I was wondering what does a stock 4.9 with an auto or stick run in a fiero, ( at the most with a rockcrawl chip)? I'd be more interested in this install if I had an idea on performance times.
The first (and only) time we ran the Finale with the 4.9 we ran a 14.81@ ~100 mph. BUT, we have a problem. When Rockcrawl did the chip, the code on our transmission was unreadable and he used the most common gear ratio in a '93 Deville, a 2.73 (or thereabouts) to program the chip. When we ran it on the strip, we would hit the rev limiter and the car would not shift unless Chris got out of the throttle first, then he could go again. We've since had the car on the dyno and from that were able to calculate the true final drive ratio is a 2.97. Rockcrawl is even now reprogramming us a new chip. The dyno showed our engine to be making good HP and we should be in the high 13's. I'm HOPING for a 13.89, but I'll be satisfied with anything under 14.
I've driven a lot of quick cars in my years and this car certainly feels like an honest 13 second car to me if we don't have to get out of the throttle two times every pass down the strip.

PS: Forgot to say this has the 4T60E transmission and is bone stock except for an MSD 6A and is in excellent tune.

I need to know this information too before I do this swap. I dont wanna put a motor in my car if i'm gonna be running 14's I want at least a 13.x 1/4 mile. It just sounds better to say 13 rather than 14 know what i mean.

Not yet, trying to go for the 1st time this saturday, worst case my 1st run will be on the 14th at St. Thomas
Got any pics of your new install?

I thought Rockcrawl, before he modded his 4.9, was in the high 13s? I've always thought the 4.9 was a mid to high 13 second car. The torque down low makes it a real good 1/8th mile car, do they seem to run out of breath at the end of the 1/4?
I think I am forced to agree with the Punisher.. My 4.9/auto bone stock is running consistent 15.1 That's with tires that were not hooking up well and a load of crap in the trunk. Also, unlike most 4.9s my car has a full exhaust with a CAT. So with new tires I think I could get to high 14s.
But I don't think you are going to get to the 13s with a bone stock 4.9

I will be running a Carbed 5spd Notchie with TRUE Dual Exhaust and I hope to be in the 13's Will be able to post when I get it done.

I agree with the punisher here. Rock crawl’s 13.9 was with a manual tranny and some mod's. I'm willing to put money down the a stock auto 4.9 will run at best 14.6 (I'm in the 14.7's now). Every time I drive it at the track I seem to get faster however I really don't think I'll break 14.6 without doing some mods. I hope to be the 1st person to show what a stock 4.9 / auto will run on a 100 shot of nitrous. Right now I'm waiting on a few required items (imho) before I spray it (MSD Ignition, MSD Retard & Upgraded fuel pump, the stock Fiero pump is only good up 250 or so by other people’s observations)
I have driven and been in many 4.9's incuding Rockcrawls modded 4.9. The 4.9 is great for the light to light low end grunt. With the caddy transmission, using caddy a caddy torque converter, you will be going down the highway at 80 mph and 2000 rpm. The combo is set up for factory cruising not for drag racing. I am sure a stock 4.9 with a standard transmission would drop a second in the 1/4. Even without a caddy trans/torque converter it would drop into a consistant mid to high 14's. Most people who pay for swaps are looking for reliability not a mix and match to get it down the track to be quick enough to satisfy some punk(s) with thier expections. So yes. . . there are many things you can do to the 4.9 to increase the 1/4 mile performance but changing from stock factory takes away from the daily driver reliabilty.
I would say if you want a drag car then don't go 4.9. But my wife has well over 250 1/4 mile passes on her 4.9 while other 3800 sc have broken before reaching what she is producing on the track. Also sbc 350 are complaining about traction or tranies or I could have done better if I tried.......
So please, the stock engine bashing is really lame, my brothers stock sbc in his auto firebird does 16.5 sec in the 1/4 mile. A stock auto V6 fiero is mid 16 sec but light to light is not a challange for a civic at times according to some. So why is a stock 200 hp V8 auto a problem if it produces times that a 200 hp engine should. Light to light it will have no problem even if the honda has NOS.
We have proven the 4.9 to put-out mid 300 hp with a 12.2 ET quarter mile and are now surprisingly in the top 10 of fieros on the 1/4 surpasing many other known "better" engines according to some.
Anyways I have been rambling, What I am saying is why compare a stock automatic 4.9 V8 to a modified whatever. There are many stock 350's not pushing out 200 hp that thier owners are more than happy with.
The 4.9 is an engine that as it revs it looses power, which is really a different sensation that most people are use to, and must be driven in to feel and appreciate the right-off-the-line feeling.
Stock 4.9 and stock chip, 4T60E, 2.73FD, BF Goodrich 245-55-17 with car at 2990 with me in it. 60 ft 1.896 1/8 9.290@ 73.6mph 1/4 14.694@ 90.172mph
There is slight tire spin, so with good rubber, maybe could find another tenth or so.
In the 16 passes down the track, I have run against Mustangs, Camaros and Firebirds that were mid-high 13 second cars, and in every case, beat them to the 1/8 mile (that includes a New Corba R) . After that, it is over.
This is why the 4.9 is such a great street combo. It has the power where it counts in light to light racing.

