Default Will a 4160E bolt up to a small block 400?

I am doing an engine swap in my 89 Camaro. Its got a 2.8 v6 with 4 speed automatic currently. I will be going to a carb engine and want to make sure the 4160e will bolt up to the new 400 small block.

a 2.8 4l60e won't.
and there's no adapter made to adapt it to a small block.

Since the 4L60E was not introduced until 1993, your '89 does not have that trans; it has a 700R4.
I don't know if that will change Jay's answer; the bell housing bolt pattern might be different for the V6 engines versus the V8 engines.
In any case, you can assume that a nearly 20 year old trans, especially a weak 700R4, will not hold up to a performance V8.

The bell housings for the V6 and V8 transmissions are different.

In 1989 they were pretty much the same internally. No, they didn't have fewer clutches.
The 60 degree v6 bellhousing is different than the 90 degree v6 and all v8's.

I once swapped the internals out of a recently rebuilt 2.8 700r4 into a v8 case to use in a s10 350 swap.
The age isn't a bad thing, it may have been rebuilt and upgraded.

Theres nothing weak about a 700r4, they have basically the same internals as a 4L60E. Just tuning the shift points is a pain in the ***.
