350hp N/A Fiero, pics!

I dunno... I dont know that much about the options and what not... It sure did sound like a raspy v6.
Looked eactly like this:

So it probably was not the duke.iron.

Fiero's look wierd with cowl hoods, knowing the mid-engine layout.

meh, if i had a nice fastback fiero i would either swap in a turbo tec or a turbo lsx

[CobraCDR]

Ummmm why not an LS1? All that trouble for an old carb motor. LS7 would be a nice swap. It has been done.

[El_Diablo]

because the ls7 is what, $12-13k? more than the cost of the whole swap most likely... though that would be my dream powerplant for a fiero... with a lil boost and a nice 5 or 6spd manual

[ForcedFirebird]

He had the motor sitting in his shop. The 2.8 had over 200k miles. Since he is a machinist/engineer, he just put the two together without a lot of money. I would slo immagine that a carb is simpler for someone who perhaps didn't keep up with ECM's and controlling them. At 65, he also probably didn't wnt to end up contorted in the car trying to run wires.

Amazing how well that 327 fits in there.

This guy did an LS1 swap- I remember reading something about it in hotrod magazine too. And he nitrous'd it.

[El_Diablo]

i remember seeing that car on the front page of PFF

[ForcedFirebird]

My buddy finally took me for a ride in it. I was astonished to say the least.

The car has the stock 5 speed with 99k miles on it. He can be cruising at 30mph in 4th gear, punch it and the tires will light up.

He is finishing up the new fiberglass front valance and Corvette tail lights, also installed the non-pop-up halogen headlights recently (and I heeeelped ,lol) Motor is comming out soon for a roller cam conversion and AFR heads. I'll get some more pics soon

I doubt its making a true 350 hp. Its probably only doing upper 200's at the crank. And probably around 230 or so at the wheels.

30 mph in 4th gear is like 1500 rpm!! He is not smoking the tires in 4th gear from a 30 mph roll. SORRY!!

Also tell him his tranny won't last long with 350 hp. Or it will last a very long time with less then 350 hp, which is most likely the case. So I would tell him not to worry about his tranny. He isn't making the power to blow it up.

Oh yea tell your machinist freind to start making kits for the fiero. He made the adapter plate and all. There is a lot of money to be made. You should talk him into making them for other people.

EH, maybe not making the true 350hp GM claimed from the motor of that year (the motor is not stock BTW, almost 10.5:SCR), but yes, the tires will spin in 4th gear. In fact, he can take off in 4th gear . This thing pulled hard for a 327, tried to watch the tach, but since it was made for the 60*, it was reading 7000RPM at about 3k, lol.

Yook only a few seconds to get to 80mph.


You mean to tell me that a SBC can't smoke the tires at 1500rpm in a car that weighs 2200lbs? I mean they were't "smoking" like a brake stand, but the ass-end went sideways. In fact the one time he did put it in second, I thought it was going to come around on us. 40/60 weight ratio FTW.

[ForcedFirebird]

His boat is over 1200hp.

A V8 Fiero weighs more like 2700 lbs or more, the lightest being 4 cyl cars at just over 2400 lbs. Since the engine is in the back the wheels are loaded on take off and traction tends to increase. The transmissions usually fail on take off where they tend to see the most abuse from a V8. If he has stock size tires on the car and a 4 spd or 5spd Getrag he may not have a problem with the transmission unless he beats on it excessively. Otherwise the later model fwd trannies or the 6 speed maybe in order.

most guys out in my area that mod fieros are middle aged. there are a few younger guys with em, but usualy they end up doing stupid stuff like putting 20s on it, or just light bolt ons.

we have some pretty crazy ones localy. one guy has a 4.9 caddy swap 86 gt, a 305 swapped 87, a turbo eco swap car, a 4.9 swapped 308 rebody, a turbo 3.8, and a few others. im surprised tho, no 3.4tdc, no 3400, and no l67. most guys seem to go small and turbo or just big, nothing inbetween

There's at least one example of a Fiero powered by each of the engines you mentioned as not, including some LS series engines as mentioned by someone else and currently the new LS4 and someone about done with a VW VR6 swap into one. There was also a kid installing twin Hyabusa engines in a Fiero. The Northstar swap is even more impressive than the small block. It's all on the Fiero forum, big blocks to and a near attempt at the BMW V12.

I did a TPI 350 swap that was a nice shocker but the weighty feel of the back end was bothersome to me.

He doesn't beat on it, believe me. I need to get his friend's name that made the fiberglass parts, you might have seen him on the boards - he owns about 6 Fiero's with all kinds of engine combinations (including the Northstar) and I know at least one has a 6 speed. Harold (with the 327) doesn't even have a PC, lol.

Really 2700lbs? That's surprising.

[Guest]

A fiero with a v8 is actually closer to 2900 lbs without driver. Especially teh GT like your machinist freind has.

But yea, man get him to make a kit, or at least offer the adapter plate for sale.
