wondering if it would be ok to use -8AN (1/2" tube) with it, and the cooler i have laying around is pretty big. The trans is upgraded, with a shift kit/full manual valvebody, and i have a high flow oil pump. And i do drive hard on the weekends....
