'91 z28 vs 89 mustang GT
Alright well i'm looking at buying this '91 z28 thats all stock except for a flowmaster exhaust system, my friend drives an '89 mustang GT 5 speed with flowmaster exhaust and an 'X' exhaust pipe installed on it. Would my new z28 hang with the mustang or would i be left seeing tailights, i'm pretty good with auto (know how to launch) and he's a pretty decent stick driver. Do i have a shot? by the way both engines are in good condition

Either way, you'll win. Those 5.0 mustangs stock only hit about mid 15's. Is the Z stick or auto?

an 89 5-speed stang with exhaust work and a decent driver will only hit a mid 15???? He'll give this Z a run for his $$$$

The auto ones at least. A freind of mine's 92 LX droptop ran a 13.9 with full exhaust, pulleys, a K+N and a 3.73 rear end. But the L98 is a strong engine... so i dunno.

i am not trying to offend anybody or anything, but it is nice to see a good debate over a race for once with two nicely powered cars. i swear all i ever read on this board are 305tbi's and 2.8 and 3.1 liter cars wondering if they can beat low end imports. again i am not trying to make anybody mad, so dont flame me. has anyone else noticed this?

Adams87Camaro, you're going to need intake work to keep up. Headers will also help. Stock 5.0s run mid 14's. If he can shift his 5 speed, he'll pull on you. Good luck!

That Mustang would only run a 14.8+. These cars ran 15.1s-15-2s stock. Don't listen to the mustang guys that have said that they were able to get then to run low 14s all stock(no exhaust mods,3.73 gears etc.). That after all is what an LT1 car (with 275HP- 50 more HP)will run with the average driver.
The 91 Z-28s w/the 350TPI & Auto combo is quicker than the 89 GT w/5 spd. I raced a bunch of them before I started to mod my car. I only lost to the ones with 3.73 gears -good traction and plenty of other mods. My car only has 2.77 gears.
So the answer to your question is : You get traction -You win!
P.S. -The reason everyone thinks Mustangs are so fast is because of all of the 305 TBI races against them that lost and the lack of 350 TPI cars on the scene.

Well let's see I've got a 350 TPI IROC..I've beaten my share of mustangs but also lost to my friend's mustang. He had a flowmaster exhaust with off road H pipes. And he advanced his timing. He spun for almost 6 seconds(saw it on the video from inside his car) and once those 2.83's got going in his mustang he passed me up and beat me by a half a fender. Now I did race him again and beat him by about 3 cars but still I was rather impressed by that showing. 5.0 5 speed mustangs aren't slow POS cars like alot of camaro owners think they are. Unless you've got a 350 don't even think about going after one of them unless you've got some serious mods. They're lighter and they have a better 5.0 motor..

Dont say they have a better 5.0 motor! *** , I hate because GM put a ton of bad 305 TPI peanut cammed cars out that every 305 is bad. I think mine is perfect and is the same as a 302 4.9 liter. Did you know the good ol 302s are actually 4.9 liters? I forgot the equation just do the math and you'll see ford rounded up. Anyway, yea mustangs are fast. GTs are the heaviest of them all but with a 5spd I guess he would run around 14.8. I ran a 93 GT 5spd with headers/exhaust/xpipe/pullies/cold intake/maybe a cam. it wasnt to quick, im not to sure what his 60ft was but he ran a 14.3 to my 14.4. I had a 2.3 60ft thats why he beat me, good race it was though. Just watch out for the Notchbacks, I plan on purchasing one soon within the next year or two, they are so light and so hard to find. Those are the cars that run 13.8 w/just an exhaust, no lies. Maybe a set of DRs but they are low 14s stock with a 5spd. The 5.7s came with 3.23s, just make sure u ease it out, Ive found that a stick shift car w/o any susp or dr components will lose in the 60ft to an auto. I can drive pretty good but the power is to much and 1st gears ratio are to high. btw, the 5 spd stangs had 3.08s or 3.23s, i think they were 3.23s

Thanks for your help guys, I raced this guy in my LG4 and off the line he could beat me bad but when we started racing from like 50 mph it was very close the whole way we quit at like 100 and his rear bumper was at my front bumper. Not sure what happened there maybe he didn't downshift fast enough, but the way this '91 z28 feels could give him a good run for his money, didn't the dual cat L98's get more horsepower too??

they do. ever look at the bore and stroke of their 302? you think that extra .1 liter is gonna give you the edge? the 302 has the 305 beat by far.

the 302 ford has two advantages over the gm 305 - bore and stroke . . . I used to have an 87 G92 IROC 5speed w/3.45's - mod to mod, hard to run with the mustang with the gm 305, it can be done, just not as easy as everyone here makes it seem. L98 cars don't all run low 14s either, even the SD cars have been know to run high 14/low 15 so I see it pretty close, but I am biased toward f-bodies . . .

i think a lot of people bs times on here. a lot of people get in there heads that an l98 is a low 14 second car and go run a high 14 or low 15 and are all sad. thirdgens didnt have outrageous power plants, thats just how it is.

