Finally got the beast tuned yesterday. She made a respectable 620 rwhp and 596 rwtq, but need to change the diafram on the fuel regulator from 6:1 to 8:1 cause she was running too lean after 5250 rpm and we had to pull some timing off. Which means she will need to be retuned again and advance the timing. Good news is that should be good for at least another 10-15 rwhp and 20-25 rwtq based on some previous runs without any timing pulled. :rock:
This was with the stock exhaust manifolds (That for you Mikey
