Hippie Posted August 16, 2003 Report Share Posted August 16, 2003 I'm not trying to "out" anybody as I know how popular this swap is with most of you but I like torque and the sound of a V-8, I'm going to do one and I'm looking for some info. If you want to start a debate on the evils of the 4.9 start your own thread please. I have the complete drivetrain and PCM from a 'low mile '95 Sedan DeVille and I have decided to swap it into a '90-'94 Lumina Coupe. I have questions about the wiring mods required to mate the Cad PCM to the Lumina, radiator capacity and axle mods. If anybody is willing to fess up to having one I'd like to hear from you. This is a "low buck" project so hauling everything to ASG and handing them a check is NOT part of the plan, I'm doing everything possible myself, although they do have a few goodies that could come into play, especially the wiring instructions....... I figure if I can build my own house from the footings to the ridge cap, build 6 PC's and build a 305 SBC that my old room mate "Dangerous and Delinquent Dave" couldn't blow up on his drunkest night and a 383 SBC that another friend who was trigger happy with the nitrous button never blew I can do this. Afterall it's not "quite" rocket science..............Thanks. Quote Link to comment Share on other sites More sharing options...
phantomshado Posted August 16, 2003 Report Share Posted August 16, 2003 I've been looking into this myself for quite some time now. However, upon looking, I'd say that you should put the 4.9 back in a j/y. Cadillac also had a 4.6 and a more rare, but still potent 3.5L "Shortstar". The 4.6 will fit better, and it offers comperable performance to the 4.9 and still has better fuel economy. Quote Link to comment Share on other sites More sharing options...
Hippie Posted August 16, 2003 Author Report Share Posted August 16, 2003 I'd say that you should put the 4.9 back in a j/y. I have been modifying cars for 30 years, the 4.9 fits my requirements for this particular project and my budget. End of discussion. Quote Link to comment Share on other sites More sharing options...
Brian P Posted August 17, 2003 Report Share Posted August 17, 2003 You'd be better off looking at the forums at http://www.60v6.com (gmforums) look for tdaniely he has done it to a Lumina matter of fact! Quote Link to comment Share on other sites More sharing options...

bluegp Posted August 17, 2003 Report Share Posted August 17, 2003 I'm going by memory here (and that's not too good), so some details may be wrong: Did you see the article that was in Hotrod (I think) magazine? It was maybe 5 years ago. It was a '95 - '99 Monte Carlo or Lumina with this transplant. I don't think it was a tech article, just a featured car. It may have some info on transmission/transaxle usage. I still have it somewhere; if I can dig it up, maybe I can scan it for you. Quote Link to comment Share on other sites More sharing options...

supreme_style21 Posted August 18, 2003 Report Share Posted August 18, 2003 What was the V8 that some company had put in a Lumina? Quote Link to comment Share on other sites More sharing options...
Hippie Posted August 18, 2003 Author Report Share Posted August 18, 2003 Thanks, Brian. I contacted Tyre and he was a HUGE help. He put my mind at ease on several issues I thought would be a problem. This will be easier than I thought, not a weekend "drop in" but I've been involved in worse. ASG is the company that does this swap and they change the sleeves and pistons to raise compression to 10.5 and up displacemt 0.1 liter to 5.0. Their kit includes some other mods aimed at increasing RPM and HP but I'm more of a low end torque guy. Plus I'm a cheap old b*st*rd and their stuff is NOT cheap. I have a lot more fun scrounging through the junkyard than I do writing people checks for things I'm capable of doing myself. Quote Link to comment Share on other sites More sharing options...

I'm not very organized, so I don't know if maybe a few issues were misplaced or I just overlooked it. Oh well. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted August 27, 2003 Report Share Posted August 27, 2003 get the Aurora V8 or Northstar, more tech, more power, better sound, lighter wieght, MO BETTA ok, stupid question time but i want to get this straight. the Shortstar engine - is that a Cadillac engine or Oldsmobile? and what about the Aurora 4.0 V8? is that basically the same engine with two more cylinders or? then there is the Cadillac Northstar V8.....is that related to the 3.5 "Shortstar" or 4.0 in the Oldsmobile Aurora's? or completely different? i'm confuzzled. i myself wouldn't bother with swapping in a Shortstar considering i beat one up to 50mph with my 3.1.....too much work and not worth the effort. joshua Quote Link to comment Share on other sites More sharing options...
91GranSport Posted August 27, 2003 Report Share Posted August 27, 2003 I'm surprised to hear that ASG is still around. I haven't heard from them in almost a year. Thanks, Brian.

91GranSport Posted August 27, 2003 Report Share Posted August 27, 2003 I know exactly what you're talking about, and it was Motor Trend. I seen the article and it featured pics as well. It was a red Monte Carlo Z34 but they stuffed the Cadillac 4.9 V-8 in it as well as the matching 4T60 (I think it was the 4T60) transmission into it as well. I looked through the last 7 or 8 years (yes I still have them and back another 10 years before that) of Hotrod, Popular Hot Rodding, and Car Craft. I couldn't find it.

91GranSport Posted August 27, 2003 Report Share Posted August 27, 2003 Let me clear this up for you dude. Northstar 4.6L V-8 = Exclusively Cadillac, but uses a lot of technology derived from the Chevy 3.4L Twin Cam and Chevy 5.7L LT-5 V-8. Aurora 4.0L V-8 = Exclusively Oldsmobile, but very closely related to the Cadillac Northstar engines. 3.5L Shortstar V-6 = Exclusively Oldsmobile, uses the same technology as the 4.0L Aurora V-8. So, if you think about it, all these DOHC multi-valve engines use technology derived from the non-so-reliable 3.4L Twin Cam engine and 5.7L LT-5 V-8 engine! ok, stupid question time but i want to get this straight. the Shortstar engine - is that a Cadillac engine or Oldsmobile? and what about the Aurora 4.0 V8? is that basically the same engine with two more cylinders or? then there is the Cadillac Northstar V8.....is that related to the 3.5 "Shortstar" or 4.0 in the Oldsmobile Aurora's? or completely different? i'm confuzzled. i myself wouldn't bother with swapping in a Shortstar considering i beat one up to 50mph with my 3.1.....too much work and not worth the effort.joshua Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 27, 2003 Report Share Posted August 27, 2003 You might try contacting Jeff Anton, Bungee91@hotmail.com. He had an ASG Series I Lumina, although he didn't do the swap himself, he had to pull the engine and rewire it for some reason. For those that care, Aurora 4.0L is a smaller bore Northstar 4.6L. They are essentially the same engine. 3.5 Shortstar is the same as the Aurora and Northstar but with 2 cylinders lopped off and a balance shaft added.

Sam96SL Posted September 12, 2003 Report Share Posted September 12, 2003 I (like Hippie) have been into various makes of cars for over 30 years.....part of the *joy* of the hobby is making things *fit* where they're not supposed to fit. However those of you who look for *bolt-in* solutions shouldn't look down on us oldies with differing experiences....It would be nice for all of us to progress together and not put *anyone* down because they didn't do it a *certain* way....Thanks for letting me vent.....and BTW Hippie....post your pictures here so we can all share if you have that in your plans.
