    1966 American Cars: Engine Weight

    Here are some interesting specs from Car Life magazine, May 1966.

    1966 Specifications. Included are the engine weights of American cars. Some are listed without the flywheel, so those will be noted below...

    ------ 361 V-8---------------- 640
    ------ 383 V-8---------------- 650
    ------ 426-Hemi--------------- 725

    --------- 327 V-8------------- 610
    --------- 396 V-8------------- 687
    --------- 427 V-8------------- 700

    Oldsmobile 330 V-8------------ 570
    ---------- 400 V-8 4-bbl------ 610 (no flywheel)
    ---------- 425 V-8 2-bbl------ 620 (no flywheel)
    ---------- 425 V-8 4-bbl------ 630 (no flywheel)

    Pontiac 230 6-cyl 2-bbl-------- 490
    ------- 230 6-cyl 4-bbl-------- 500
    ------- 326 V-8--------------- 600 (no flywheel)
    ------- 389 V-8--------------- 675
    ------- 421 V-8--------------- 685

    Ford 170 6-cyl---------------- 356
    ---- 200 6-cyl---------------- 380
    ---- 240 6-cyl---------------- 450
    ---- 289 V-8----------------- 485
    ---- 352 V-8----------------- 647

    ---- 410 V-8----------------- 670
    ---- 427 V-8----------------- 670
    ---- 428 V-8----------------- 680
    ---- 462 V-8----------------- 735

    It looks like the Lincoln 462-cu-in is the heaviest of the listed engines at 735 lbs with the Mopar 426-Hemi close behind at 725 lbs.

    Though it probably is completely irrelevant as an engine at some point must be attached to a car, did any of these engines make numerically either more power or torque (in hp/lbft) than their numerical weight (in lbs)?

    Seeing the weight figures I'd say no.

    Yeah, I don't think so, either.

    Horsepower per cubic inch was a common figure given. Although I think lbs/hp is a more useful figure.

    And gross power ratings?

    Maybe.

    What ancillaries are included in the weight ?
    It's always a difficult comparison as when do you include carburation and when fuel injection ? Turbos and superchargers ? Headers ? water pumps ? oil filters ? starters ? alternators ?
    Some of these are remote on some engines and built-in on others.
    So normally it's without "ancillaries" but without the turbos the Nissan is a pretty weak engine
    Does the article touch on that Fleet ? ie if an engine power is listed with supercharger then is that included in the weight.

    I believe the only forced induction was on the Chevy Corvair and Olds F-85 Cutlass. Both were turbo charged. As far as I know the only fuelie cars were the corvette and thunderbird. It's interesting that the Chevy 396 and 427 are 13 lbs apart, seeing how they are basically the same engine. Perhaps they have different intakes(aluminum vs cast)?

    What 427 is it? Some had optional aluminum intakes but others were cast iron to he best of my knowledge.

    in comparison to this I would like to see the weight of the all alloy BMW 3.2 liter V8 engine, used in several models ranging from the 502 to the 3200CS as late as 1966. This engine has always been mentioned as the inspiration for designing the small block V8.

    All the truck motors had cast intakes, there were 2bbl, 4bbl, and tri-power cast. I think the only aluminum intakes they had were 4bbl.

    I am trying to remember if Car Life or Car & Driver had 1966 specs for European cars. I think Car & Driver had general specs but can't remember if engine weight was included. I'll see if I can one of those magazines in my collection.

    Unfortunately, there is no explanation of "engine weight" except that some are listed without the flywheel.
