with alot of work you could put the L67 in it. thats the supercharged 3800 engine. i beleive its a series 2 supercharger correct me if im wrong tho.

From a practical stand point, you already have the biggest motor that will drop in. Anything else would be just to expensive and time consuming. With the right internal and external modifications, the 3400 will hold it's own.

3500, 3900, are the same block, the 3500 is just bored out w/ 200 hp and the 3900 is bored and has VVT, 240hp, 6 speed manual is avalible with it too, but thats gonn abe alot of money

how much money would you say...to convert it to a manual..everything said and done

well, what do u mean, like 6 speed in ur 3400? i dunno, i think* dont quote me, that the 3900 6 speed will prolly work, scince the 3900 is a deterant of the 3400, but it would be quite a bit, look online

Not very many 3500 and 3900's in the junk yard.
Have you considered going turbo? A pair of 3037's would make it a rocket car.

It's noble to want to mod your Grand Am. But Grand AM's are NOT muscle cars. Why not find an older 5.0 Mustang? Like a 93 LX model. Your money will be better spent.

grand ams aren/t muscle cars, youre right. thats why i want to mod it so bad. I aleady have a 64 Mustang Coupe, and i have the grand am. the pontiac is my project car. just trying some stuff out as far as glassing, electronics, stereo, kits, anything and everything that i can do.

yea, and that era of mustang is dusgusting anyway, and fixing up a mustang is so overplayed, why not fix up a grand am? that would be less expected. But if yor serious, you could do anything, but a direct bolt up, go with like, a 3.6 DOHC VVT or the 3900

3400 is the best bet. Perferably with a 5-speed.
Cavalier/Sunbird guys drop 3400 motors into their cars and they bolt up directly to their 5-speed trannies. Instant High 14 second car.
Put a Charger or Turbo running 10PSI (Which a stock 3400 can handle) and you'll be in the 13's.
The L67 is a fast motor...but all the money and time spent fitting it and making the mounts work could be better spent on a 3.4 DOHC which can produce more power N/A then the L67.
All in all...the 60 Degree V6's are the way to go.

3.4 DOHC stock isnt as powerful as an L67, 3.4 dohc has 215hp w/ auto matic from 91-93 and 220hp 91-93 w/ manual, and then 94-96 had 225hp auto or manual. 225tq either way
slowbird
08-23-2005, 10:36 PM
The DOHC motor had computer De-tuning cause they were destroying trannies when they first tested them. It has ALOT of potential.

im pretty sure your wrong, because on the w-body forum, wich they specailize on the 3.4 dohc cause there in all but the regals, and i have NEVER herd that in my life, they dont have much potental unless u got alot of money, they have almost 0 aftermarket

if you really want a project, do a 5spd swap. there's a guy on the beretta boards with a 5spd 3400 with a ET around 14.3 with nothing but open exhaust.. you could be in the 13's all motor easily with a few mods.
i think you could do it for under 2 grand - but you'll be on your own about alot of it. the swaps i've seen are using the getrag 282 from a V6 beretta/cavalier/sunfire.. it's easier to drop the motor in when you already have a 5spd car, like the J bodies, and the berettas that i've seen with the swap done were able to use interchangeable parts from older berettas ( have to weld in the tranny mount, but the center console, shifter, axle, clutch pedal etc are from basically the same car ). i've never heard of a 3x00 GA with a 5spd swap ( even though i always encourage it ); you might run into issues none of the L or J body guys have.
definately worth the trouble though.
i don't know about a 3900.. there's no way your ECM would know what to do with it - you'd have to swap the wiring harness and ECM too; might as well just buy a new car. a 3500 wouldn't be much of a leap in HP for the trouble it would be to swap it either.

Nope...I'm right ;)

I agree with Voyager though....the 5-speed would be the best bet.
Just hooking up a V6 tranny to work with OBDII is the issue.

they did detune them a littlefor the auto, ur right, but not by alot, 5-10 hp less for the auto

The main power difference between Auto and Manual was mainly from the Auto tranny robbing all the power. Some guy on 60degreev6 dyno'd a DOHC on an Auto and then the same motor on a Manual tranny and it worked out to a 28% loss of power from the Auto compared to an 18% from the Manual IIRC.
About the Huge computer detuning...don't believe me. It's irrelevant anyway. I've said too much already.

computer detuning, ha, ur so full of yourself, and mechanical detuning, thats more like it, prolly every engine made has some kind of mechanical detuning from the prototype, you might get like 5 hp from the computer

