Original unmolested 400 Chrysler prototype spintron dyno engine. Unknown bore/stroke cubic inches pistons, comp ratio; camshaft specs unknown. It has a 3/4 or 1 inch head and intake spacers. 213 heads with hp valve springs. Motor taken out of Chrysler stock at the Trenton Michigan plant(?). With a 440(?) crank and 3/4 head/intake manifold spacers this motor might be Chrysler's first 500 cubic inch passenger car engine... that never made it to production or not.
