here's my plan for rigidity.
take the motor out, put it in a go kart, or something ugly and small, like a festiva.
follow a cobra driver home, steal his car, bring it to my garage. weld up tubular steel the length of the car. take the rear suspension out of the cobra, bolt it up to the contour subframe. yank the engine, and wiring. put it into teh contour, however it fits. balsa wood, elmers glue, welding steel in, pop cans, hockey sticks, whatever to make it fit. cut a massive hole in the hood where the ported eaton will stick out, for extra cool points.
bring the cobra back, pulled by the festiva, with a sign that says thanks for the drivetrain, here's a festiva.
spank everyone down on the strip next weekend. lol!
