48 degree r3 block
hmm.... guess were not posting picts from photobucket for some reason. sheet started at 6200 rpm torque was at 491 to 510 at 7400 before it started to tail off. HP was 580 and peaked at 764 @ 8000. There was also another pull they did with different headers and 2 degrees more timing (37-38) and it peaked at 750.
