Big Block Suspension Question

67BBCuda said

In the very early stages of resto right now, putting new brakes in to get it road safe.

But in doing the brakes, the suspension might as well be changed. We plan on doing a 440 swap down the road. On a scale of "almost useless" to "absolutely necessary", where does changing the torsion bar suspension to a coil over conversion lie?

For information, it's a 67 Barracuda that will be almost exclusively street driven, with occasional track days.

Thanks in advance.

“almost useless”

From a suspension standpoint it’s completely unnecessary, you can get the torsion bar suspension to do whatever you want the coilovers to do. There are some minor pros/cons but it’s basically a wash IMHO.

The advantage to the coilover conversion is the rack and pinion steering, which some people prefer (but doesn’t make you any faster) and the header clearance. Not sure how frequently you pull your engine or headers, but you can install the headers with the torsion bars faster and cheaper than you can install a full on coilover conversion.

And you can fully rebuild and completely upgrade your torsion bar suspension for quite a bit less than a conversion.
