Yes, actually I've been thinking about something like that. And, there's a guy over at turbododge.com that was selling adapter plates to put a small block transmission behind a 2.4L - which is fairly plentiful. I was considering dropping one in my 69 Cuda to make it a good gas mileage car and maybe a daily driver.

You should be able to put one in with that adapter plate and make it a rear wheel drive car. The 2.4L will easily handle the weight of a rod and making it RWD will negate the issues of putting a FWD chassis in.
