A quick question

[TorquePower]

Would it be beneficial in the long run if I replaced my 94 Grand Am GT's 3100 V6 with a 97 Monte Carlo's Z34 3400 V6 ? The Monte Carlo has 215 horsepower@5200 RPM, and 220 Ft-lbs Torque@4400.

I know of someone who's done it, not personally, but I was just wondering if I did this engine swap, would I be able to slam more horsepower and torque into the vehicle in the long run?

[Matt95GT]

That's not the 3400, the Z34 will have the 3.4L "Twin Dual Cam V6". I doubt you'll get that to fit in a 94 GA... if it does it will be a rather large and expensive project.

The 3400 OHV (LA1) would be an easier swap.

I want a horsepower and torque gain in the process, what kind of cars do the 3400 OHV (LA1) come in?

I'm actually thinking of just performancing out my 3100.

or if not swap it to a 3400, do you think it would be beneficial to swap out a higher rated horsepower/torque 3100? Like the 93 3100 in the Buick Skylark? I mean not much horsepower increase, but it is 5 horsepower after all which may benefit in the end. ( Just an example )

[Big Joe]

The 3400 OHV (LA1) come in the newer grand am's (99+) I would agree with matt if your going to swap go with the 3400 out of a grand am, by far the easiest swap there is.

[TorquePower]

Do you know the horsepower and torque ratings of the 3400 OHV (LA1)?

I don't mind difficulty, I just want to make my Grand Am the dragster it needs to be when I'm done with it, completely. =P

[ihatemygrandamg]

I have a 99 grandam 3400, and I beat my friend who has a 96 monte carlo. Its not all about power ratings

Tons of GM vehicles, 99+ Grand Ams, Alero, Minivans, etc.

There was no 3100 before 94, the 93 Skylark has the 3.3L V6, which is incompatible as an easy swap since it's a 90 degree V6.

Not to shoot down your plans, but I wouldn't count on this type of swap making your GA a "dragster" by any means.

[TorquePower]

Let me rephrase what I meant, I don't mean Dragster as in, 500+ Horsepower etc.

I meant dragster as in, Strong enough to beat these dumb little import tuner cars that are souped up.

and I know it's not all about power, it's about skill too and tranny...and weight. =).

I have beaten stock 96-98 Eclipse's with my Grand Am.

I've only lost one race with my Grand Am so far,

and that was against a 91 Buick Regal Gran Sport, with a 3.8 bored out to a 4.3(I believe). Even then my Grand Am took off faster than his buick, and I stayed ahead of him for about half a second or so and then he just overtook me with his power.

I just want to slaughter import tuners.

[TorquePower]

Just another note, I don't plan on engine swapping any time soon if I do. I might just keep the stock engine and do everything I can to it with performance mods. However, I am just collecting information right now.

You can prolly do that with cat-back exhaust and an intake. I've seen a couple 3100 powered 94-95 GT's hit low 15's in the quarter mile with just intake/exhaust... that's enough to beat most of the import pseudo-tuner sport-compacts.

[TorquePower]

Sweet, it would save me money too...Now, I attened the Greene County Career Center until recently, which I took the automotive technology class. I learned up to disassembling an engine block and reassembling, and right before I left, we were researching alternative fuels to convert an engine to run off alternative fuels.

So I just know "basics" on engines. I stated that for this next question.

Would it benefit me if I put in a "racing" cam and replaced the rocker arms, valves, push rods, and had my engine bored a little to support the bigger cam? ( Any size, but I love all cars with Full sized cams )

[xonelith]

There's a 3100 out there pulling 184 whp with cam and heads. Look around for that guy. Might be an alternative to the 3400 swap.

[TorquePower]

Thanks, I'll look for him.

[TorquePower]

I'd like to add, the reason I ask so many questions, is I believe in collecting information beforehand, and I never liked GM, this is the only GM car I've liked so far. ( Used to own a Thunderbird )

[Korbendallas68]

Pfft. You can do a 3400 swap for under $500.

Have you read the guide yet? :D

[TorquePower]

From the Mitchell on Demand program we used at the school, the 3400's I saw, in the 99+'s had a gain in horsepower, but drop in torque. I like torque, no I love torque, and I will never accept my car having more horsepower than torque.

Sure putting the 3400 in may be fun, But horsepower and torque is ultimate the best.

[Azrael]

I'll put it this way: 94-98 3100 (what you have) = 155 BHP/185lbs-ft of torque
00+ 3100 = 175BHP/195lbs-ft of torque
96+ 3400 = 175-185BHP/205lbs-ft of torque

The 3400 varies between 175-185 HP due to differences in the intake and exhaust setups between the vehicles they were used in.

As for your list above: there are no aftermarket rockerarms that are a direct fit and the cylinders can only be bored out safely to 3.2L. Search around at www.60degreev6.com for lots of info on these engines.

[VanishingImage]

someone here has a 3400 in their 96-98 GA,dunno if they have done any track runs but I assume its a little better then the 3100's that were put in those years

[TorquePower]

That's the thing, I've beaten two 2000 Grand Am's with the 3400 in my 94 Grand Am with the 3100...

[Korbendallas68]

Hmm.... It has less torque?...

My 3400 seems to be pretty nice with torque, hella better than the 3100 that was in there...

[TorquePower]

Do you think I could stick a 3400 from the silhoutte, etc? I don't know if they're the same or if there's a mounting problem or anything, but if so, I found a sheet that says their 3400's have 185 Horsepower and 210 ft-lbs of torque.

The guy with the regal said it's possible but he's not sure, he knows more about the bigger engines.

[TorquePower]

Do you guys have any suggestions where I could buy a 3400 and pay someone to put it in? I lack an engine boom and the other necessary tools. I've looked abit around here and haven't had a clue where to buy one except a junk yard...but I'd like to buy the newest 3400 I can, ( I'm hoping the 2004 Oldsmobile Silhouette 3400? ).

[NaturalKonc3pt]

I have a 3100 and i'm very pleased with mine. granted i've done some pretty extensive work but i'm runnin 0-60 in about 6.1-6.3, that was based of a car that does 0-60 in 6.9. you can make a 3100 pretty fast you just gotta take the time, i boosted mine but there are otherways of getting a good deal of power keeping it N/A, Intake, Cams, heads, Lifters, springs, PCM tuning, porting/polishing, exhaust,

[TorquePower]

Yeah, but you gotta ask yourself,
" where is the limit to the performancing of the 3100? "
I mean I'm sure it's not a big gap but there has to be a gap where the 3400 can out performance the 3100

[99blackSE]

Do the 3.4 swap, its better in quite a few ways...
