hey i have an 88 iroc-z with the l98. my cousin just got 95 stang with the 5.0. his ratings are 215hp and 300tq (is what he told me) im sure you know about the l98, so who do you think would win in a drag? any opinions welcome....thanx

iroc-zman17

o and both cars are bone stock

89IrocZ350TPI

Here is what I know


95 GT 215 hp/285 lb ft 14.9@93 mph
88 Iroc L98 230 hp 330 lb fy 14.5@95 mph


These are what the cars are rated at. If your car is in good tune you should edge him out.

That mustang is one of the slowest in the history of the 302 motor. They're very lucky to see high 14s, and that's only with a stick. An auto will see mid 15s on average.

Don't worry about it if it's stock.

nick418

go kick some butt.

Ray87Z

I don't know, if you've got a single cat 2.77 geared L98 and he's got a 5spd you may be in for trouble. You need to practice and make sure you can nail the launch repeatedly, you'll want to take advantage of your superior low end and not waste it spinning... If he's got an auto you should win handily all things being equal.

25thmustang

High 14s for him is probably a decent guess. Always expect him to run slightly faster than you think he should, so your prepared for him! I never underestimate other cars!

hot92z

If i could take one with an Lb9 there is no reason you shouldnt with an L98 if its running good

89IrocZ350TPI

Ok...Did I miss something? Anyway you will win if you know how to drive. Id only worry if he had a 99+ GT.

stu

I think you did, because that quote is from another thread.

89IrocZ350TPI

Whats it doing in here

87TPI350KID

Remember that not all 95 mustangs are stock either. Although 'slow' to start, they still have good old pushrod power under the hood.

EDIT:
Still, i know that 5.0 liter cars still run stong with tons of miles on them whereas our sbc can feel the difference

ShiftyCapone

iTrader: (7)

Eh... That is debatable . I would say there is equal high mileage SBC's running the same ET's as they did when stock.

lilbowilson

iTrader: (2)

That just depends on how well the engine has been treated. If the rings are worn out then so has your hp. I also driven high milage stangs and they were slugs also. It dosn't matter if you have forged parts (like the 5.0) or cast if compressions is lost THEN YOU FEEL THE DIFFERANCE IN BOTH!

i am more than sure you will beat him,if he is a stick or not i feel you should win,i have done similar races when the cars were much newer and NO 94/95 could come close stock for stock we beat the 87-93s as well the only problem back then we had to guess at what would work not much available from the aftermarket but we ran strong and had the pony cars payin close attention to us..slowest L98s were 14.5 fastest with minimal mods was 13.1 fully modded was 11.40-12.70
a friend bought a 95 new 5spd etc. bone stock it ran 15.3 he got heads,cam(e303)t-body&spacer,full exhaust w/headers,on m&h racemasters it ran 13.3s same mods to the 87-93 you would be in the 12s all day

94-95 5.0 with exhaust mods... stick

versus my 89 L98 with full exhaust and 2800 stall... 3.27 gears
145K miles on the clock. street tires to street tires

my 13.99 at near 100 (traps in right lane arent workin right) to his 15.2 at 94mph. 2-3 weeks later i seen him go 14.7 at 94.x.

i crushed him off the launch... his 60 foot was over 2.0 i dont remember exactly what it was. mine was 1.88. LOL

u out launch him and your gonna put some lengths on him. from a roll it will be closer. stock for stock, the L98 in good condition will pull it. stock L98s should trap 95-97mph. 95 5.0 should do 93-94ish

urbanhunter44

iTrader: (3)

lol who the hell told you that one

my car with 150k, bone stock except for a catback trapped 100 mph.. that's exactly where it should have been if it had 15k on it.

all motors will feel wear if they're abused and not taken care of. i've driven fords and chevys alike that were total dogs because of neglect.. and i've driven high mileage examples of each that still hauled the same *** they did when they came outta the factory.

TBI92Camaro

My 5.0/5 speed bone stock on bald, dry rotted tires ran consistant 9.3's/9.4's with 228k miles on it.....thats pretty damn good. Shoulda ran that factory

25thmustang

I dont really understand all of this, but it sound slike your saying the Fbodies dominated the Mustangs in the thirdgen eras, and the slowest ones ran 14.5s (L98s)... I would have to disagree totally, and if anything the fox body Mustang more or less had a reputation in the 80s and 90s, and the Fbodies had to play catch up, and the slowest ones were probably in the high 14s low 15s, and Im sure some ragged out ones maybe even slower! And your friends car with the right owner might have gone much faster as well!

urbanhunter44

iTrader: (3)

seems to me the foxes always ran right with L98 cars, or the G92 LB9s from 91-92. But other than that the thirdgen was behind usually.

89IrocZ350TPI

Man you got a really good launch.

