350hp N/A Fiero, pics!

[IsaacHayes]

Fieros aren't as light as everyone thinks. They are light by todays cars but not what you'd expect from a small two seater fiberglass car. I'd love one with an LS2 in it!

There's a way to modify the tach to read for a V8. I think changing capacitor out is all that's needed, but it may be easier to mod a 4cyl gauge cluster tach to v8 than v6, but I don't know for sure I haven't seen how they are setup.

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.

V8 Archie as well as Street Dreams offers adaptor plates for the small block chevy to transaxle attachment and possibly KFG in Canada if they're still in buisness so technically with a little creativity you can put one of these in the fwd cars if you're not afraid the front end will be snatched off. The 4.9 caddi motor would be much easier though.

There is a tach fix thread on the Fiero forum also. Not much you can't find as far as what's needed for the chevy swap.

I say at least 2700 lbs on the V8 swap because some 84 and possibly 85 base model cars weighed less than 2500 lbs and the base V8 swap is said to add about 150 lbs or so to the car. My 84 SE was under 2500 on the title the current 86 SE 2719 and the 85 GT 2900 both V6 cars.

The Miata is the real pig in disguise at well over 3000

V8 fieros are teh sex! Nice cars........now stop before I start another project!

[85maro]

Heh, I know. Makes me want to get a fiero.

getting a fiero just for the fact of putting a v8 in it is not a good idea. Most v6 fieros like the 3800 sc swap would run circles around 95% of all v8 fieros. hell my 60 degree v6 fiero would beat 99% of all v8 fieros out there and I just have a dinky turbo.

V8 fieros for the most part are slow gas guzzling turds. Most run in the mid to upper 13's in the qtr mile. Hell I witnessed 3 fieros in daytona last year with v8's ranging from 330-355 crank hp all dynoing less then 240 at the wheels. I think the highest was 240 with the other two around 230 and 238 at the wheels. Funny because one claimed 412 hp before he dynoed and he only put down 238 hp. I laughed my ass off.

After more discussion with him, he bought the adapter plate that converts the small corperate pattern to the 90* pattern (works either direction). The 327 was a 350hp crate motor with 0 miles he got at a swap meet. He already knows about the resistor mod fo the tach, but doesn't really care.

He is finishing up the front clip and Corvette tail light mod, then the 327 is comming out for higher compression Air Flow Research aluminum heads, and I'm helping him do the Vortech roller lifter retro-fit (requires drilling/tapping the block), and a big roller cam. He's going to be shedding some weight on the motor while adding power/efficiency and should be even sicker when tha new motor is finished.

He is old-school and knows his stuff, the 1200hp boat I mentioned is a 150mph drag boat (502SBB 2 stage nitrous), and is just using his skills on this project. Again he's in his 60's and like to play with his toys, like a kid. I keep trying to talk him into giving me his old 2.8 that cam out of the car when it had 30k miles on it -- it's on the loft right next to his ultra-light plane, lol.

He didn't buy it to put a V8 in it, just happened - and he's a sucker for a good deal. His Harley was fully custom bike that was unfinished by the previous owner - all the parts were still in the wrapper/box, just unassembled (now is 3 motors and 2 paint jobs later) it still looks like it was built yesterday. He's in Daytona until Mon, and is hoping to pick up some Corvette seats while looking for a deal on the heads.


I'll get some more pics of the bodywork next week when it's out of the shop.

[ForcedFirebird]

Well, he ended up going with something a little different...












Of course he's not finished with the front end mod yet, and he already found a new one he likes better (full-tilt front end - seemless hood), still doing the Corvette round tail lights...

[IsaacHayes]

I would of left the tail stock, looks great stock but oh well. What's the specs on those heads?

Not sure of all the details, he paid ~$1000/ea for them at the swap meet from a Crane Cams truck. They are CNC ported with the 1.98/2.02 valves, and have a 64cc chamber (down from the current 70cc). They are CNC ported, what does that tell you? He's shaving 60-70lbs off the car or more, and is planning on a mean cam.

I agree with you on the tail lights, I also told him I like the flip-up headlights better, but to each his own, lol.

[IsaacHayes]

Yeah I like flip ups too for some reason. Whats those carbs?

would he be interested in a freindly run once his new mods are on?

Are you in DelRay?! Both his and my shops are in Deerfield Beach.

Right now the crate motor is supposed to be 375hp, but he claims more like 350. I'm trying to talk him into a turbo, lol.

Are you sure about the valve sizes there? stock performance small blocks use 1.94/1.50 or 2.02/1.60 valves and aftermarket goes up to 2.05 and 2.08 for the intake and 2.10 (but the valve was moved over slightly and requires offset rockers) and the exhaust goes up to 1.65. I have seen bigger valves but there where on SB2 head which looks more like a big block than small block.

From the picture view that doesn't appear to be right, they don't look close enough in size and I think they would have to be splayed like the V6 aluminum head's valves for there to be room enough for that size combination, I saw a set of heads in a book I have that have a thin partition between the larger than normal valve seats so there wasn't much room for excessive overlap.

Meanwhile a twin-turbo carbuerated longitudinal V8 just showed up on the Fiero forum. Fiero owners are a special group of people aren't they. I believe it's the outstanding location of the engine and size of the car that drives the madness to create.
