I went to the yard again.
To grab a few more items.
V-8 Trans Am Muffler
EGR
Tailight
$34
But while I was there I decided to try an idea.
I found that V-6 Fiero from which I took the valve covers.
The Fiero upper intake was loose, plopped it onto a F Body V-6.
The Fiero TB enters at the alternator location.

The Fiero intake set up is the same as the F Body. Except TOP PART. The pretty cast designed part.
I believe even the lower intake is the same, just different fittings for the thermostat housing & that's a bolt on.
Went one step further. Took the Fiero TB & the F Body TB.
The opening size is identical.
Now fitment onto intake.
The Fiero TB turned upside down has the best chance of fitting.
BUT WHY.
That way the linkage "lines up". Closer but still not correct.
Here's the best part.
Know the opening direction of the F Body TB throttle plate?
Upside down, the Fiero TB opens in opposite direction!
Meaning, anything ya can do to a Fiero TB (enlarge, etc) you can do to your current F Body TB.

To make a Fiero intake work on an F body application, one must cut the front neck of the F Body intake, weld that onto the Fiero intake.

Only great scores from Fieros are the Seats with speakers in headrests.
Valve covers.
EGR as an option car to find a good used one, cheap.

The Fiero 2.8 can be swapped for a FWD 3.4 engine, also. Not "really", but a F Body 3.4 can also be made to work.

hmmmmmmm.......theres a 2.8Lv6 fiero sitting in r driveway.....

KED85

Imagine the 3.4 from a Buick Rendevous
The DOHC 3.4 I believe is too wide
I have seen numerous 3.8 supercharged swaps
BUT find the 3.4 FWD BLOCK, use the F-BODY 3.4 (THEY ARE BETTER!) heads, use your current Fiero intake/ignition system.
You are done!
Or drill & tap starter holes on opposite side of the 3.4 block from the Cam/Fire cars.
Rest of your current stuff lines right up!

This/these thoughts is how I deduced several advantages of using the later model 60* designed 3.4 block for my 1985 Firebird & Blazer swap.

FINAL CLUES.
All/Many parts will fall into place when both 2.8 Fiero & 3.4 (?) vehicle long blocks sit side by side.
Oh yes it is a TRUE win-win!
Get them like me, lowest milage 3.4 survivors.
No rebuild costs yet.

Hey, I want to put an alumumn 6 cyl. engine in a Fireo I'm gona call it - .... the Corvair .

krazycracka55

and im going to drop a ls1 in mine!

Laugh out of ignorance if you must.
Fact is there are 2 LS1 fiero's, a few LT1's, a bunch of SBC 350, 3800 SC fieros running in the 12's (1/4 mile not 1/8) and yes they do have time slips. In addition to those there are 4.9 caddy fieros, 4.3 fieros, 3.4 fieros, Quad 4 fieros and even some japanese motor swaps. There is a guy running a NX Express kit on a fiero 2.8 doing 12's in the quarter mile and he also has a timeslip. A stock 2.8 fiero will blow away a 3.1 Firebird or Camaro. Things to think on.

For the record I like camaros and firebirds more than fieros, except for the 1990 fiero protoype that GM execs claimed rivaled vettes. Everything I said can be proven at www.fiero.nl

Have a nice day.

dennis6

Oh forgot to mention Big blocks have also been mounted in Fieros. I know of a few 454's and atleast one caddy 502. There are even people who mounted a big block ferrari style instead of the transverse set up. For the regular V8 swaps go to www.v8archie.com (sbc and lt1)

There are some northstar swaps also.

Makes me wonder why people cry about a 2.8 to 5.7 fbody swap.

KED85

I wouldn't cry about a 6 to 8 F body swap.
I'd junk the 6 car & just purchase a V-8 car to upgrade.
Fieros you have to start at ground zero.
As there are no options for engines.
No laughing, I love Fieros!

I met the guy you're talking about (Travis. with the orange GT) with the 12 second Fiero at a show last weekend...they can be pretty impressive cars. They're 1000lbs lighter than an F-body, have few traction issues, and the drivetrains hold up very well. The funny thing is, his motor is stock except for a $350 piggyback computer and the NOS...no cam, no ported heads, nothing! It impressed the crap out of me. BTW a stock 2.8 5 speed Fiero will beat most stock 3rd gens, including a 305 TPI auto.

And with F-bodies you don't? Even if you start with a V8, most of them are pigs stock, even TPI 350s.

Actually, its far easier than an F-body 6 to 8 swap, because you don't have to change the trans or rearend, and there are fewer pieces to buy. According to V8Archie, the axles don't break even under high HP V8s, and he has never broken a transmission either...the Getrag designed 5 speed is far stronger than the weak T-5s put in F-bodies. The kit isn't cheap, but the swap doesn't look to be that bad at all.

For those who don't want to go to the trouble, its been shown that NOS and a few bolt ons can get you 12s with the 2.8.

