I'm making some progress on construction. First things first--figure out how to place the powerplant. The mounting system needs to be robust 'cause if the car stops suddenly (like into a bridge abutment or an oncoming Escalade) I don't want the engine joining me in the cockpit. Ditto getting rear ended. So I'm putting the powerplant in a cradle made of 2" square mild steel tubing that wraps around the engine and will butt up against another 2" square tube at the back of the cockpit.
Step one was to make a powerplant simulator out of scrap metal. I bolted sleeves and plates to the engine mount and suspension attachment points on a Metro chassis, welded them together with bits of tubing, and ta dah! A thingie I could remove and measure without breaking my back or getting all greasy.