Who said anything about running a chip and getting insane power out of it?!?
and with just a chip they could have like massive amounts of power
You posted that BS on another board! I didn't say anything like that! :twak:
...and yes...it HAS been detuned...ALOT...I always heard it was computer detuning...I guess it was both Mechanical and Computer.
EITHER WAY...the DOHC has more potential than a POS L67. Which was our earlier discussion.
You said in an earlier post:
im pretty sure your wrong, because on the w-body forum, wich they specailize on the 3.4 dohc cause there in all but the regals, and i have NEVER herd that in my life, they dont have much potental unless u got alot of money
You never heard anything about the DOHC being Detuned? Of course you didn't...cause you're a dumbass. :buttkick:
So now they have told you it DOES have potential and now you know better.
You should try going on a real messageboard...where a guy is running an N/A DOHC at 257WHP and 230WTQ. He's got some Big stuff done to the motor but it's still N/A...it still needs a good fine tuning...and it still has stock Exhaust, Cam timing, Throttle Body, and Intake Manifold. POTENTIAL POTENTIAL POTENTIAL
So listen kid, (cause that's what you are) before you go running to bigger boys on another board and talking slander and Bullshit about me, try being a little more mature...learn how to be civil.
Then you will have learned 2 things today.

u mean Aaron? lol, hes so full of himself, and you said computer detuing, you said nothing about mechanical, and any motor is detuned from the original prototype, just not like, 50-100 hp lost off computer detueing, like YOU said, any motor has potential, 3400 has it, 3100 has it, any motor has potienal
slowbird

I KNOW I said computer detuning...and if you actually READ my last post you'll see how I admitted that.
YOU went on some rant on another board, saying how I said a CHIP can make the DOHC super powerful. I didn't say that. That was you being an ignorant ass. I said the DOHC has been majorily de-tuned cause it was originally too powerful...and it has been. I was wrong thinking it was only computer de-tuning...it was mechanical aswell. Again...I admitted that already. (try reading)
But None the less, my statement stands that the DOHC had the BALLS once upon a time and can have them again!
Our argument started when I said the money and time spent on an L67 swap would be better spent on a 3.4 DOHC cause they can produce more power N/A.
...and it CAN.
You disagreed and you were WRONG!
You're little post on the W-Body board showed that. They all heard about the original setup...you can bring the DOHC back to that. If it produce that much power before...it can again.
...and no...not every motor has potential. Some are just not worth the $$ and time.

What does potentail have to do with time and money, the 3400 isnt worth it, niether is the 3.4 dohc, but they have potiental. and they do have potiental i guess, but not a little chip like u said, and said you were wrong, so i dont see how ur saying i was wrong, mabye saying they dont have potental, but it would cost a ton of money due tot he fact they have no aftermarket, and where the hell did i say that they wernt detuned at all, i just was dissagreeing that i never herd of massive amouts of power loss from COMPUTER DETUNING

Can you even read English?!?! Where the hell do you get this from!?!?
Show me where I said a "little chip " can bring the DOHC all this power and glory.
The 3400 isn't worth it?!? Are you nutz? And what...is that 3.1 of yours worth it. A built up 3400 can make tons of power...and there is aftermarket parts available...you just have to know where to look.
You want to know how you were wrong?
1. After I said the DOHC can produce more power than the L67 can, you said no. WRONG!
2. Saying I said a "chip" would make the car have tons of power.
WRONG!
3. Saying the DOHC and 3400 are: "not worth it. "
WRONG!
4. Saying on many occasions that the 60 Degree Motors has "NO AFTERMARKET" WRONG!
I was wrong too, you say? Yes...I thought it was ONLY computer detuning, but it seems it is mechanical AND computer detuning that brought the DOHC down to sane levels of power...and guess what?
I ADMITTED I WAS WRONG ABOUT THAT IN MY LAST 3 POSTS!!!
Try reading...take your time. Read the words out loud if you have to.

ok theres where u say a little chip would do it, scince, u know, the chip IS the computer :roll2:
and 3400 is definatly not worth moding, and compared to a LS1 or L36/L67 there isnt much aftermarket, but my Turbo 3.1 is easier to make a 13 second car for cheaper than any 3400, even with a s/c they dont even touch 13's, they go from high 15's to mid to low 14's, not a huge jump

:lol: WRONG AGAIN! :lol:
12 Second 3400 (http://www.v6z24.com/registry/89jyturbo/)
Stock 3400 engine with 10PSI from a remote mount turbo.
12.594 @ 114.7MPH Not even on a full slick.
Another friend of mine has a 3400 in a Cavalier vert running 9PSI on a centrigual and ran a 13.8! That's with Saggy suspension, a heavy ass Convertible and street tires. Non-Intercooled.
The 3400 is a capable motor...and don't compare it to an LS1. What kind of idiot are you? Comparing a 5.7L V8 to a 3.4L V6.
Damn you're an idiot.
Where are the moderators? Are they gonna lock this useless post already...I'm tired of educating this kid.