DAN_92RS

yes i have seen these v8 swaps on the fiero done before its not easy though. my freind mike who is like the muscle car genius in my town has done this. he pretty cool but hes a ford guy but he likes chevys a little bit.

dennis6

Swap is much harder. You have to lift the fiero and drop the cradle out of the bottom. The auto trannys have been blown up many times before, so most find a different transmission and have to make a fwd tranny work with a rwd car. Then there is the custom wiring...

Fbody swap would be much easier.

LT1guy

iTrader: (1)

Being a 4th gen guy, the whole cradle thing doesn't scare me too much...it could be done in a weekend. The autos arent as strong as the 5 speeds, but the 12 second one referenced is an auto, and as far as I know he has had no problems. Wiring is no worse than it would be putting a TPI in a V6 F-body, and if you're going carbed it would be ridiculously easy.

Yes Travis is his name, he goes by 1FST2M6 on www.fiero.nl

1989/1990 Fiero Pics for those who think the Fiero was cancelled becasue it was a piece of crap.... Can you say vette killer? Yes they ran, and yes the factory was already tooled up when the order from GM came to kill it. Note it was GM not Pontiac that axed the car.

Fiero with Nitrous running 12's does not put off the same amount of torque as a 350 SBC.

LT1guy

And who cares if it does? If a guy in a lighter car with better traction but less torque beats you, he still won !

KED85

Fieros you have to start at ground zero. As there are no options for engines. No laughing, I love Fieros!

And with F-bodies you don't? Even if you start with a V8, most of them are pigs stock, even TPI 350s.
Very true.

Most V-6 people here wouldn't pull off an easy V-6->V-8 swap on a third gen.
And why would anyone want to?
V-8 Third Gens are a dime a dozen out here in Los Angeles and also most other locations. Start with the right vehicle foundation to modify, make the effort easier.

The Fiero is a great ride to modify, too.

If I do a 6 Cylinder Swap to V-8, it's in my Wife's/Son's 1968 Camaro.
Something worth the effort to do it right.

I do my 2.8->3.4 Swap Boogie for CA smog legality and ease of a swap.
I have no complaints on my V-6 swap results.
And I save $300.00+ on not having to vist a CA smog referee in this state for the privlidge of getting my bi-annual smog check to keep driving this V-6 swapped vehicle on California roads.

My Firebird & my Blazer cost me $40 a year to register & smog tests are same price. That's close to free for me.
I gave up on illegal smog results ages ago. It was costing me to much for the hunt (had to find a new ($$$) guy everytime, previous resource was closed down).
That's why I own also three smog free cars & two motorcycles. Those I modify with glee!!!!!


Actually, its far easier than an F-body 6 to 8 swap, because you don't have to change the trans or rearend.

On one of those two details you are correct.

If you have a carb'd 3rd gen F-body V-6, SWAP TO A V-8.
EVEN A CHILD CAN DO IT CORRECT & SMOG LEGAL & CHEAP!

The cool thing about Fieros can also be said about our V6 F-bodies... They are cheap to obtain, and almost anything imagined can be done to or with them. Even with the 4 cylinder the Fieros had a surprising amount of power. I wish my car weighed what a Fiero does. I would gain about a second in the 1/4 instantly.

LT1guy

A V6 to V8 swap in an injected F-body is worth it only if you already own the V6 car and its in really good shape, or it has sentimental value...both apply to Redraif's car. Otherwise, I would say get a V8 car, too.

As far as only being right about one (changing trans and rearend), the trans you have to change due to wrong bolt pattern, the rearend you technically don't...it is the same rearend, only usually non posi...but should if you want to make the most of your swap. I was talking more about high hp swaps, where a stronger rear (12 bolt or 9") is necessary.

dennis6

Less torque means longer tranny life. If you are putting a 350 in auto fiero, you should have the tranny built or swap it. The benefit of swapping it is gaining over drive. I know of two autos that will work, 4.9 Caddy tranny and 3800 SC caddy tranny. Think of the TH125C as a TH350 without the strength.

LT1guy

Sorry Dennis, I misunderstood your post...that makes sense. I was referring more to the 5 speeds, but yes you probably should beef up or replace the auto in these cars with a high torque engine.

dennis6

No problemo

I found V8 Archie a while ago, and I'm impressed as he// with them, even found one for sale on Ebay motors once & thought long n' hard about it. But people have put V8s in Volkswagens too.
Nobody but us old guys remembers the Convair & what a dog it was when it first came out; I think that G.M. was trying to build a rear wheel drive Nash Rambler.
Imagine if they had tried to build an American Porsche instead. They seem to have the uncanny ability to take a good idea and screw it up or drop the ball.
I have high hopes for the new GTOs, but I hope it doesn't wind up looking like a Chrysler reject.
I saw a picture of a concept car once - a rear wheel drive Firebird / Fireo - evidently at one time there was talk of joining the two cars into one - Now THAT is scarry.
