Need some ft/lbs examples 292

[cerial]

Right, now I have a 76 292 stock internals with a 390, Offenhauser, stove bolt headers, 2.5 true duals that run open till behind the cab where they feed into dual 2"in/out porters then a 90 to dual open flowing turbo mufflers to keep it quiet.

I am trying to get a idea what kind of torque I am producing. I am picking up a 72 292 with around 60k today with the intention of doing that same bolt on's (with hei) to it that are on my 76.

I am hoping that the current upgrades on the 76 put me around 330+ ft/lbs.
If someone can chime in that has some kind of proven numbers that would really be helpful.
