    I recently replaced the stock 4.0 with a 4.7 stroker. I also replaced the injectors with 24 lb injectors. It will crank and idle but when I push the gas it runs raggedly. The motor is a crate from Titan. I need help!!!!!

    Welcome to the site! Have you talked with Titan to see what solutions they may have?

    Welcome to the forum. It's a crate motor and it'd not running under throttle. I'm subbed. Definitely keep us posted. I'm sure it will work out for ya.

    Raggedly can mean many things. Cam sensor, crank sensor, too much fuel, not enough fuel, disconnected or damaged vacuume line especially to the distributor. Timing not set correctly. I like Chris's idea and call Titan. They have a responsibility to help you.
