i prefer to build a model, with an engine so i can put the kind of detail i like into the motor.
Most of the curbside kits i built, turned into lowriders, since most of my work on them was custom interior, opening doors, etc., in which i really had no want to do motor work.
5.4l Ford OHC motor (Lightning motor) w/ custom Intake, Custom Turbo setup, transplanted into a 93 Cobra.
(This motor is about 1/2 done)
