Numbers look pretty good. Is this with the same pulley combo as before the new motor? If so what was the boost difference?

yes, same pulleys, boost went from 10.5 to 12.6. the top rings on most of the pistons were calapsed. the new rings were different than the old rings with the same part number. apperently something was up with the other rings, the new rings were also coated with something. IDK, my engine builder said they were different.

New engine sounded good on the dyno, and it put down some kick a$$ numbers.
