Question Can a 904 tran from s6 go into v8

My first try at a Mopar transmission and I have a problem. I bought a 1975 904 tranny of the internet and was going to put it in a 1973 dart.
Problem is the tranny is off a slant 6 and I have a 318. Can i swap the bell housings and be ok?
I wondered if the gearing would be different also.
I looked around but I get only ads trying to sell me another tranny.
The wife says I am way over budget or i would just look for another tranny.

What are your thoughts?

You're probably going to have to find another tranny. The 904-G tranny you bought has a different bolt pattern than the 904-A you need. The bellhousings are integral and therefore can't be changed. The only possible saving grace is if the tranny you bought is from a truck. SOME, but not all, truck transmissions had both bolt patterns, I wouldn't count on it. You could change it over to the correct pattern with a JW Ultrabell, but that would be more expensive than finding another tranny.

That is what i was afraid of. I thout about trying the rebuild on my own. But I think that it might be more challenging than i have the skills/time to successfuly pull off. My budget and tool crib or not very well equipt.

Thanks so much for the reply and have a great day!

I have never heard of something to change a 6 cyl torque flight to fit a small block. The 6 cyl has the starter mounted toward the top. You can change the starter standing up. The small block has the starter on the bottom, like Chevy, Ford, and most other cars. No need to rebuild that one for a small block!
