I have a 1950 Chevy Deluxe that I'm planning on installing a 283 sbc and TH350 trans. I'll be ordering a replacement radiator with standard top and bottom tank, and cooler in bottom tank (lines spaced approx. 12" apart) What is everybody doing for trans cooler lines. Are there any pre-bent lines that might work? Or that are the best choice for starting
1966 Chevelle with TH-400 trans should be very close to correct length forward of the engine and oriented for bottom style tank radiator. Will be the same as TH-350 back at the transmission end. Th-350 trans didn't come out until 1968, by then cross flow radiators were the norm..
I've used repop for tri five chevrolet using a 350 turbo. 400 will have to be bent a bit as the trans cooler holes are just a little different. Then modify the radiator end to fit the radiator.
