i have an '07 police interceptor that i love dearly. i bought it back in 2010 when i was a taxi driver in philadelphia, have driven it up to alaska and back, all around this country. i've been experiencing engine problems for the past year or so (only 170k on the engine), and have just taken it out and put a used one with 90k in it. it was a cheaper option than all the labor necessary to take off the heads and inspect everything, and a much quicker process. i decided to pay the guy an extra $150 to keep the old engine so i can rebuild it myself.

all the best,
