i have an 89 xj with a 4.0 and it has 240k on it , its time for a new engine. i want to swap to a newer much lower mileage HO engine. i want to have it professionaly done so there is a waranty. they tell me it cannot be done. or it can be done with my old intake and distributor. I want to have the newer HO engine AND the HO intake manifold instaled into my jeep. i also do not want the breather problems. what all needs to be done? or is the combination of the high output and the old intake a good matchup?
