Ive owned 3 of them in various olds and pontiacs (pre Z days , forgive me) I have to say that the headgasket is the weak point in the motor , also in FWD configuration is one of the few IMPOSSIBLE things to do while the motor is in the car. might be a little tricky to get 18psi on it stock since it should have 10.0:1 compression I always wanted to put that motor into a fiero or chevy sprint or geo metro it is a good motor though , and pulls hard for being from GM in the late 80's...... good luck , that is a killer price for the motor later!
