Coming from a guy who has tried most of the popular cams, I liked the S&S 465 over all of them. Like you, I liked the power delivery of the sock over all of the popular cams with the exception being the 465.
It's not the power delivery I prefer over a cammed bike it's the linear throttle feel from idle.This 'bogging' or 'soft' throttle coming off idle isn't for me.
My main objectives with a cam choice(if possibke)
Linear throttle feel throughout rpm
More power(a given)
A lope/chop.
I also don't want the bike to 'want to be a gear lower' than stock cruising.The 475 wanted 2nd when the stock 114 was happy with 3rd.
The 475 wanted 3rd when the stock/stage 1 was happy with 4th and so on.
Sorry I misread your post...The 475 has a pretty late exhaust valve closing point, making it extra picky with the pipe. The 465 is nothing like that and should work fine, along with the others you mentioned, as long as it's tuned well
Agreed. There are a couple of the bolt-in cams that have a wonky dip in the low end when used with the wrong exhaust. My Rinehart system was no exception with the RS468
I picked a more common, and easier to tune exhaust system this time around with my cam change.
Finding the right guy to tune around an exhaust issue is tough.
I am using a local tuner for the first time, hoping he can dyno tune a Woods 408X from a canned map from Jamie. I am nervous!
For the OP; I am excited to hear your impressions of the 480MT! I have heard good things
