Torsion bar size

[70Barracuda]

I am thinking a 383 with aluminum intake, water pump housing and heads weighs like a SB?

I have the PST 1.03 bars. My 440 has Aluminium intake, heads, water pump, waterpump housing, and the battery in the trunk. I don't know if it weighs about the same as a SB front end, but it is significantly lighter than a stock BB front end. If I had to buy replacement bars I would go 1.1 or thereabouts.
