I've had my 89 F150 5.0 for 10 years this month, and I tell you what, there ain't nothing like the old trucks, all of the old Ford, Chevys and Dodges were mint back then
You have a million mile work horse son!! KEEP IT, CHIP IT, BIGGER TURBO, 22IN RIMS AND SEND IT!!!! YEEEHAAAWWWW BROTHER!! ID LOVE TO HAVE THAT!! My 7.3 6 speed has 240,000 and she's still going strong. I just had to put a used trans in it and she's back to cruisin down the road. If your going to sell it don't ask less than 30K in my opinion
