Hello all ! !
New guy on the block.
Great site.
I am getting a 1970 Couple DeVille with 70,000 miles.
The oil pan has a window from something leaving the inside of the engine at a high rate of speed.
That said, I am looking for info on which engines would bolt in to run as I rebuild the stock engine.
I know the 500 will work, but what else will bolt in with minimal headaches and fabrication?
Bolting in a small or big block chevy first came to mind, but I think I would like to keep the 472.
Thanks for any and all info.
The 368, 425, 472 and 500's are all direct bolt-ins.....everything else will require mods. Buick, Olds, Pontiac and Cadillac all used the same transmission bolt pattern. Anything else will require a different transmission or an adapter (chevy trannys didn't have the same tailshaft either so if you changed the trans, you'd also have to have a driveshaft made or find one the right length.....not real likely). Your best bet would be to find another big block Caddy to drop in.
The heads on a '70 engine ("950" castings) are highly sought pieces.....don't let them get away.
Can I get a year and body type range to look for?
I had a '68 ragtop with a later 500 in it, but never got to the point of being a Caddy expert.
Loved that monster.
Thanks for the tip on the heads.
Why so special, "closed" chambers, good flow numbers?
Thanks,
Mike
If you're anywhere near me, in N. California, I've got a good strong running 472 in a 72 Eldo I'll let go for cheap...too many projects going on right now!

Closed chambers, "no-smog" and '70 was the only year the "950's" were offered.
472's were used in all cars in '68 & '69.....in Devilles up to (and including) '74....500's in all Eldorados from '70-76 and in '75 and '76 Devilles. The 425 was used in all Cads (except Sevilles) from '77-'79 and the 368 was used in '80.
Theres more than just swapping the engine too. Your rear axle ratio is 2.93:1 and the car is 4650 lbs..... Most engines are going to have a difficult time with getting the car rolling.
Spyder,
I am in Tucson (AZ, not Ohio) at the moment.
The offer is great, but how far is that?
Probably be cheaper to go buy a new Caddy than buy the fuel there and back?
Starting to feel like a European these days, but don't get me started...
Thanks,
Mike
