Builder doesn't have a dyno, but his build program estimates the hp around 300 and torque at 425 and he's built a LOT of race engines based on info from that program. He hadn't ever built a high performance 6 and had to laugh when he finally idled it down from the 2,000 rpm breakin and it has a slight lope at 650 rpm.
I've waited a LONG time to have a vehicle to put this in.
