it used to be a four cylinder but was swaped with a 5.0L. the many things done to it are a stock motor with a vortex v3 supercharger kit running low boost om stock motor, t-5 trans built for over 400hp, fully built rear, and a bunch more. in the middle of building another one so if this does not go soon will start taking parts to put in the other one. if interested call or text me at 610-984-5437