92droptopws6

iTrader: (10)

well i speak from experience,there were guys getting blown away by 5.0s all day but my click of friends had them very cautious of racing us we had the correct mods done and we were winning many races lost a few too but non the less they rarely wanted to race us unless they had fully modded cars this was done in houston back in the 90s.
25th i hope you did not misundertand my post and to clarify
87-95 we raced f-bods and fox bods only and depending on the mods done we would win most of the races we raced(my crew)now there were MANY f-bod guys that would lose hard core cause they did not know how to tune,drive or to race cars in their class.i mean the most lethal car back then and even now is a stock sounding,nitrous fed,sticky tired car with suspension work. the shame of it all was the 5.0 guy that was beating up on 305/700r4 z28s and braggin about it till the 5.7 z28 showed up or my 5.7, 5spd on tire

Orr89RocZ

iTrader: (20)

stock for stock, a 5.0 stick car ran well with the later L98 cars, as did the G92 5speed Lb9s. the l98 cars i believe were a tad bit quicker. but cuz of the gearin disadvantage cuz its an auto, the L98 really would shine with a stick.

but once bolt ons hit, stangs kinda pulled away

89IrocZ350TPI

82-86 was dominated by the mustang GT's. 87-89 would make for pretty much a drivers race. The 90-92 speed density cars definitly give the Camaro the advantage but it was still close. Too bad they couldnt make a strong five speed to put behind the 5.7.

87TPI350KID

Wow, sorry about the 5.0 vs sbc debate on loosing power, obviously any engine can loose power but I would have though forged interals would help. Anyway, long live the chevy.

25thmustang

Well in each scenario its different. If I speak from my experience I have never seen a mild Fbody car ever copme close to mine or my dads cars, and they took built motors to run in the 12s with us. DO I stick by that as the "norm" or how it always is, of course not. I know what cars can and cant do...

But the fact of the matter is, in the grand scheme of things, on the streets in the 80s the GNs and 5.0 Mustangs more or less dominated... One reason for this, Fbodies had so many crap motors, whereas ALL 5.0 Mustangs got the same power. The 5.0 stick Mustangs were right there as fast as the L98s, but the 305 cars were slower (not the 5-speed G92s)... This is one reason the Mustang heads up racing sanctions formed, the 5.0 aftermaket boomed, and the fox bodies becamse one of the most well known vehicles.

Now I am NOT saying the Fbodies sucked, were junk, or were slower. Thats not the case at all, and as you said where you were the Fbodies dominated. But I can assure you, here in the Tri-State area in the 80s and 90s the Fox Bodies were definately more potent than the Fbodies. The sad things is, even today the Fox Bodies out number the thirdgen cars by the thousands, which is actually kind of sad!

no prob 25th,as i have given you props in the past on your combo,you have many valid points in this post we sort-of hijacked i have had many 5.0 stangs, made them faster sold them,i worked for lawrence conley workin on gn's for a long time always had f-bodies in my camp..you are correct about the 5.0's dominating the streets due to the available aftermarket items and EVERY ONE wanted a stick and the 5.0 was the BEST bang for the buck,90lx sedan 5.0,5spd,no power w/ac for 10,000 and dealers like tommie vaughn ford selling and financing n2o,blowers,upgrades the gt40 cars they sold man ford was into puttin the power out on the street FINANCED upgrades they laid the smack down HARD....as i stated before my click had the knowledge and helped represent the f-bodies but that was 8 of us compared to how many?baad odds!i bag on fords quite a bit only cause i have built many fast ones,hell i bag on anything if it deserves it including my SLOW assd RS outside but my 2 Lt1's represent very well

Orr89RocZ

iTrader: (20)

i take it, a mild fbody as in a thirdgen? then yes you are correct... most 350 cars will only go about 100-103 with full bolt ons and a tune. fox bodies do have the advantage cuz the light weight

25thmustang

Thats what I meant, as in my area the similarly modded LT1 cars are running similar times and the LS1s... well nevermind, LOL! I actually know a good amount of the Fbody owners in my area, and most are cool guys, I just havent seen one yet that has made me want to sell the Mustang and spend the money on a thirdgen! Maybe some day my mind will change, and it would be cool if it did, change it up a bit, but until then... I like going fast for pennies on the dollar!

Orr89RocZ

iTrader: (20)

well nothing wrong with a thirdgen 350 car that goes carb. for cheap you'll be faster than a 5.0 with full bolt ons.

how well does the GT40/cobra 5.0 intake flow compared to TPI? TPI will only support 4500-5000rpms or so on a 350. LT1's are just L98's with slightly better cam and LT1 short runner intake. thats how they get the 300hp, and respond well to bolt ons like exhaust because the RPM capability is there with the LT1 intake. TPI is limited. i'm guessin the 5.0 intake can support power to 5500rpms or so, so the bolt ons really wake the car up

urbanhunter44

iTrader: (3)

Lol did you know that LT1 heads outflow L98s by quite a bit? L98s IIRC flow about 180ish on the intake at .500, LT1s flow about 215. That combined with a far superior intake and slightly larger cam give them about 305 flywheel hp.

not trying to talk crap or anything, just letting you know that it's more than a bad intake that the l98 was given.

