I doubt he will give you the specs...Great guy though, spoke to him at lenghs on the phone and decided to order a 108 myself. The guys at brown's saw it and ordered a couple for their trucks and for a customer. I've talked to many guys that have swapped over to his cams and the proof is in the drivers and their trucks. No one I have talked to would have any other cam now. I will update as soon as my truck is done. I had trouble spooling and cleaning up 240 hp injectors with another companies cam, using a 64mm over a S480 twins. I talked to another guy here that has an almost identical setup, he swapped in the 108 and said it spools his 64mm so fast that he wants to swap out to a 66mm on top...
