Do not use blocks on the front suspension! That's extremely dangerous and illegal in most states. There's too much forces from braking and steering on the front axle, blocks willintensify this and cause spring failure. I'm not really a fan of blocks on either end, but you can use them on the rear as there is less stressfull side loads like on the front. If you really want to lift it, look for an aftermarket kit w/ new springs with a deeper arch, or have a local spring shop re=arch the existing ones if they're still servicable.
Oh, and definetly check out 4 Wheel & Off Road, exellent mag if you're into the 4x4 thing, they even did a 'Bolt once as a project!
