My problem with the crank pulley was that the D16Z6 crank pulley is longer and the motor sits a little closer to my fender than the D15B2 did. It made it where I couldn't get a rachet of ANY KINDA on to the crank pulley from the top and you can't get ANY leverave from the bottom.

Good thing I had my "BIG DUKE ( named after the baddest BIG BLOCK CHEVY HEADS ). Its a HUGE 3/4 impact. I have to take my presure regultor outta my compressor hose to move it, but it busts huge nuts/bolts loose easily.

 

Yea, somtimes you have to drop the front left engine mount some to get more room.
