Crank your torsion bars up or get a taller tire, those are your options.
Well, you do have a 3rd option....... Move the engine higher in the chassis, this will require significant modification.
Which brings you back to...... Crank your torsion bars up or get a taller tire.
If your 4" wheel is a problem, get a wider wheel.
You are starting to make excuses. Tires are available that would put you closer to 26".
26" tire + a little lift from the torsion bars should get you where you need to be.
And RustyRatRod is right, 60s and early 70s cars stood a bit tall.
