Street Port 331 Program on the way!
With the success of my 331 Race Port Program I still get contacted about doing a milder Version. Well the time has come! This program is designed around a Hot Street setup or for Blown applications and accepts a 2.125 Intake Valve. With this valve size it has achieved flow rates of 320 cfm @ .500, 345 cfm @ .600, and 360cfm @ .700 lift. This is a scaled down version of my 331 Iron Race Program and could be used for a smaller cubic inch Race Effort (example Drag or Bonneville). This program is pretty versatile to be used in many applications solely because of the valve size used and the great design of the 331 head. Finishing up the final touches now and will soon be released!
