Not much to tell here. I'm running a basically stock rebuilt 289 with small chamber cast heads with a CompCams Nostalgia Plus Hyd Cam with matching rockers, springs, lifters & pushrods. I set it up this way because I planned to Run a 600 Holley Double Pumper. It could idle a little cleaner but it's a racecar, right? Cam Specs below.

My 331 in my GT40 had 10.2:1 compression, Comp Cams hydraulic roller cam (.600/.600 lift, 232/232 deg dur @ .050, and 112 LSA). It spit a little but we tuned most of it out. Ran great once you passed 2500 RPM

Question Do you have a fax machine around

Stentor I can mail you a copy of it. This is old info on this build and it was done in the 80's. It's about building a 600HP motor, we have 1/2 dozen builders here that are make 650 hp on street motors without the webers or Olbergs. Vacuum signal to the carbs at a steady rate is the most importnat thing and a good exhaust system with the right back pressure. Rick L.
