s10 ride height for setting pinion angle

i was wondering if anyone knew how far typically the frame rode off the ground for normal driving height for an s10. i built my own 4 link with no adjusters(kinda like the suicide doors one) and need to know what to set my pinion angle at, and what normal ride height may be. i am running stock rims and tires for now and will probably use 18'S in the future. keep the sawzalls buzzin and the sparks flyin!!!
