You don't hear much about the old macks because they hardly ever break LOL
Go with 1990-1997 they were hands down the best engines mack ever made. Basically an upgraded E-6. Shares the same 4.875 bore as the E-6 and but a half inch longer stroke (6.5in). Beefier bottom end with buttress bolts in the side of the block to keep the crank from twisting for added durability. Stupid simple design. A bosch P7100 with an electronic gov housing (can be converted back to full mech) and variable timing to satisfy the EPA. All came with piston squirters no matter the HP rating. They can be turned into fire breathers. A few have hit over 700hp on Antrims dyno that are daily drivers.
The E-7 E-tech 98-03 is ok nothing special. Im not a fan of em at all. Macks 1st fully electronic engine. Unit pumps ran off the cam (which they did not beef up at all and ran into a ton of cam problems, broken unit pump springs etc) they don't even sound like a mack. The valvetrain on the old E-7 is way beefier, made to last.

80k with a flat is no different than with a box . You might want a longer wheel base and a mid roof sleeper.
The truck your looking at is heavy and probably had a hard life.650cat425, blairandgretchen, God prefers Diesels and 2 others Thank this. -