Who cares -------I like the way it sounds!!!!! No 4 banger or v-6 will ever sound this good!!!!!!! If you are reading this and like the way a 4cyl sounds with a poopcan exhaust then you wouldn't understand----Those of us born a few years back appreciate the sound of an American v-8. My 2.8 was tired and the caddy will give me good gas mileage plenty of power and nice reliability for a good price and it will always sound wonderful to my ears.

As most will tell you, the 4.9 may not be the best choice if you have the dragstrip in mind. However, it's damn hard to beat (even in stock form) when dueling in light to light challenges.
go with what you like, but where else can you get such an affordable swap that is a pleasure to cruise in and is within striking distance of a stock C5 Corvette, which runs a 13.63 1/4 mile.
Boy it seems like everytime I here anything about 4.9 times I always see some type of troll hijack 4.9 threads..... That troll knows who he is.... I will not say names.
anyway I think a stock 4.9 with the 4t60E will do mid 14s, Now a carburated stickshift 4.9 in my guess might do a high 13s, Only why I say carburated is because your allowed to play with the timming advance with softer springs meaning your advancing the timing faster including several other things.... I won't turn this into a carb vs pfi thread......
Now for the price of a 4.9 swap is good and running mid 14s But with a bit of work you can easily get this engines ETA time faster ..... There's sooo much you can do proformance wise and im talking with only bolt ons. And it's been proven from fuel pfi swaps and carburated swaps.
The problem is ppl expect to drop a 4.9 in there fiero with no mods and expect to hit 13s...... Power requires money and work.

It seems to me that the Caddy auto is ok for modded 4.9's with higher hp to work with, but, for a stock Caddy engine, the gearing is not favourable for 1/4 mi.
Just my opinion, but I don't think I'd be using the Caddy tranny. I think I'd be looking for a 4 gear auto like an Olds or GTP tranny, otherwise a manual tranny if I was looking to make the most of the 4.9 on the quarter mile.
The rpm range of the engine seems to call for on OD gear for highway, ruling out a 4 speed Muncie and leaving the 5 speed Gehtrag as a good possibility if you want stick.
I'd sooner try a better suited 1/4 mi. tranny before writing off the stock engine's potential.

Hmm you are probably talking about me. Sorry but how is my post a trolling post? I spoke the truth. Every stock 4.9 auto owner here who has posted times has posted times of either very high 14's or low 15's.
And I dont' care what you "think" a stock 4.9 with 4t60E will do, cause its been proven it will NOT do a mid 14 EVEN WITH SLICKS!!!!! Keep thinking that all you want. It still wont' change the fact that it won't run mid 14's on a stock setup.
cause its been proven it will NOT do a mid 14 EVEN WITH SLICKS!!!!!
Actually I'm closing in on mid 14 right (14.67@91, If you recall 3 weeks ago 14.89@89 was my best, without changing anything other than my driving I have dropped 2 10th and I'm sure I can pull 1 more out of it) now on street tires, every time I have run it down the track I pull a fatser ET. I'm still learning to launch it just right. I suspect that the 4.9 with Auto is really capable of 14.5.
BTW Punisher you stoll my avatar from another forum? I use the will Ferrell one on another site.

