ya but there runing a getrag that splits apart if you realy try to push it and the only standards that are realy fast are in pro stocks every one uses automatics every on from big block dragsters with powerglides down I am sure they can afford a good standard. The top fuel just use a cluch and slip it same with funy cars Plus we dont know if he put a stall converter in or what was done to the auto is that just stock we know the engine is not

I never began to dis the 3800. It's one of the world's best for my money. I said why dis a SBC? The fact that they are hard to cool in the back confines of a Fiero doesn't diminish it's stature. I myself looked at two nice examples in Chariton, Iowa, a couple weeks ago at a gathering. A 3800SC and a 350 SBC. Loved them both and would lose sleep trying to pick one. Well, the 3800 WAS red.

yes all three engines are cool 3800, SBC.and 4.3 I feel they all make good instal and all can make big power with a SC ,Turbo or NA

In fairness, back about 1996-1997 there was a guy from Mt Pocono Pennsylvania by the name of Pat Ciarcia (C&C Automotive) . He built a race only 400 CI small block chevy Fiero with a 400HP nitrous shot that ran a 10.38 second 1/4 mile. The car and story still show on V8 Archies website under customers cars.. This Fiero was a lightened gray notchback, with a full roll cage, tubbed rear wells with huge slicks and a modified TH-125H. The engine was heavily modified, the car was NOT street legal by a long shot, but Pat did post the time slip a while back. I cannot attest to the accuracy of the time slip but it was posted..
My preference has never been for the SBC swap as I believe that other engines will provide a better balance of economy, power, swap cost, handling, fit, reliability and drivability. The V8's can be built to be fast but if you can do the same with a 3800SC and be streetable then IMO its a better choice. Getting back on topic we don't see too many blazing fast 4.3L Fieros, so you might want to consider that.

You never will as long as a 350 bolts in the same.

^^^ ya but there arn't as meany 4.3 swaps as there are 3800's!! but as for fieroX doesn't DON have something
for you with that (427) hehe i can't wait to see that done!!! and ryan i have been in your car need another ride!!!! the 10.77 ride

but as for the 4.3 i think is would be cheaper to build than a 3800 i think that is you can build a decent 350 for $1500
what can you build a good 3800 for? and i mean built not a stock 3800

It is true the SBC bolts up just like a 4.3 but it is longer and can give you room issuse for the water pump and a few other thing on the front of the engine. It is true there hasnt been any realy fast 4.3 but no one has tried to make one fast they just keep it stock how fast is a stock 3800 NA engine lets compare apples to apples . I am sure you will get the same preformance from the 4.3 with the same mods

Hey I can head out to the track this weekend and snag a timeslip from a dragster, come back on here and say my car went 9.45. Show me a video. Plus i find it humorous he needs a 400 shot to beat me by .47 in the quarter mile at 1 less mph. Guess thats what it takes to get the 250 hp sbc down the track, haha.

Anyway, Im just saying, I prefer a 3800. I dont need a 400 shot, my car is totally street legal, I drive it to the track and back, I have a passenger seat, and it gets 24 mpg on the highway.

BTW im the only one that can

well as far as i see it a power adder is a power adder weather it be a tubo SC or nitrus the only real way to be fair is NA to NA no power adder then you can compare so FieroX what would your car run if it had no turbo and was NA it's the only way to compare apples to apples

THANK YOU!

Why is nitrous not a valid power adder and a turbo is? Just because you dont use nitrous doesnt mean its not a valid power adder..... Someone has been watching too much fast and furious eh?

ok then if its apples to apples, the V8 (that doesnt even exist anymore) can pull 2 spark plugs.

Look we dont care that it was a V8 or that he was using N2O. He is going to get beat, and till this day no one has ever seen this car go 10.30's. If he wants to setup a race lets make it happen. Do 3 passes back to back he should be up for it!

apples to apples would be 2 V6 a 3800 VS 4.3 with the same amount of mods stock against stock but you seem to imply the SBC V8 isnt as good as a 3800 V6 but the truth be told the 3800 needs a power adder to keep up do I think the 3800 is a great engine yes do i think the SBC is one to Yes I think the 4.3 can be a fast engine to I like N* to and the 3.4 DOHC and many other engines and they all can made to go fast

They are all good engines, and they all are apples to apples. Its called "do it". I hear guys all the time, "well if my 350 had a turbo it would be faster than yours". So I say "just do it then". Of course nobody ever does.

Correct me if I'm wrong, but the only thing apples to apples is NA with same size engine. Technically NA 3.8 and NA 4.3 isn't apples to apples, because the 4.3 is going to flow more air. That's a lot like adding FI to the 3800. But then when doing that, the 3800 is going to flow more air.

The only things he should be looking at when choosing an engine is ease of install, reliability, cost to get to x hp, fuel economy at the hp, and how common he wants his build to be. From what I've seen, if he wants a street driven car that runs decent numbers and gets decent fuel economy a 3800 is the way to go hands down. 4.3 will get you lower fuel economy, you'll have to pay more for a 4.3 turbo or sc than you would for the 3800sc, install is going to cost more and be harder with the 4.3, from what I've seen first hand and heard, the 3800 is more reliable.

