Who's done the 3.4 swap? How long has it been running? What mods do you have done? Future Plans?

I've got a 3.4 in my 88 Firebird. My mods include:
Edelbrock 3790 Cam & Lifters
COMP Cams Magnum Steel Roller Tip Rocker Arms 1414-12 (1.6 Ratio)
COMP Cams High Energy Pushrods 7816-12
COMP Cams Valve Springs 980-12
PaceSetter Headers 70-1206
Magnaflow Cat

I used the 3.4 oil pan and injectors in the swap and I've got about 7,000miles on the swap. I love it, I have lots of low end torque and get pretty decent gas mileage if I don't beat on it.

My future plans are to swap to '165 ECM and DIS.

You dynoed it by any chance? And if not, what difference does the butt dyno notice?
I have one in the works...just waiting to for some more cash to have my car towed, I have similar goodies going into mine, and did you have interference with the VCs using 1.6 rockers? I've heard mixed opinions on whether or not fiero VCs are needed.

My mods are a 260 grind cam from delta+lifters, pacesetter headers, ported heads and intake, also have a magnaflow cat+dynomax catback, K&N filters, gutted airbox, MSD igntion coil, cap&rotor, taylor spark plug wires, and did have AC delco rapidfire plugs but can't use them in the 3.4
Anyways, we should have somewhat similar output levels, though mine will probably be a little higher as I have more mods in it, less you just left some mods out, you do have me on lift, but my porting will probably make up that difference, so its really a matter of which intake setup you have and if you have a catback or not :P
I plan to swap to the DIS as well, but for ECM I am going to go with a megasquirt system.
Did the oil pan clerance everything ok? I hear mixed opinions on it, but would really prefer to use the 3.4 one as its in much better shape(no rust, and paint not worn off at all, no dents either..)

Haven't had it on a real dyno but but dyno say that it pulls stronger off idle to about 4000rpm with the cam/rockers. It does have a posi and it will lay two stripes if I stomp on it. It feel like a lot more torque than a stock 3.4.

I wouldn't call it a performance catback but I do have a 2.5in exhaust from the cat.

The valve covers cleared for me, I used the 2.8 covers thought not the 3.4 ones, I actually wasn't even aware that people said they didn't fit until after I installed them. And the pan fit fine, with the stock exhaust and the headers. I really didn't want to change the pan so I dropped the motor in first, I was so happy it fit!

I really want to see some dyno #s on modded 3.4s Anxious to see what mine will make but have to wait a while and would love a ballpark figure =/

if i could ahold of the dyno i could do a non boost run, ive been wanting to just cant get ahold of them. obviously cant do a boost run really till i get a new clutch.

im willing to guess though and i bet my car might be near 200hp i dont think its more than that though and there isnt much else i couldve done to it

Project 3.4 Camaro

Well if you get one please PM me the results, also are you using multiple vee belts or serpentine setup? And how did you modify the 3.4 intake, I've often looked at that thing thinking it should be relatively easy to make it a lot better, I just never really came up with an idea I liked, except maybe lopping the bottom off a 2.8 intake, and mounting that to the top of it, and using two throttle bodys or a dual setup from a v8 or something to that effect. Trouble is I recall reading that intakes are designed to be half the vollume of the engine displacements and I imagine there is a good logical reason for that...but Idk.

Pillsbry10

iTrader: (1)

they will be posted when it happens, i emailed them just now so we shall see. serpentine setup and theres a thread on how i made the intake work

Project 3.4 Camaro

Can you link the thread, and when you say made it work, just to use it? or did you improve the flow characteristics of it? I hear the things are terribad upwards of 4.5-5k rpm.

Pillsbry10

iTrader: (1)

just made it work..added turbo to improve flow...or force flow lol

Any one else with a 3.4?

Old question yes, but just going to say I have 1.6 roller rockers on my 2.8 with stock valve covers, and they work fine.