89IrocZ350TPI

Well no **** lol. LT1 is more advanced than the L98. Just like the LS1 is more advanced than the LT1. Now we can even order LS2's and LS7's. Performance was not very alive in the 80's. Thats why there was or SS camaro in the 80s i guess.

87TPI350KID

If GM would have designed an intake around the 350 instead of the 305 and stuck the same lift/duration cam that cam in the lt1s, thirdgens would be a little more potent on the track. TPI cars do make for good DD's though. 2nd gears still sucks *****.

lilbowilson

iTrader: (2)

HUH?

2nd gears still sucks *****.

It doesn't suck on my car but I did have mine built to handle 700hp

25thmustang

Well in this day and age if you have to go carb to go fast, I personally wlould look somewhere else. Carbs arent what I would want in a daily driver...

Yes our intakes will easily support the RPMs, and aftermarket ones are pretty cheap (youd cry if you knew what I spent on my intake and TB) as well! Not to mention the cars by design are good track cars, have strong parts from the factory, and the motors can rev and make good power... not a bad choice for a race/street car!

Orr89RocZ

iTrader: (20)

vette l98 heads flow about 200cfm.. irons are about 190's... LT1's i figured were just above that.

the cam has alot more lift so it helps out alot. doesnt take much tho to get a L98 to 300hp.

87TPI350KID

Crank horsepower i assume. Accually it takes a pretty big chunk of change, sticking with tpi that is.

Orr89RocZ

iTrader: (20)

yeah 300crank hp is pretty easy to obtain

TBI92Camaro

They flow good....port the lower and itll easily support 375+HP N/A.....Good, cheap, intake for the buck. and then you have the whole aftermarket intakes...including the uber-badass BBK SS-I intake :drool:

You can snag a used Cobra/GT40/Explorer upper/lower intake for 200-250 all day long......port the lower some and its a good bolt on....of course heads and cam will ocmpliment further. I know my buddy Jusitn has the Trickflow top end package on his car and it was good enough for a 12.3 pass in an SN95 car (much heavier than my Fox Body) Im cure in my car it would have been good for a 11 second pass.....N/A

rx7speed

the rings,block, bearing and so forth are all the same though.

87TPI350KID

I've given up street racing every fox body. They run 13's with gears, filter and catback Then add intake, headers and a good driver and they run low 13's all day long

z28z34man

the 5.0 fox may be more modable but we have handling, looks, and besides the rare duke no 4 cylinders

25thmustang

Well looks are subjective, I will say you have handeling, but the 5.0 fox bodies have nothing to do with the 4 bangers. And by looking on Ebay there were more 5.0s built than almost all thirdgens (I was looking for a 350 car)! To each his own, everyone has different goals, and picks their own way to get there!

Nate86

Ford sold (and still sells) those Mustangs like hotcakes. Never understood that one, but then again, I do see a lot of chicks driving pony cars around these parts.

Most of the fox-bodied 5.0s are driven by hot-rodders though. One of my friends from work has a 5.0 ('91 if I'm not mistaken) and it ran a 9 flat at our local 1/8th mile. Not too shabby for an intake and a few other bolt ons.

z28z34man

i have nothing against the fox stang the 5.0 can definitely be midily built cheaper than than the tpi

i just like the looks of the third gen better

and i have driven the 4 cylinder auto stang and it was the slowest vehicle i have ever driven and that is an accomplishment i have driven a 4 cylinder caravan

89IrocZ350TPI

I read on that old irocz.com site that for every 1 Iroc made there were 9 mustangs. Not sure where these numbers came from.............

Not in the year 1987 that was the only year ever that camaros out sold mustangs. It was like over 200,000 units sold because that was the year GM brought back the 350 in our cars. Read it in some article somewhere.

25thmustang

The 4cyl cars do suck, I own one (the faster style with a stick though) and can attest to it being slower than most vehicles! The only thing with the foxs that was nice is they sold a lot of V8s and every one had the same power (the 305 cars in a lot of years werent great)! Unless you had an auto, you had a good platform to run fast (in a straight line of course) which is why the sold like hot cakes!

Orr89RocZ

iTrader: (20)

whats your average 5.0 fox weigh in at? LX's are lighter than GT's. i'm guessin 3000-3200lbs for the foxes

while the fbodies were 3400-3500lbs or so.

theres a possibility of 300-400+lb difference and thats huge. thats one of the main reasons why bolt on foxes are so fast. and the fact that the 350 fbodies didnt have a 5 speed hurts alot. 700r4 gearin is not at all optimal for 1/4 mile.

what do full bolt on/exhaust 5.0's dyno? 250-260? with the proper tune i can see that out of a 305 car with all the mods. 350 cars should dyno that or more.
