Nothing major maybe a mild 4.7 in the Unlimited. I'd trade the wj in a minute for an Unlimited V8. I have a boat & camper so
the V6 just won't cut it for me. I remember the old 304 Renegade 3 speeds that could loft the front end over a beer can right off the showroom floor. Don't ask me how I know this and it is probably the reason you can't buy one now.
I sure do miss the old Renegades though. Maybe I'll write my congressman or Ralf Nader
