The new driveline arrives! Here's the initial fitting of the GTO's new L92 V8, which started its life powering a 2007GMC Yukon Denali. Here you can see the Street & Performance engine mounts and oil pan used to fit the engine in the GTO's bay. We modifief a pair of small-block Chevy frame stands to hold the engine. Also shown is the originally planned transmission... the GM6L80E electronic six-speed automatic. Soon after our test fits shown here, we elected to use the 4L65E 4-speed automatic from Bowler Performance Transmissions and a controller from TCI instead. Not only would the 4-speed fit better, but it was also tunable to our application. At the time these pics were taken, the controller on the 6L80 had not yet been cracked.
