How flexible do cooling lines need to be?
Building a '32 roadster from a kit, I'm about to start work on the tranny cooling lines. I'm running a 700r4 and the cooling connections on my radiator are at the bottom.
BowTieOverdrives.com has a good looking tranny cooler line kit, but I'm pretty sure I can bend some tubing, flare some ends, and make my own lines for cheaper. The question is, how flexible should they be?
I made sure that my fuel lines had a rubber connection between frame and engine to accomodate engine movement, and the BTO lines have stainless braided from radiator to hard line, but I've seen cars with hard line from tranny to radiator and heard no complaints from their owners.
I'll be running the lines close to the starter and the oil pan, right past the balancer. Since they are so close to the center line of the motor, they won't twist THAT much when the motor rocks, but they'll twist a little. So, will the naturaly flexibility of steel line (around the axis of the tube) safely accomodate the motor's movement for years, or should I go for the BTO kit?
