M8 cams
I'm not up on cams for M8s but I'm going to be doing them for a guy I work with after beating him up with my 103 this past weekend. I'm a bad influence on him. ;p
Anywho, he's wanting a torque curve similar to the S&S 570s, Andrew's 57Hs. That sort of torque curve. He's currently running Rineharts but ditching those for something better. Most likely some Rush Big Louis if they're available.

There are a ton of threads in the M8 section on cams, and there is a lot that goes with it. What tuner are you going with?
He can keep the Rineharts and put some Fuel Moto inserts in them, M8s need a little back pressure for bigger torque numbers.
Popular torque cams are RS468, S&S475, Woods 22x

RedShift and MaxCell are posting some pretty sweet #’s as of late. Do your research, those M8’s respond well to a cam swap.

Thanks. I'll look up the specs on some of these. He's not looking for torque cams really but more middle of the road so to speak. Why I mentioned the 570s. I brought up changing baffles in the Rineharts if anything decent fits without too much trouble since he could kick himself for the $$$ he spent on them. Without getting into an exhaust debate would it be a fair assumption to say the reason for the thought these need back pressure is because of the cams normally run in them? Reason I say that is he really likes my 3" Rush slip ons with 2 1/4" baffles but I think he would need to go with the 4" Big Louies.
Anything need special attention in there? I haven't been in one yet and I'll have a fsm but any tips would be appreciated. Helps me plan ahead and a few of my mechanically challenged friends own one now so I guess it's time to learn. I'll read up on some threads here.
He's got FMs tuner.

The 475s sound awesome and have a great idle that would really rock with the Big Louies and I think with the 2 1/4" baffles would be more than strong enough down low and really start to rock about 2800.
