The biggest problem is finding a cam core to run a turbo grind. Lsm is willing to build one but is pricey. Comp cams said there price was $3000.00 for 1 cam core are $3000.00 for 3 cores. Then I find ought that lsm makes comps custom cores. There are no cores that can go anything over 112 lobe separation. James at Bullitt cams said he is willing to do a custom core, you might talk to him if you are thinking of going this route. If you find anything different I would like to know. Iam talking about roller cams. Good luck.
