My buddy has one on his 86GT. 8.5 compression 327, ported Edlebrock Performer heads, ported Holley Systemax lower intake, Erson blower cam, Kenne Bell 2200, 9lb pulley, made 41X rwhp and 46X rwtq on a load bearing dyno. It's his daily driver. Added a water injection system to keep intake temps down. We both ran our cars at California Speedway in March. It was an open track event. 2.8 mile course, 4-20 minute sessions. So probably about 65 miles of WOT and not a single problem with his car (or mine!)
