    Quality difference in engines ?

    I own a 1991 Fleetwood with a 4.9L V8, I was thinking about getting a 1990 Deville with a 4.5L, is there a quality difference between the two engines?

    A quality difference? No. The '90 4.5 is the only year the 4.5 was port injected. Other than displacement, it's pretty much the same engine as the 4.9.

    Re: quality difference in engines

    "Quality" - No. Performance, power, application, parts availability, modification possibilities - yes (as in every other engine type/brand/size in existence.)

    "Quality" is twofold: It's an overall design function and that depends on the execution by the men and women who bolt the things together day and night throughout the year.

    ANY engine of ANY make in ANY year run can be bulletproof, average or Kleenex - one slight assembly mistake, one out-of-spec part, one slip of a CNC machine, bad threads, a million other possibilities and you have problems. It's the same today as it was in 1965 and in 1935. NO automobile has NO skeletons in its closet.

    Ever pick up a package of Oreo cookies or NutterButters and come across one where the cookie(s) are upside down or have no filling in between ??? Welcome to mass production. How about at the hardware store - a 9/16" SAE nut with no threads cut ??? Simplistic - yes ........... but the end result is less than perfection.
