    Hotrod, where you been?
    I can tell you that blowers come in really early, around 2500 RPM. Most converter companys will tell you a 10" and specifically built for a blower or nitrous and i agree (bullit proof) Also you will probably need a throttle controller to keep from blowing the tires off. My suggestion would be 4,000/4,500.

    That thing looks real mean..... but where's the nitrous solenoids...lol

    Seriously though, give Chance Race Convertors a call. Marty Chance will tell you exactly what you need, whether you buy one of his or not.

    Oh no.... i saw low funds...and used parts. Be extra careful! That engine is gonna be brutal on every drivetrain part back. Should easily make 1400 hp with a mild tune.
