I dyno'd my 12a and got 122hp and 89 ft/lbs torque and 13 AFR. I have the following mods...

Full RB twin silencer exhaust
RB Holley 465 carb and intake
Stock Port.

I guess I was expecting to be somewhere around 150, do you think something is wrong?

 

122 hp at the wheels is pretty close to 150 hp at the flywheel. 122 hp at the wheels for thoughs modifications is pretty good id say

 

Good point, thanks.
