Hello. Does anyone have experience with the Lingenfelter 350 engine upgrade. Based on the info I recieved the cam specs seem to be quite mild. In addition the upgrades do not require headers. Is their system worth doing. I have also recieved a quote from Livernois on a stage 2 setup. I really like that Lingenfelter offers some type of warranty on their work. Does anyone have any input. Also I cannot find any video of the Lingenfelter kit on an F-body. I want to hear how it sounds with their GT11 cam/ no headers. Thanks in advance
