General Motors is once again proving that pushrod V8 engines still have a place for this world, thanks to the addition of direct fuel injection, and advanced combustion technology with its fifth-generation line of Small Block engines. But such innovation brings a new level of complexity to the table, and even Ken Lingenfelter, owner of Lingenfelter Performance Engineering, confesses that it might take some time for third-party tuning companies such as his to fully grasp the workings of the new family of GM V8 engines.
Lingenfelter also mentioned concern over the performance threshold of the LT1 motor. Where the family of GM LS engines were routinely capable of doubling their output and handling that power, the new LT engines may have a lower ceiling to work with. But his engineers also haven’t had a chance to really dissect the motor, either. That being the case, the verdict is still very much out for the LT1. But if a guy like Lingenfelter has something to be uncertain about, you can’t help but listen.
