Would the 4.7 liter from my 1999 Jeep Grand Cherokee fit in an A body?
Me 3. At nearly 100,000 miles mine still runs great and figuring it's a heavy truck with the aerodynamics of a brick it gets pretty fair fuel mileage (17 in town, 21 hwy). That's a lot better mileage than my 93 5.2 Dakota got. My 4.7 has no problem at all lighting up the tires at a 20 mph punch and barks second gear. I've pulled a car hauler with a big Pontiac on it and it pulled good.
Back to the subject, would I put it in an A-body, absolutely not. Just as much work as putting in a gen 3 Hemi and you'd have far less power.