No one said the 3800 was not a good engine instal but there is many that say a 4.3 is a bad install i disagree. a SC3800 is going to be around $1000 for the engine and 4.3 is about $500 .looking at the throtle body on the 96 and up 4.3 it has a restrictor in it on the throtle blade so just by removing it i bet you get another 30 HP you can get a street dreams adaptor and fly wheel with front motor mout and altantor mout for about $600 so you are looking at about $1100 so it is about the same money .I feel it just depends on what engine you want both are good engines . I also like you can go with the stock fuel injection or a Edelbrock intake and a Holly on the 4.3 and there is alot of after market stuff for the 4.3 if you wish to go that way

4.435@169

Incrementals are as follows

1.14 60'
2.96 330'
4.435@169 1/8


That's Conrad Scarry's small block turbo. The Fiero may be a favorable platform for the 3800, a very good balance, That doesn't mean that 3800s rule. I believe the fastest 3800 in any form is in the high 8 seconds in the 1/4. Making power and getting it down are not necessarily the same thing. Don't blame the SBC for a lack of fast Fieros. They are proven as much as you want to look for.

[This message has been edited by weaselbeak (edited 10-30-2008).]

ok i'm not looking to be as fast as ryan all though it would be nice. and as for fuel econo i don't care. i think a good 4.3 with
little things like port&polish,bigger cam,full roller rockers,10.5.1 compression,carb. i think it could run a good
12 all day long with a 5spd?

anyothere suggestions on times?

statistically speaking MOST SBC's struggle to get into the 12's. Mods and tuning are both usually lacking, but I was just using it as an example.

If it runs a 12 high in a RWD version, I wouldnt quite count on it running 12's in a fiero, but it should happen if you dont screw something up (like exhaust, intake, gearing)

^^ true

this is from the 1/4 mile list it said non member Ralph Degenhardt: 12.50@108mph NB (4.3 liter V6- cam, carb, Vortex heads, 4T40 auto)
to me this shows the 4.3 is a capable engine

that sounds good to me!!! but i would have to have a 5spd getrag with it though or a good 4spd

I am sure Archie or Street Dreams can hook you up with what you need fo a standard

I have 2 4spds and a 5spd

so what would you guys say would be the best to put behind a bad 3800 or 4.3???

prob a slosh box???

If 1/4 mile times are what your looking for the auto i would use one out of a early 90's car with a 4 banger it will more than likely have a lower drive ratio and a higher stall speed on the converter not as good on gas but it will be quicker

1/4 time is what i would be looking for yes. why not like one of the new trannys from a grand prix GTP or somthing like that

Yes a newer one will work i just like the ones that have hydraulic control over computer controled
this site will give you info on GM front wheel drive trans gearing and such

[This message has been edited by engine man (edited 11-12-2008).]

60e's are pansy asses compared to 65e's.

All i know is that geting the correct gearing is as important as having a lot of HP if your engin is made to come on hard at 2500 and run to 6500 but the trany isnt geared to let it get to 2500 easy enough it will be a pig out of the hole

I spoke to the owner of the car that went to wheatstock and impressed many. His engine was not a lot. Cam and head upgrade. the Trans was the trick. He's a Trans guy that knows what parts from one will fit and better another. He built his trans completely to do exactly what he wanted how he wanted it. The car was nothing short of Very Impressive to say the least. Here's the Link You read it.

MM sounds good pretty easy huh!!!!!

Did you make up your mind yet? I could take either one and be happy.

What are your priorities? Cost, ease of installation, support, 1/4 mile times, uniqueness, etc?

quote Originally posted by Hudini: Did you make up your mind yet? I could take either one and be happy. What are your priorities? Cost, ease of installation, support, 1/4 mile times, uniqueness, etc?

i think if i had the money i would do the 4.3 for this reasons uniqueness and try to make new record with it such as
1/4 mile times not trying to be the fastest like fierox lol just kidding but just something that would be compettive on the
street that some little honda or some punk it a shitstan aka mustang god it hurts to type that word!!! would look at me and say wanna
race and i would be like no i'll bet ya!!! and know that i could do it!!!!

maybe if i won the lotto i would try to keep up with ryan with a TC4.3!!!

[This message has been edited by BabyVet (edited 11-14-2008).]

all things being equal...
the stock CPI engine makes a little more torque sooner and the same HP sooner than the 3800
the 3800 since it makes its hp higher in the rpm range will probably have a higher top end

i don't know a lot about 3800 turbos or SCs but...
i know at least 300 guys making over 400 hp from a turbo 4.3 with pump gas and very few internal mods
stock block turbo 4.3s are running in the 10s with injectors, tuning and alky/water injection.
of course a 3.8 could do that as well but there isn't as much development out there for them
other than a few tuners like http://cartuning.ca/index3.php (*grins)

to me the 3800 is a better project because it bolts up to the tranny which allows funds to go to other
areas of the build and in the fiero community there area a lot of great examples.
