Dyno numbers are in. But they aren't the final numbers. Turns out that the dyno was used to ballpark the timing and jets and break-in the engine. After looking at the data it looks like the jets could go a couple sizes larger and less timing could be used. Seems the heads are so efficient that they want less timing. Find out something new every day. Final dyno tuning will be done on a chassis dyno.
Break-in numbers:
668 HP @ 6900 RPM, 532 Ft. Lbs. of torque - open headers.
10 HP and 10 Ft. Lbs. of torque loss through the mufflers. Talk about an efficient exhaust system.
