Mine is a 93 and have the e7 350 v mack turned up with high flow injectors. Parts not to bad for the motor in price. My friend has a v8 and parts are NOT cheap for a V8. Also find a parts truck. Mack does not have a lot of parts for a MH. I am looking for one just for a parts source. I lucked out on mine. Mine was the last year and mine was ordered by company that hauled pre cast cement forms. I am the second owner and truck has 430227 miles on it and 50000 on in frame. New rubber, brakes, drums, oil, and hub seals. My interior is mint. Eaton 40k rears 3:90 on reyco spring eaton 9sp air ride cab. I have all the maintence records and even the original build sheets. I paid 12,500 for mine. I hope this helps you out with a idea of what to do.
