There are two kids at my school who are interested in racing and here's what they got:
1967 Firebird w/ 327 Chevy, Hedman Headers, Flowmasters, no cats, and a 4 spd manual

I dont know too much about the mustang but this guy is extremely talented with mechanical stuff and cars. Right now he has the fiberglass body kit from Gone In 60 Seconds on it. He just swapped from a 3 speed to a 5 speed linked to an I6. Not sure of displacement but i think it's pretty beastly. From the way it sounds I'm sure he has headers and mufflers only.

Coming soon are SLP headers, custom tuned chip, and whatever else I can find cheap. Right now my cars all stock but what would it take for me to run with these guys?

 

a 350.

you had to know that was coming.

 

I was expecting it at least once.

 

I think the firebird will blow you away,, you might either run online with the stang or get your *** kicked.. The peanut cam and the auto are holding you back.. then your displacement isn;t helping either.

 

After bolt ons like intake, runners, headers, catback, chip, where do you think I would stand? And after that what about different rear gears, torque converter, pot and polish heads and camshaft?

 

your not an Iroc so the cai will definitely help, the camshaft will help you the most.. runners I really wouldn't bother with.. Headers help too..


I would need more specs on the stang but it would definitely help with the firebird.. Most likely the 68' bird will be you biggest problem cause it can rev to hell and back and its a v8. The stang you should get pretty hard off the line, but without and idea on how much power he is pushing I have no clue. Remeber they weigh as much as a foxbody.

 

so the mustang is a I6? if so i think you got him but i think the firebird will blow you out of the water.

 

Being an IROC has nothing to do with his intake. All TPI engines (and some V6s) had the over the radiator snorkel.

 

Haha... those I6 Mustangs are a joke. You'll take him no problem.

 

I thought firebirds had an airbox?

I know the procedures are very different when installing cold air.

with 190hp?

edit oh **** your right i thought they had 260hp... just make sure its a 6ixer

 

I thought the Mustang was a V6? It's an inline?

 

Nope, not a V6, they were a I6. Im not exactly sure when they started putting in the V6, but the I6 was in the 1967-1969 Firebird/Camaro/Mustangs fgor the base model for sure.

 

Keep in mind those cars were rated in gross terms, which means no accessories are attached to the engine and the test used simulated atmospheric conditions of 59° F and no humidity.

Net, on the other hand, used full exhaust and all accessories, 77°F and 32% humidity.

There's quite a difference between the two, sometimes increasing horsepower up to 25% from gross to net. There's no way to really convert gross to net, since different testing methods were used on almost every engine, but we can conclude that those engines actually made a lot less power if we were to use the net rating system in effect today.

The '68 Mustang had the option of a 115 HP I6 or a 120 HP I6. I'd guess that neither of them probably make over 100 HP based on the net rating system (completely stock that is). I can't say how much room for improvement there is by doing mods--I don't like Mustangs and I don't have any form of a six cylinder engine--but I can't imagine mods will make a huge difference.

 

I wish I could tell you more about the mustang but I just don't know anything else about. Except that the kid has a 427 sitting in his garage . He doesnt want to put it in because of gas prices. Needless to say I would be screwed... But I also know that he completely rebuilt the I6 with his dad. The whole family are just mechanical geniuses. I thought the bird would stomp me but wasnt sure about the stang. thanks for everyones input!

 

1) you will beat both cars
2) You could possibly beat the I6 mustang on foot.

ps:shift

 

I got a friend at school with a 68' stang I6. Things slow as hell, Im sure a suburban can beat it. I think you should beat those cars as well, I think you have a weight advantage on the bird. And unless the motor is rebuilt Im sure its a POS by now.

 

I misunderstood your first post, my mistake, you were correct
----------
Don't rag on suburbans.. my mom's '98 can move out

 

Im not really ragging on them, I know they can move pretty quick, my friends mom has an 02' suburban 2500 and it beat a 02' grand am se.

 

Well since the 67 firebird never came with the 327, i would geaus that it was rebuilt when it was put in.

