Why would you want to get rid of your N*? the N* engine came from a 2 peaice racing block. For less then what it would cost to drop in an SBC or LS, you can be tapping into much much more power with the N* engine.

I would recomend doing a search on PCM tuning and cam swap. There is a video on the net somewhere of a N* with swapped cams holding 14K RPM for several hours without any faillures.

Keep in mind that the N* was delibratly tammed down for the Caddilac platform doue to Cadillac's targetted customer base. (Ritered elderly people looking for luxury).

I'll see what i can digg up and post it here.

ever find this video? your sayin a stock N* holding 14k rpms?

someon said the ls3 is a near bolt in. what kind of welding needs to be done. are we just talking brackets to mount the engine?

LS4, lots of go fast parts, can make stupid amounts of power easily.
NorthStar, no go fast parts, hard pressed no matter what you do normally aspirated to make over 325 hp.

LS4 hp/$ is low
NorthStar hp/$ is high

The thread has been dead for 8.5 years. I doubt that you'll receive an answer to a general question that addresses on one, no thing. Please read the beginning (back to Post #1) of the thread for answers.

I realize that most people don't want Cadillacs for hot rods and all that, but at the same time, I see no point in having such a sweet ride, all that technology, and all that power into a car that only old people generally can afford, and then other people just keeping them mainly stock because very few people make performance parts for them. I have a '94 Eldorado 4.6 that I am absolutely in love with, and even more so do I love hearing people talk shit about them in comparison to their little 4 cyl rice burners as it clearly shows intimidation. :D I'm not an *** with it.....ok maybe a little bit, but not too much. My dilemma is this: why couldn't a Cadillac, which generally speaking you can get a little older one with the same specs and style as some new ones, relatively inexpensively, be modified to accept a larger crate engine, such as a 350 LS1/LS2, which would rocket the horsepower, without sacrificing the luxury of driving a good old Caddy? I was really excited to get to work on suping it up, with air intakes, exhaust, perhaps a universal turbo, and all this stuff, but I usually find that these motors are pretty much maxed out from the factory. Therefore, trade the motor, keep the body, and mod an engine they make mods for. I would like to drop an LS2, 400 hp, 364 6.0 Corvette engine in mine, which I could do within my price range. The hidden fees like the alternators and ecm and all that isn't really unnegotiatable either. But will it work? Can I change this car over to accept that type of motor, with ETC and all that? Will it fit? Welding and chassis work is not a problem, but this car will see some drag time, and I don't want to stick with the 6 second times forever. It's got potential to be mean and I would like to know how to harness this. If this won't work, does anyone know of another engine I can drop in it? Any ideas, answers, and opinions will be much appreciated. Thanks a lot, and maybe I won't feel like the only guy in the world that's ever considered this.

P.s. If you're one of those people who think this is blasphemy for doing this to a Cadillac or think I'm just a moron for not buying a little Mustang or something, (not trying to be rude), but please don't even bother replying to this thread, wasting my time, and making both our blood pressures rise. It's not healthy and I don't need another person to try and change my mind as it has failed to do so yet. :) Thanks again.

Rick,
Your only limit to what you can have as modifications is your imagination & your wallet.

Uh...mainly because they're FWD cars that were built to accept the range of Northstar FWD engines, and some of the older 4.5L/4.9L's. A typical workhorse 350 or otherwise small block V8 is mostly setup for RWD applications, such as trucks and certain older cars.

So, it essentially just comes down to the FWD vs. RWD issue. Currently, there ARE some FWD GM vehicles with the LS-series 5.3L (Impala & Monte Carlo SS and Grand Prix GXP), and given some basic similarities between front end components in those cars and the typical 90's Cadillac, that could be a possible swap.

But for downright drag racing and such, like you bring up, that would be mainly for RWD and any one of a number of V8's...and can be done, but it would require fabbing up a completely new understructure, suspension bits, etc.

Hope that answers something...a FWD Northstar V8 Cadillac can be made to do some pretty incredible things from a racing aspect, but are still quite complex and not really intended for that sort of thing. And no typical pushrod GM V8 will really go in that easily.

If you want to pick up say, an Eldo, and then maybe a Camaro or something and figure out a way to meld the two into one...then you might have something...but the time and money just wouldn't be worth it.
Don't forget the 91ZR1 Aluminum 4 valve V8 that has the type of performance without the weight.

Rick,
......
Stevo-,

I had to go back 13 years to find out who in the hell you were addressing! And it doesn't appear he's ever posted again here since this thread.

So newb, the first rule of posting is read all the farkin' posts before posting. If really pressed for time you could have simply checked the post immediately above yours. LOL

Oh, Welcome! If you plan on contributing then set up your Profile with at least what you're driving for other's benefit and reference.

Welcome to CF !!! Please update your profile to show Cadillacs owned/driven. Thanks.

The member you quoted has not logged in for over 13 years.

Best of luck swapping anything but a Northstar into a Northstar FWD Cadillac Seville, Deville, or Eldorado.

(There WAS a RWD 572 Deville swap done - $85,000, nothing worked but the engine and transmission. Last for sale in CF Classifieds for $70,000. Several burnout videos available)
