As I understand it, (and somebody please correct me if I'm wrong), the car in the video was not done for a customer, but purchased specifically to show off Archie's new 6 speed swap kit. Is that right?

It would make sense to me in an advertising sense then, for Archie to build an "ultimate fiero". Something that runs 10's reliably, 6 speed V8, built with his kit. Something he can show off at the different car shows and get more customers. The question then is why not.... I don't think it's a cost issue, but a reliability issue. There just isn't a transverse tranny that can take more than 400hp reliably without blowing itself up. Having the "ultimate fiero" eat transmissions would be a PR nightmare.

With a good dyno tune the engine could easily pick up 20+hp. Thats what dynos are for, tuning. Its a benefit that you get to see your power at the wheels. Adjusting a carb by ear is not an accurate tuning method.




so go tune it then.
not your job you say? well its not Archies either.
its cute y'all think he's some kind of Fiero god, but c'mon, he is just a guy installing V8 into Fieros. and not even his own V8's. you bring him a sloppy smoke belching V8 - you are gonna get a Fiero that belches smoke. He has no magic "anti-smoke" potion he rubs on. but, it is cute you think he can.....

When we judge a swap, we should look at the HP number but we should also look at the cost per HP. If 230 or 250 HP is the number, why bother with a V8? The turbo 3.4L dyno video that I posted last week showed 397 ft lbs of torque and 336 RWHP from a 3.4L. Take a look.
[youtube] http://www.youtube.com/watc...gV4oA[/youtube]Tioga runs mid 13's in the 1/4 mile with this 3.4L engine in a Camaro. 3800SC's in Fieros usually do even better. I believe that Don Kraus 3800 has already hit the 10's. Nothing against the http://www.youtube.com/watch?v=EaqYdpgV4oAV8 in a Fiero but why use one?

Because that's what the customer wants.

WTF are you talking about? I stated an observation. Where the hell are you comming from exactly? The "smoke" is black meaning that its running very RICH. Its not blue meaning its burning oil. This can be fixed by leaning out the carb. Do some homework.

Tuning can certainly be done. But this wasn't a test and tune session. With as many people as were waiting to get their turn on the dyno, I doubt many (if any) were tuning and running multiple times. Only 1 run means you get what you rolled in with - perfectly tuned or not.

Granted. Archie said he went to another dyno and got 20 more hp, did he tune to get more hp or was he still running pig rich? He had the WB02 in the exhaust pipe, curious to see what the readings were.

I am coming from a place that knows that not all SBC's are the same, and just becauise "Archie" installs them, they dont magicly transform. and, more so - that installation is NOT tuning. just because Archie installs it, it does not magicly tune itself. a transmission adapter plate will not make a SBC run stoich. no homework required. Archie is just a guy installing SBC's in Fiero's. that is it. he is not a magical being. he cannot magicly transform a 185 hp TBI 350 into a 400 HP 377. your Fiero will contain the motor you provided or requested. that is it.

but, if you want to go and do his tuning for him, go right ahead. I am sure the customers would LOVE a free dyno tuning. especially from someone who does homework.

just to note, the classic, high revving 377 is made from a 400 block and 350 crank. You can also make a 377 using a standard bore 350 with a 400 crank. Now that yeilds a 383 with a 0.030 overbore, but standard bore engines make it a 377. Now you may instantly think, hey, 0.030 on a 350 gives 5 more cubes, wouldnt that be a 378? no because remember your increasing the stroke still and that 0.030 will give you almost another cube, and a 383 is a rounded up number anyway.

So standard bore 350 block with 400 crank, 377
400 block with 350 crank, 377


but either way, as said earlier, Archie installs what the customer wants. its not archies fault the car put down about 230 to the wheels, its the customers car and motor. if the cutomer wanted a 500hp SBC, then it would have made 500hp. but now that everything set up, down the line if the guy wants a motor with more power, he can put it in in a few hours

Again you are taking things out of context and comparing apples to oranges. The Turbo 3.4L was on racing gas and the boost was cranked for the dyno run. The car does NOT drive daily with that much power. (As stated by the owner of the car.) The V-8 in the Fiero was a standard run-of-the-mill V-8. If you want to compare engines set up specifically for power, What are your comments on the LS1 that dyno'd 508hp in a Fiero??? What did it cost to put the turbo in the Firebird and how much was the cost for the custom heads he used? A brand new Crate LM1 with 265hp is only $1800. So please find out the cost of that turbo 3.4L and lets compare cost vs. power properly.

How much did you spend on YOUR turbo 3.4L? If I recall it was somewhere around $5000, right?
My V-8 brand new off-the-shelf was only $4000.
So you spent $20 per HP and I spent $11.27 per HP. (Even if I include the cost of the install kit it's still only $14.27 per HP.)
So since you go by cost per HP as a guideline, How much have you spent so far on the 3800SC?
Will you actually dyno this swap? Or will you just post G-tech 0-60 times and claim an extra 50hp as well?

With 336 rwhp and it only runs mid 13's???? I have 309 rwhp and I run low 12's. So why spend all that time and money on a turbo V-6 when a N/A crate V-8 will actually produce faster times with no mods to the engine?

If Don hit 10's before he sold the car, he did not note it in the 1/4 mile thread. Actually the only 10-second cars on the list are V-8's. FieroX should be in the 10's but he seems to kill transaxles before getting there. (I am hoping FieroX will be able to get a transaxle to hold all the power he's making and get some decent mid 10-second runs in.)
