Anyone swap a newer 3.6 penstar into an MJ or XJ. I'm doing some research for a possible swap to run Jeepspeed. Looking for anyone or information on a standalone swap for racing. With the new 3.6 putting out 300+ hp and lighter then a 4.0 seems like a logical choice. At least on the surface. I'm sure the mpg and running pump fuel would be added plus. 110 octane at $12 a gallon at 3mpg is way expensive.
