I beg to differ
a 292 is ..
NO .. longer than any L6 , 194,216,230,235,250,261
w/ the exception of 302's & 308's. taller than most by 1.75'', lighter than 216 & 235's
some had 2 & 3 groove pulleys
you can find a 1 groove pulley.
they have a V8 type bell housing as opposed to the 216/235 one
i have a pusher fan on my 292 radiator
