I'm using mahle pistons and have 10:5.1 compression , a similar build to Swinger and am getting 412 HP 398 torque with lunati # 60403 cam

268/276 226/234 .494/513 @110 degree

.

I was actualy considering that cam. Do you like it? I thought it sounded good because my x heads are lacking flow on the exhaust side so the extra lift and duration may help the engine breathe a little better.
