chassis dyno Roush 427R
Here is a chassis dyno of a Roush 427R crate engine, as installed in a Superformance. They have installed many of these 427R engines in cobra's, and this is the best output any of the 427R engines had made. They are rated by Roush at 550 HP and 535 torque at the flywheel. The engine was not run above 5800 rpm's where you would expect to see max HP, but the max torque is a good value.
I wanted to use this engine as a benchmark to compare my 427 SO engine to. Both cars running the same sidepipes.

Re-wiring dash / gauges '55 Chevy
Hot Rodded '55 chevy needed some TLC, as the wiring over the years got out of control, and none of the gauges worked.

Clutch MC and brake MC in reverse positions
This shows the clutch MC next to the steering shaft with the brake MC mounted behind it to the fender well, with the clutch MC activated by this odd bellcrank type arm that may be messing up the pedal ratio. Trying to sort out why my clutch is both super heavy pedal pressure AND has to go all the way to the floor to disengage. Anyone know if this is a standard shell valley setup? The other end is a hydraulic throw out bearing, looks like a Tilton.
