I thought some of you might be interested in some frame mods I made to the Old Iron Regal to achieve some great 60 foot times. All the horsepower in the world doesn't matter if you can't apply it to the launch pad. We consistently achieve 60" times of 1.41, with a best of 1.38. Getting 3850 lbs on 10.5" tires to launch like this has taken me years to achieve. Along with the frame mods. shown in the in the attachments I have also boxed the side rails, narrowed the frame rails over the rear end housing and moved the instant center forward center so the car has a better anti-squat capabilities.
