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

Will the 4t80 trans from a north star bolt to a 350 Chevy small block me and my buddy are building a Cadillac limo it's a 75th anny and we need to find a trans. The trans from his original car I believe was a 4t65 and we had to scrap it to get the 350 but now we need a trans for a fwd. any help would be awesome

not without a 60* bellhousing to sbc bell adaptor

id check with the fiero.nl fella's

Well do you know of any fwd trans that would bolt up to that. And I'll check that out

what year and make caddy?

why not use a caddy engine?

Cause we are mating it to a Chevy 350 it's a 1986 Cadillac fleet wood 75th edition. It's super rare

the only cars i can think of that were fwd with v8 were the olds toranado, and the caddy eldorado. cant think of any chevy fwd cars with a v8.

Uh, will the GXP trans bolt up?

isn't that just a hd tranny 4t65e

This is it's paint scheme maybe changing

Before and after powder coating

Final product

Headers

Before and after powdercoat on the intake

Last what we are working with

wait, the caddys rwd? the headers look like they are for a rwd car.


if so toss any th 350 or th 400 in it.


edit: just saw the engine bay pic. carry on lol

I was thinking a 4t80 from another caddy but we have read that we need a like adapter. I wasn't sure if anything else would bolt up

No it's front wheel drive. The headers came with the 350 I was just showing we powdercoated them

**** me if I'm wrong but isnt the 350 a 90* bellhousing? So the 4t80 should work.

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

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