Default Difference between I6 and V8 Th400?

I found a Turbo 400 local that I'd like to use, but if I'm not mistaken, don't all 90deg chevy engines use the same bellhousing?

I'd like to run this behind a 5.3 (with crank spacer of course)

It was originally behind a 70s 250I6 in a full size truck

A 250 inline six Chevy can be replaced by a sbc or bbc popular swap back in the day without touching the trans

Now a t400 behind a 250 I am not so sure about are you sure it's a t400 not a t350 ?

wierd, i have never seen a 400 behind a six, doesnt mean they didnt do it, i fig maybe a 292 6 cyl maybe, not a 250, but i guess in keeping with the heavy duty theme maybe thats what they did
is it a short tail housing 400-either way it should work fine-there is some diff in the bell housing area, but i think more from the process (mold) it was poured into when it was made

Of course this is just what I was told. I'd take it with a grain of salt lol. Also, I believe the casing is a 68 from what I gather from a serial number. So maybe it didn't come factory, but it did in fact come from that truck (that happened to receive it as a transplant years ago)
