Do not think that the existing HD 266 cam is a weakling.
It marks hp/torque damn near the same, as the formidable S&S .640.
A T-Man 662-2, would be interesting, though, set at 11.0 cr.

I'm sure many owners will be happy to try their new toy bone stock! There are plenty of dyno sheets in the various 120R threads in Touring. Some of us would love to be able to join them.....

When I installed a 120R in my 2012 SG I thought about replacing the cams; but I read Hillside's post on another forum on how the 266's are a good cam and opted not to. Here's the dyno (58mm TB, 5.3 inj & Dragula 2/1 3.05 baffles). There's probably a bit more I can get out of the engine, but I'm satisfied for now.

aviscomi those numbers are a bit low in my opinion considering they are STD... my stage 4 103 makes 122/121 STD
ive attached my dyno sheet with SAE numbers

this thread is an attempt to get all the 120r numbers in one thread so poeple can show there different combos and results...
