There is a potential problem with just using dyno charts to select cams for a street bike. Sometimes the cams that move the power to the left and still make great top end power have square lobes.

Best of luck with your build. I went to Johnson Engine Technology for my 88 incher [johnsonenginetechnology.com] where everything was done 'in-house'; the case boring, the heads, WEGO, ignition set-up and final dyno tuning. I am more than satisfied with the increase in cubic inches.
As a comparison to the Zippers 'torque v. horsepower' charts, posted earlier in this thread, my bike makes 107/107. I wanted my torque to come on quickly and it does. I'm above 90 ft.lbs. from 2800 RPM to 6250 and 100 ft.lbs. + from 3250 to 5250.
It's lovely to simply crank the throttle for a bit of air time: a cafe racer that races.
Have fun.

Well here is an update if anyone is still track this thread.
- Engine was shipped from Colonial HD 17 April to Zippers.
- Engine cams complete, working on heads now....so maybe another week before shipped.
I gave the Harley dealer my bike back in March and its been 2 months and still haven't seen much. The bike is just a frame right now.
I did spend a lot on additional accessories.
-RSD Clip ons
-LED Head Lamp in Black
-RSD Speedo relocator
-Front spoiler
-Badlander seat
Is this a normal waiting period on a turn around for such work???? I should note that I paid the shop up front so it's not a money problem.

My bike was at Zippers for almost 2 weeks getting some bugs worked out with the ThunderMax system, great group of guys and they really know what they are doing your motor is in good hands my man. Zippers HQ is only about 30 min from my house.

I don't think Zippers has his bike. Pretty sure his dealer is the one putting it togther.

Got the bike back today! And looks as good as it sounds! Colonial HD techs limited my rpm to 4500 so I don't destroy it the first 500 miles. Even at 4500 I'm doing 90 ft/lbs torque. So I'll just have to ride it for the next week or 2. I'll open it up when that time comes and report back

4500 rpm sounds way to high for break in. I wouldn't turn it over 3400 myself.
