diiulio,
We do have an IRS option in development. We have one on the road and another is being delivered later this month. We are waiting to make an official announcement on the IRS until we get a little more feedback. We expect to formally have the option available later in the month. The IRS will have a Ford 8.8 center section with custom axles. The one car on the road with the IRS has a 427 side oiler with 500+ HP. He had the car on the track last weekend and there were no problems with the IRS holding up. Feel free to call if you have any other questions.
