I ended up going with the Brodix RaceRight Oval ports in 270cc, also using a RPM Air Gap. I think any of Dart, AFR or Brodix you can't go wrong with. You might also check out Comp Cams Thumpr line of hydraulic roller cams.
Right now the motor is broken in but not in the car yet, but it has a nice sound on the engine stand, and Desktop Dyno puts it right in the 600 range in torque and hp. 500ft/lbs off idle  You can check out my build in my sig.
Whatever you go with you do want to match all your parts to the intended rpm range of your application you will make the most power that way. Look at the RPM ranges of different heads, intakes and cams to help make your selection.
Good luck, and let us know what you go with! |
