hey i just got a 84 camaro i was told it was a irock but might just be a rs it is a 305 with carter 650 carb elderbrock intake 5 speed tranny and that special austrailion rear with 3.43 gears or somethin around that ration what do u think i could run in 1/4 mile

 

o **** frogot about the cam it has a .502 cam i was told and what kind of power do u think it would put down

 

If its an lg4 those made 155 hp, and ran mid 16's. If it is a l69 ho it has 190 hp and will run mid 15's on average. This one will have the dual snorkle air cleaner w/ 5.0 decals.

 

If it's an 84, its not an Iroc or an RS. 1985 was the first year for the IROC. I think 86 was the first year for the RS, but don't quote me. If its the ausi-9bolt, you probably mean 3.45s.

If your car does have all that, and only that (meaning, power robbing non HO factory exhaust), and you can drive it pretty good, you should do low 15's high 14's. With full exhaust, maybe mid-low 14's.

Get some nice headers and a catback or at least a cutout, and take it to the track.

 

yeah i plan to get some headers soon but got some other things first like carpet

 

o yeah just read a mag and they broght back the irocks in 85 so cant be one so its a z28 then if that maks any differents
and it is a l69 plus them mods and u still thint it will b that slow

 

With those mods you should be low 15's, maybe alittle better depending on the tune.

 

Not knowing of what was ever done with that motor it isnt very accurate on what 1/4 times you will run, first the carb on there isnt stock, im not sure of the stock cam specs, but possibly the motor had a swap, still im not sure, i guess run it down the track and let us know, you may have something you dont know in that 305.

 

yeah it has a .502 cam in it its a big cam alot bigger than stock and a 650 carb stock is like 450 or 500 yeah when i get it on the road thats the first place im going

 

Word of warning there young guy. That tranny was designed to handle about half the power that engine is now putting out. Take it easy on the burn outs and second gear shifts or you'll be seeing most of the gears roll out from under the car one day. Gets expensive fast. Sounds like a fun car!

 

hold on a second, did you say the mag said they brought BACK the iroc in 85'?? because thats the year they were CREATED. so bringing it back is impossible lol.

 

You have a Sport Coupe with a LG4 and some mods. I'd say it'll run hi 15's.

IROC's started in the '70's. It wasn't until '85 that it was a model.

 

Those aren't 'mods' they're downgrades. The engine would have been originally equipped with a computer controlled qjet that would certainly outperform (and outflow) an old Carter. It would also have had a computer controlled distributor (and it would be worth checking to ensure that it has been swapped for a mechanical dist with vacuum advance).

The LG4 would be identified by an "H" in the eighth place in the VIN. If it was originally an L69 the only remaining pieces left might be the larger exhaust and the electric fan.

 

If you have an lg4, take it out and use it as a boat anchor cuz thats all its good for.

 

its a l69 and how do u figure there not mods cause that makes no sense at all and if u no about the tbi u would no that the tbi chokes the motor up so a carb gives it more power and some more potential so i dont see what ur talkin about

 

L69 was a carbed 305, not a TBI. It could flow 800+cfm. You put a 650 cfm carb...you do the math. Computer controlled distributor is better than a vacuum advance distributor.

You sound like a kid who has been talking to an old timer. Fuel injection bad, carb good.

 

Thats why carbs still come stock on our cars today..

wait

wuuuuuuuuuut

 

Guys lets not mock him now, if theres nuthin to be said but negative feedback toward the thread just dont reply back at all, cause then its just gonna be another bickering argument. And i dont think he was talking about his l69 motor being tbi, i have no idea where that came from, but tbi isnt a very good flowing injection setup stock anyway, and ive driven the tbi cars, and 2 carbed third gens, i dont see a difference between the 2 until the tbi reaches higher rpm then the carb feels a little better. And we dont even know this dude, so dont judge him when we dont even know him. He didnt know much about the car in the first place, so what he has is probably what he has to live with and learn.

 

He was being sarcastic about the fuel injection bad, carb good.


Anyway, to the OP...FFS it's spell Iroc. Also, I don't think the 9-bolts came in 84, I thought they started in '85. It sounds like you have a Frankenstein of a car.

 

So was I. hahah.

 

 

I'm sorry, I don't usually post unless I have something at least moderately positive to add but sometimes grammar and lack of punctuation makes my eyes bleed

the rear is out of a 89 trans am acuatly the whole drive train is come to find out so to be honest couldnt tell u if its a lg4 or l69 i dont even know how to check and just found out the motor trans and rear was from a 89 trans am cause i ran into the guy again and he said something about it but there basicly the same thing and my only point was that guy said puttin a carb on it was bad which is dumb cause y would 80% of the dreag racers have carbs if there no good

 

As everyone else is saying, IROCs came out in 1985, and ended in 1990.

 

Oh and id be guessing high 14's or really low 15's.

 

If the motor came out of an 89 it'd be neither, it'd be a LO3. Basically a boat anchor You're looking at low 15's with a 20mph tail wind.

 

is there any way to tell if its a lo3

 

Not anymore. You could check the cylinder heads casting numbers to determine whether they're swirl ports, check for one or two piece rms and maybe pull a pushrod to see if it's a roller motor. Other than that all bets are off as to what is actually inside and whether or not it was installed in that motor at the factory.

Neither the LO3 nor the LG4 are completely without merit. Both have potential to become spirited motors with bolt-on mods. I would stop well short of any machine work to a 305 though.

 

just 2 correct ya here 85 was the first yr for the iroc's and 87 was the first yr for the RS but if im correct it was only avalible in cali
