This goes out to all you Cadillac guys. 4t80 trans

[theaceofspades]

this guy used a adapter plate and had to trim stuff. http://www.fiero.nl/forum/Archives/Archive-000001/HTML/20070315-2-077183.html

So would we have to have an adaptor plate or not because it's the magic question.

Yeah a 350 has a 90* ballhousing so the 4t80 should bolt up. It's a tough trans but its a power robbing beast.

We are concerned to much about poweer just making it look cool and be loud. It's a limo so basically it's not gonna be a race car

im sure that guy would have bolted it right together if it fit. the 350 is old school, the new blocks changed the bell housings.


do you have the tranny and engine already? see if it mates up is you do.

 

[theaceofspades]

We just have the motor we are waiting to buy a trans

 

[Scottydoggs]

stop by a few tranny shops, see if they have a spare case you can borrow for test fitting. or maybe offer to leave a deposit on it or something.

I've got a spare trans out of our 05 GP that needs rebuilt. I'd sell it to you if it would fit.

 

[theaceofspades]

That's a good idea! I'll call around

 

[theaceofspades]

Any idea if this would work