Case closed.
Did you even read my post ?
And the sad truth is.... a person that hijacks every post that invovled a 4.9 is a troll in my book..... Sorry that I hurt your feeling I was actually trying to be nice by not naming any names you already named yourself so there. And it is very possible to run mid 14s with a pfi 4t60e setup.... I had to take time out to laugh when you said that it couldn't do mid 14s on slicks because alot of the caddy trannies is geared where you barely squeek the tires..... So answer this.... Why would a car that barely squeeks the tires need slicks ? There actually a bit heavier.
oh well im done with you...... When you claimed that you could get a 2.8.... Up to what? 200hp for only $500bucks?... then when everyone questioned you your only remark was nitrous on a tired 2.8 I just shook my head.
So 14s is good but there's alot more to build on with bolt ons alone and im not talking about using nitrous on a tired 4.9

RUN THE 100 SHOT , YOU WILL KICK ASS!!
I talked to PBJ today... you need the nitrous. no candy ass 50 shot.. 100 or nothing!!!

I was going to step up to 100 in 25 Shot increments. However now that I have everything inbound (Upgraded Fuel pump, MSD Ignition and Retard box, Hobbs switch) I'm skipping the 25, 50 and 75 Shot and going directly to 100

No you didnt' hurt my feelings. You can't possibly hurt my feelings. Yea I am so glad you didnt' name names cause its not like noone knew who you were talking about because you were being so discreet about it But I guess you are right. It is possible to run mid 14's on a stock 4.9 and auto tranny as Linenoise is now proving with his 14.6 but I am glad you got a chuckle out of it. Laughter is the best medicine and I think you could use quite a bit to be honest.
Also you are barking up the wrong tree. Why dont' you ask Linenoise why he is using slicks with his 4.9 swap? he is the one that ran a 14.8 with the use of the slicks. I think you will be able to find your answer with him, not me. Boohya. You just got pwn3d!!!

Shake your head all you want just dont' break your neck. Yup thats right. I did 200 hp on a "tired" 2.8. I would think thats such a nice feat on a "tired" 2.8 don't you? And its kind of funny. That "tired" 2.8 was hella faster then many of the 4.9 swaps here. Thats impressive I would think for a "tired" old 2.8 Lets see a 14.1 at 91 mph with an auto tranny. With a 8.8 1/8th mile at 76 mph? Lets see here. That "tired" old 2.8 is still .5 faster then the fastest 4.9 here that has posted times and still even faster mph wise too!! Not bad for just a "tired" 2.8
I might have bought my car with a "tired" 2.8 but at least I didn't swap out one tired engine for another tired engine.

So 14s is good but there's alot more to build on with bolt ons alone and im not talking about using nitrous on a tired 4.9
Show me 4 bolt ons made by aftermarket companies for the 4.9 without including nitrous because you know, nitrous doesn't count.
And it goes to show you how ignorant you are. I never said my 2.8 was tired. Others did. Unless of course you consider a 20k mile 2.8 tired. But if that makes my engine tired what does that make your 50k mile 4.9?
I see you live in Florida. I know someone with a tired 2.8 that has no problem meeting you for a freindly race. his tired 2.8 vs your not tired 4.9 swap.
PM with what general area you live in and maybe something can be setup.
Lets see if you are willing to back up any of that big 4.9 talk you spew.
And more ignorance from you again. I never said that I ran a 100 shot. Where did you get that number? Where did you read that and who said it? Because I sure never did.
I ran a 70 shot. So I guess technically I had in the area of 210 hp or so. but thats not important.
You are being called out!!!!! Are you willing to step up to the challenge???