I was going to do one,now I dont know,I got a 95 camaro 3.4 and sounds like it might not work acording to the swap bogie.I dont know what is difrent about a 95 and 94.Got it in and it even started.

Pillsbry10

iTrader: (1)

There are zero differences between 94-95.... I don't know y people keep thinking that

Project 3.4 Camaro

Apparently because of the swap sticky that says 93-95, also some people seem to think 95s were all 3.8s because there was a switch mid year, my best guess anyways.

I've got the motor on the stand and ready to start switching parts over.If I was to use the injectors from the 3.4,would I put them into the 3.1 fuel rail?Do I have to change the flywheel and harmonic balancer?ked85 in his swap said he keep the 3.4 exsaust manifolds in his swap.Dose it matter which ones ya use?

I pulled the 3.1 out of a firebird/90 modle.Put a 3.4 out of a 95 camaro in.I should have used the 3.1 rocker covers,the camaro ones worke but had to make mod to conect the tube.got the 3.4 oil pan,the 3.1 balancer,and for now I got the 3.1 injectors,because I knew the worked.Might try the 3.4 injectors after we get some miles on the swap.I've never done anything this invalved before.The one big thing that didn't seam right was how close the knoc sensor is to the starter.It even touches it.The fan hasn't come on yet as far as I have sean.I checked the manuel and I couldn't find the temp the fan is supposed to come on at.I seam to remember some one saying about 228.But not sure if that was a v8 or v6.What should the normal running temp be? Seams to run around 215.

Project 3.4 Camaro

around 200-220 for either

got a 3.4 from a 95 firebird in my 87 camaro, i used he 3.4 intake and retained my factory distributor. HUGE difference over the dickered 2.8 i had.

Killert

iTrader: (9)

Pictures? Did you cut up the intake around the distributor?

Pillsbry10

iTrader: (1)

Yea I wondered the same thing

Chevy8588

iTrader: (1)

yes. the vacuum crossover was clearanced for the dizzy, anyone who wants an inake clearanced can send them to me and i can have them done for cheap, ill take pix in a bit

sam24th

iTrader: (1)

Yes please take a picture of your intake. Im currently doing the swap and would like to maintain the 3.4 intake. Im in the process of swapping parts over and moving the sensors.

Pillsbry10

iTrader: (1)

There's a whole thread on mine just do a quick search for 3.4 intake. Lots of pics

sam24th

iTrader: (1)

Found the thread. Looks like you just notched it out. Im guessing you had no ill affects from doing so? Im gonna give mines a go also since itll end up in the trash if it doesnt work anyways.

Pillsbry10

iTrader: (1)

ran perfectly fine when the motor was stock....runs just as good boosted now

sam24th

iTrader: (1)

Alright cool ill notch mines out for a try tomorrow or some time and use it. I prefer the look.

Chevy8588

iTrader: (1)

it's not just a notch, it has to be notched out, then an aluminum strip has to be tig welded in otherwise there'd be no vacuum and your engine will probab;y race like a mother ****er, IF it even starts

Pillsbry10

iTrader: (1)

heres a bunch of pics of how mine was done...yes its a lot more than just a notch

sam24th

iTrader: (1)

Well I knew its more than I notch. I mean it didnt take any major fabbing except blocking off the piece you cut out. I think ill run my 2.8 intake for now until I get around tot he 3.4 intake. Been trying to jsut get the damn thing int he car and running. Still a few minor things left to do. Also does anyone have any good pointers on how to remove the plug on the rear passenger side head for the fan sensor? If not I might just run a manual switch for the fan and call it a day.

Pillsbry10

iTrader: (1)

you have to switch to the 3.4 throttle body as well as a heads up.

can you not just buy a new one? might be easier...i didnt have to worry about that as my car doesnt have one. its controlled by the ecm

sam24th

iTrader: (1)

Well I can buy a new sensor. But I still have to take the plug out of the hole. Thats the problem Im having. The plug wont come out.
