Alum Bell Hsg for 1960 348 4spd???

[rod61727]

Does anyone know the correct aluminum Bell housing for a 1960 Impala with 348-4spd? show cars book indicates it would be a 553, but I have a Hollander which implies that something else came from factory by saying the 553 will interchange...but it does not give a casting number for the 1960 application...a friend asked me to look in my references, and I don't want to tell him wrong...Thanks

The difference between the 553 and this bellhousing is the size ofthe clutch arm opening.

that's the bell housing that is on my 60 335hp engine but i'am thinking the lower hp 348s got the cast iron housing?

Gearhead,
I think you are right....I don't know about '60's but the '61 250 and 280 motors used the cast iron bellhousing while the 305 and up used the aluminum housings. I supect the '60 and '61 were the same.

i would think the 60s were the same way. i have seen alot of 250hp 348s with a cast iron bell. i have a 280hp 61 348 it has a cast iron bell. 62 did the same thing. alum bell housings on the hipo engines only.
