    The SBC is called a mouse motor, and sence the BBC is bigger, (DUH) it just makes sence to call it a rat motor.

    SBC blocks are way smaller that BBC blocks
    the biggest SBC is a 400
    the smallest BBC is a 396-402

    For some reason, I felt the need to research this... asked some gear head friends and they are stumped too... good question, Burt /forums/images/graemlins/thumb.gif


    Found this on a Corvette terminology page.

    Big Block Chevy The 366, 396, 402, 427, and 454 Mark IV family of engines. There have been other variations in the aftermarket world and in the Chevrolet special products world of aluminum engines for Can Am and for boat racing but those are expensive and you will rarely see one. The 366 is an old truck engine from the mid '60s and is probably equally rare today, even though many were built.

    Rat, Rat Motor Big Block Chevrolet engines 366, 396, 402, 427, and 454. These engines were called this due to the staggered patterned of the valves, which stuck up at different angles like the quills of a porcupine.

    assuming they shortened it to "rat" because it's easier to say/spell? /forums/images/graemlins/confused.gif

    Mouse, Mouse Motor The nickname for the small block Chevrolet engine, named such because the big block was called a "Rat" and so the small engine must be a "mouse".

    Just a slang term that started in the 50's I believe. A SBC was called a "Mouse" motor and the BBC was called a "Rat" relating to size.

    heres my .02 back in the mid fifties early sixties when The Chrysler Hemi(Nicknamed an elephant motor ) was dominating the drag strips the small block chevy had just been introduced and was soon found to be almost as fast as the hemi and it was said that the "elephant" was scared of the smaller "Mouse" motor the "rat" designation was just a an add on to the "mouse" with the later intro of the big block in 66' befrore that the "big blocks " were the 348 and 409 "W" motors any ways that's the way I understand the small block has been around about 10 plus years longer than the bigblock so it was mouse then RAT

    One more (from a racing friend of a friend /forums/images/graemlins/grin.gif ) that says the mouse came before the rat:

    The SBC motor was introduced for sale in the Fall of 1954 and was much smaller in size than the existing motors used by other manufacturers. It also was one of the first to make one horsepower per cubic inch. Competitors started calling it a "mouse" motor because it was so small in size.

    Later in the Fall of 1964, when the BBC was introduced, folks thought of it as a bigger, more powerful cousin to the SBC "mouse" motor, so they called it a "rat" motor.

    I like yellowk20's better tho /forums/images/graemlins/ears.gif

    366 tall decks rock the house! My neighbor has one in his 1938 Farmall F20 and it will pull a 6 bottom plow about 8" deep at 1000rpm.
