just read all 1300+ posts. Frank- thats great work man. I had a 1998 Pontiac Grandprix SE that had the 3100 in it back in highschool. One summer i saved up enough to grab an entire front subframe, eng trans, etc from a 2000 GTP and swapped it over, modded before installed. That car was an absolute blast, and eventually became the oh so deep money pit. I eventually blew the motor after putting some nitrous on it at the strip. Miss that thing. congrats.
