    Which of the two "sweet sixteen" (16 HP) Briggs & Stratton engines would be better in terms of overall reliability, and torque?

    Both of these engines were used on some of the largest garden tractors produced in the late 1970s/early 1980s, but the cast-iron single was obviously the one to be phased out.

    The two engine options I am discussing (in the 1978-83 period) are:
    B&S 326430 series single-cylinder cast-iron
    B&S 401410 and 401700 opposed-twin (402400 and 402700 I/C)
