What the CAM???

I did and it was worth it, but if I had to do it again I would change the head gasket to a .030 MLS while I was at it. When I did mine I pulled the rockers to reuse the stock pushrods and I was almost there. I ended up going back and changing the gasket and had the heads ported at Big Boyz while they were off. It ran fine with cams only but with a $299. port job it really screams.

If you want a cam that comes on in the mid to upper rpm range the Zippers Red Shift 575 is a good set. I just had these installed in my Fat Bob, got about 50 miles on them so far. The torque comes on real strong at about 3700 rpm and peaks at about 3900 rpm and starts to fall off at about 4200 rpm. The horse power is climbing the whole time and starts falling at 5600 rpm. It's fun when you want to pass someone, just drop a gear to get it into that rpm range and the thing turns into a rocket, hold on to those bars. I am really happy with my choice so far. Cool sounding lopey idle too. More valve train noise though. Any way good luck choosing a set of cams, lots to choose from.
