I have no doubt that it is off-center to clear the steering rack. That is just about as much engine as will fit in that tiny little engine bay, which is why I cut the hole and why the next step will be stroking it. The plus side is, at her size she goes like a gazelle with its @ss on fire with just that hopped-up 302; I'm figuring a dual-quad 347 oughta launch her right off the planet. (For my next trick: a Hemi Gremlin.)

I'll knock up some shineage to put in the extra space; build a Flux Capacitor or somesuch.