 

326 CI

Maybe he was just generalizing. The 326 was a great motor as well, and not too uncommon.

 

Very true . I used to have a 65 Le Mans 326ci. Decent motor, not too bad. But I later put in a 389. But even if it is a true 327 chevy motor that doesnt mean it was rebuilt. I know alot of people just find junked cars or any motor they can find for a quick fix for their joe dirt cars, around here at least I see it alot.

 

Yeah, he said a Chevy 327. I don't know why anyone would ruin an extremely rare and classic car by dropping a non-original engine in it like that. I hope he meant the Poncho 326. Those things were pretty badass just like the Chevy 327.

 

The Mustang will be TOTAL annihilation unless something wierd is going on with it. If they are as bad as the 60s Camaro I6 motors (0-60 in 14 seconds), he probably won't have reached the 1/8th mark by the time you guys are finished. It will be "football field"-lengths, I tell you.

As for the Firebird, regardless of 326 or 327, if he can hook at all, I think you're in trouble there. If he had an auto it would be your victory, but with the 4 speed, I think he's got you. It could be close though. 60s smallblocks for the most part are pretty weak compared to modern smallblocks, even an LB9. The HP numbers are a lot higher, but they were using gross ratings and not net ratings, which makes a pretty decent difference.

 

if its an old stock, tired 327, you've got him. but a 327 in good tune is a fast small block,and can make alot of RPM.

 

The 327 has no special ability to rev high. The ability for an engine to rev high is in the valvetrain. The only truth to the 327 and high rpms is that it can sustain high rpms better than an identicaly prepared 350. Because of the shorter stroke it puts less strain on the rods. Two identically prepared motors a 327 and a 350 the 350 will make more power, and rev approx the same. The 327 is only better at high rpms in usually race applications. Therefore any joe 327 you see around town is not gonna be able to magically rev to 6,500 rpm.


But, I think there is a good chance you will beat him.

Also the ability to rev high doesn't mean that it's going to win you a race anyways, especially on the street where a good launch is everything(lower power bands). High revving engines such as autocrossers are built to sustain high engine speeds so their exit speed on turns will still be in the higher rpms where the engine is built to produce the power, among other things. Sorry kind of off topic.

Have fun taking them down.

 

Just cause the car might not have the original engine in it dosent mean the car is ruined. Personaly if i had an original 326 firebird i would take the motor out to put a built small block in it, so i could save the stock 326 incase i ever sold the car to get more money for it.

 

Ya thats a good idea, the 326 was a great motor, I had one in my Le Mans but I eventually did a GTO motor swap.

 

Alright, I'v got another car that needs to be thrown into the mix. This kid just got a 1981 Camaro Z28, completely stock. I asked him what kind of motor it had and he said" I dont know , i think a V6..." I didnt belive him beacause its a Z28. He seriously didnt know the difference between the two... What chances have I got with it?

 

If its a Z28 it was a 350, low compression but made 190hp, good torque tho. If it was a four speed it might be decent, but you should take him as long as your car is in good tune and you can drive.

 

a good one if you tell him the gas is the pedal on the left. sounds like he wouldnt know the difference.

You should be able to get him tho.

 

the 81 z28 should be good for high 15's stock, so it could be close with a stock lb9.

 

Ya, I didnt realize that his Formula was an auto till just now, if his Z is in good tune it will be a good race. Oh ya anomaly great avatar "NEXT THING YOU KNOW YOUR LIVING IN A VAN DOWN BY THE RIVER"

 

Cheese kake,i would like to know how your post magically sucked mine into it???????????

Check out post 25..

 

HAHA, yes I too thought this was very strange and at first I thought someone had cracked my account password. But if you read below it, it says that it was last updated by INWO , a MODERATOR, they have the ability to add to a persons post. They do this so that if someone basically just re-iterates what was already perviously said, they will add it to the original post, to add to continuity and flow of a thread, instead of having 30 posts that all basically say the same thing.

 

It does in my book, but that's only my opinion on the matter. Whatever floats your boat.
