the 325hp engine Saginaw three speeds were re-geared to: 2.54, 1.50, 1.00 and 2.63 rev

the same warner t16D was available in el caminos with 230, 250 and 307 also, but with floor shift when console was ordered,

and the T16D was regeared in el caminso with the 327 and 396 to: 2.41, 1.59, 1.00, and 2.41 rev

saginaw have seven-bolt side cover

the sm318 was four-bolt side cover

the 318 is not listed on the above listed page url
the above listed URL listings on four speeds dont match the elcamino four speeds, there were four el camino four speeds and the listings dont match any of them exactly right,
a couple are close to GM specs
