[quote=dthemi]The predator made for hemi blocks is a better place to start. The wedge requires a removable plug in the intake port. Seriously limiting what you can do with the head. Also the 600 head isn't as good. A nice head for sure, but it is what it is. You can exceed indy's claims for power if you're willing to spend what it takes to do it. As soon as i can get another +.500 deck block Ill be building a 1400hp na predator.
