The dyno sheet photo shown here are the power/torque figures in the room and not corrected. With 603 bhp in a very driveable package this is THE engine for that early model restoration, Hot Rod or weekend bracket race car. Imagine a 9 second Torana or VK Commodore on pump fuel and with no bonnet scoops. No valve lash to check between rounds either. Drive to the track drop the pipes, fit some slicks and go.This dyno run shows the results with a custom set of Gonzos Race pipes extactors. With a set of off the shelf Pacemaker 1 3/4" primary Tri-Y Commodore pipes the peak power was still an amazing 583 bhp @6000 rpm amd 540 ft.lbs torque @ 5000 rpm. Torque @ 2750 was a stump pulling 443 ft.lbs.
