: Thinking of getting a 70's Caddy

03-24-05, 03:29 PM
Hey all.

I currently drive a 1990 Sedan Deville, and I love that model/year. I think it's the best of the 90's Devilles... but... I am thinking of getting a 1970's Deville, and was wondering what you guys would reccomend.

I have been looking at some online, and the 70-74 Sedan Devilles have caught my eye.

I am looking for something that has an engine that is fully rebuildable, (unlike the 4.5 aluminum block motor in my 1990). I'd like to have the option to rebuild it if I ever wanted to.

So... do you guys have any suggestions as to the best year, as far as least known problems with the motor, tranny, electrical, mechanical, suspension, etc...

Also, are 70's caddies built on a seperate frame? or are they unibody. I'd like to have the option to do a frame-off restoration, if I ever wanted to.

Hello there, i love the '70s caddies too, if i was going to get a deville from that era i would get a 1976 Coupe deVille because IMO they are the best looking and they have decent power. the 500cid V8 has 190hp and 360 lb/ft or if you're lucky enough to get a F.I. version its 215hp and 400 lb/ft. those engines can make over 500hp if you have the $$, parts are readily available. As far as i know the engine and tranny are very reliable and are damn near unkillable as they are both H.D. the only thing i've heard of is the dash cracks easily in the cold due to it's cheap plastics. and yes they are Body on Frame. If i have excess cash lying around i would like to get a 1978 Eldorado Biarritz and get it to run high 12's to low 13's.. BTW. I Have a 1992 Sedan Deville...great cars.. i love em.

Any of them will be a great purchase. I like the 75/76 model years because of their square headlights. The 71-73 look cool too with the turn signal between the round headlights, kind of a mean look to them. All 70-76 Eldorados were front wheel drive with 500ci, 68-74 Eldos + Devilles + Calais + Fleetwood Broughams were rear wheel drive 472s. All 75-76 (except the first year oddball Seville) had the 500s. Rear wheel drive models used the rock solid TH400 3 speed auto, Eldos used essentially the same transmission just mounted all funky to drive the front wheels and called the TH425.

The only thing you need to specifically look for is rust in the lower areas prone to water exposure and under the vinyl top if there is one.

Thx for the info guys.

Do you know the availability of parts these days for Devilles from this era? If you could point me to some websites regarding these cars, I'd appreciate it.

I want to do research before I get one.

Here are two great web sites I found just today - I am a new member looking for a similar car as you...



Here's wishing us both luck in finding a good Caddy!
