7000 RPM small block

Well, brackets are not easy to run week in and out. It's a little overkill. But, you want a package that you can dial in, and forget. Maybe adjust valves, and jet from your weather records. Otherwise, leave the hood shut and concentrate on other things. So, you should over build a litttle IMO, and then have the security to concentrate on racing. You can spend a little more, and you dont have to worry about exotic rockers breaking, or checking aluminum rods every season. Just race it.
