I went back and looked to refresh my memory and Aragona's motor was making 534lbft at 3300 and 420hp at 5000 so it sounds like the new maxed out HO made in excess of 535lb.ft. of torque and 421hp? Would love to see the dyno sheet or know the numbers at various rpm to see how the whole curve looks. I'm continually amazed by how much power these relatively stock motors are putting out and at factory type rpm levels, congrats to you guys for pushing the limits on both these motors.
