If that is the build described in the June issue of Mopar Action, on a four wheel chassis dyno they got 380 whp at 4800 and 460 lb-ft. He says that translates to 475 hp and 565 tq at the flywheel. I need to find the previous four installments of the build.
@gzig5, Thanks for that update on the Ehrenberg build. I respect his work and was eagerly anticipating the outcome. I expected it might fall slightly short of the 500hp goal given the exhaust manifolds but that's an impressive result regardless.
