3.6 Pensatr Engine swap

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.

Pretty sure the stock 3.6 in my wife's WK2 is rated for 285hp not 300+. Either way I'd imagine it would be a great swap. Not sure how expensive though or how to deal with the electronics.

Its a great motor, but for 285 horses I'd just stroke the 4.0 and run 91..

Unless you listen to Cal.. A GM LS-based V8 swap makes much more sense.
