I'm running the 23-712-9 Comp Cams Hydraulic roller cam, XR286HR10 in my 505 engine. It is 236/242 duration @ 0.050 and drives fine doing 50 MPH @ 1,500 RPM in 5th gear (Legend Gear & Transmission 700 transmission.)
Engine is about 10.3:1 compression, Mild ported stealth heads, 17cc dished pistons, 1-7/8" TTI headers with 2.5" dual exhaust with X-Pipe. Originally a Performer RPM intake, but now Edelbrock XT EFI intake and FAST 2.0 EFI controller.
