You are apparently looking at older MHs. 454 had TBI from '89 or '90 and in '96 the Vortec with MPFI was introduced. Ford had MPFI in the 460 in '89. It is much easier to care for the EFI motors than the old carburetors. I have had Cs and As over the years and an older C is much more likely to leak in the cabover section. Delamination is a problem on older of both categories. That is bubbling or waves in the siding that comes from a water leak and is the wall coming apart. RUN if you see one like that. It is fatal. You aren't in CFB Petawawa by any chance?
