I bought the Woverine dual duration 270 cam from Tom Langdon for my 292. It's a very nice cam with a mild lumpy sound and great power through out the gears. Check you rear end ratio. If you're climbing hills, any gear below a 3:23 will feel like it bogs down on a hill climb. I use a 3:55 but I have a T-5 infront of it. Taller rear tires will also affect hill driving aspects.
Lots to think about, right?
