School me on torsion bars

[Skytrooper]

I saw something the other day that piqued my interest. I had never heard this before, so I bring it to the braintrust.

I saw an ad for mopar torsion bars. The ad stated...I believe..that the seller had a pair of torsion bars for a 318.

My question is, knowing that engines have different weights, do torsion bars need to match the engine due to weight or some other physical reason ?

Color me curious...

good question , I have never had a problem with torsion bars in a 318 car that I put a 440 into.

Torsion bars are... SPRINGS... so to speak. They have different sizes/rates for particular applications. You can have 6-cyl bars in a hemi car with applicable shocks to obtain the weight transfer, if you so choose. Basically, you can have any torsion bar you want, depends on what your preferences are, mainly soft/hard ride for street use.

I just want to second reading Andy Finkbeiner's "Torsion Bar Tango" article as recommended by moes above. This article gives a great introduction to torsion bars and their operation. Cheers!

I suspect your small block torsion bars will handle a big block but will have a bit more springy front end vs running the heavier big block bars designed to carry the added weight.
