Breakkout,
just saw your post.. still got the Bravada?
did any mods yet? not trying to dissuade you from the lift,
but might insure before the lifting, you check around your block to
see if any of your tech friends have a SnapOn brick, as you migth need
to re-program ECM, as GM set the SmarTrak parameters to only within a certain ride height, and wheel size.. plenty of lifted S10 blazers, but i've never seen a Bravada on 35s.. i would imagine still do-able; but maybe start with the speed aspect first.. maybe not even a 350SBC, but a turbo on the 4.3 (like the Syclone and Typhoon).. after you start going faster in the AWD, you might decide you want a slightly lower stance..
good luck with your project.
