how to raise front end of car?

All correct, so it lowered and you put smaller tires on- backwards. Torsion bars too small/weak/not adjusted to begin with.

Hookers, etc will always scrape on the ground, that's why they are cheap.

Try this; with the car on the ground; measure to the floor, from the lower part of torsion bar, then lower ball joint. Factory is 1 1/78" difference.

You can raise it with the torsion bars, but alignment goes all over the place, sometimes can't be re-aligned correctly.

Go back to standard tires, and read up on low hanging headers.
