Are /6 torsion bars the same as 318?

This is a suspension question. Welcome aboard.

You can use the /6 bars. The T bars control up and down movement, shock dampen the movement. Stock 318 bars are thicker for more control or less of a bounce in the car. I run /6 bars in my '71 Duster, B block 400. It's more set up as a heavy street hitter. If it was a driver, I would use at least the big block bars that came stock. If I was carving corners, I'd just go to the thickest bars possible.
