It should be making at least 550hp/600tq at the flywheel. One of our customers dyno'd one with 290cfm KRE heads from SD, a port matched RPM intake, q-jet and 4 tube headers, and made 552hp/604tq. He did the testing at a "Chevy" shop, and was told when he brought the engine in for testing to dump the dual plane intake and Q-jet, because it wasn't going to make any power. He said they were dialing 911 and running for the exit doors when they made the first pull!.....Cliff