the problem is the engines during that time were inconsistent..i've seen SD L98's run low 14's...then another stock SD L98 run high 14's a lot of factory freaks during that time..and a lot of really slow L98's
And there is NO question ford has a better 5.0(well 4.9 ). The 302 has the same bore as our L98 right? just a shorter stroke..i've owned a 302..in my 93 T-bird Lx 5.0...granted it wasn't a mustang..but i did little stuff...full exhaust pullies..cold air intake..and i was running with a lot of stangs and camaro's...anyway back to the topic here...the fact is with a decent driver that stang WILL give that Z28 a run...and possibly beat him..

laugh it up at our 305s all ya want. come on over and run mine. i have beat 2 l98 cars with authority. a 305/5speed and a L98/auto are as fast as one another. and stock for stock the mustang will always pull about 1-2 tenths. camaros normally run from 15.6-15.1. and stangs run about 15.4-14.9 but every car is different, many cars have had rough lives, and some are moded. cars are like people, there aren't 2 that are the same. some mustangs are fast, some are junk. there are alot of turd L98 cars out there because people beat the crap out of them. just like they do mustangs. my iroc was owned by an old guy who never drove it. it now only has 42,000 miles on it and i take good care of it too. it hauls compared to other TPI cars because it was taken care of. there is now way to tell who will win. so lets just let the mustang camaro debate die. both can be made into brutally fast cars. there is no way to tell accept to actually race. so quit BSing times on here and lets all be honest.

And L98s not all of them run low 14s. Only the G92 ones. I saw a L98 run 15.6 to my 15.5 in my old RS. I talked to the guy, said it needed a tuneup. These engines are 12 years old, its about quality when you choose these cars.

I have talked to some people who own the speed density l98s and they are a whole different type of beast then the mass air flow sensor, what i've heard is that typically mass air flow is better but with thirdgens the speed density seems to work better, and everyone i've talked to so far with the speed density l98s told me a tune up, K&N air filter and catback would put me in the low 14s no problem, i've seen it before is the speed density system that much better then the mass air flow?

Yeah, but my 302 will still be better than most any motor when it's finished.
It's going to be a DZ 302 replica. I'm anticipating it to be finished in about 6 months, provided I have funds. When I'm finished, that 'lil Chevy 302 is going to be a 450 horsepower 10k rpm high-revvin beast.
The Ford 302 is still better than a Chevy 305 big time. The 302 has the benefit of shorter stroke, which means higher RPM power, and can allow more valve diameter, due to the bigger bore (as opposed to the 305s smaller bore). I think the Ford 5.0 HO is better than any 305.
Oh your 305 has 230 horsepower and 300 ft-lbs? Well 87-92, the 5.0 had 225 horsepower and 300 ft-lbs. Why wouldn't the Mustang run low 14s too? They are lighter than your G92 Iroc.
My point, it takes all these fancy RPO codes and a special package to still make the same power as a 302. That power came standard in the Ford cars.
Oh, by the way...you can find Notchback 5.0s everywhere, I see ads in the autotrader with 6 for sale for 3 grand a piece. Retired cop cars with new paint jobs.

why does every hate the 305, you say it's a bad motor but it's the same damn block as your 350, the only difference is that GM purposely made it slower. Think about it, if they made the 305 as fast as it could be then it would've outsold the 350 in mass numbers. They had to make it slower in order to sell the upgraded package with the 350. But all you need is a cam and some heads, maybe and little intake work and your beating the stock 350's with ease.
#27
The 305 block is not the same block as a 350. The only similarities that a 305 has with a 350 is block SIZE and stroke.
Some 305s can hang well, but their smaller bore doesn't allow bigger valves which is a key factor in making horsepower. The 302 does have a bigger bore, and a shorter stroke, which allows for more upper end power & rpms. The 305 is a bad design, as is any SBC design. It's not the best motor ever made. It's just simplified, easy to make powerful, and inexpensive.
The 305 doesn't deserve any credit for being a good motor. I've spent thousands of dollars into my 305 to make it fast. I just ended up taking all the stuff out, because it's bad for gas.
The 302 SBC I'm building for my car is going to be bad on gas due to higher rpms, but I'm not going to drive it everyday.
The 305 is not a race motor. Small bore and long stroke aren't the way to go. The 305 is good for gas mileage, just what GM intended it to be. Also good on emissions, do you actually think GM would have created it if there weren't stricter emissions laws and the gas crisis of the 70s? No, they would have the raw power of a big block sitting in our thirdgens, not a wimpy 305. Ford did it right, the 302 is a excellent idea, they've perfected it since the olden days in the 60s.

My 88 L98 Formula went 14.30s with only a Flowtech muffler. Not all MAF cars are dogs. And I have seen SD L98 cars do 14.10s basically stock as well.
Yeah, the 302 is a better motor than the 305. Period.
------------------
L98, 3.27 9-bolt, Hooker shorty headers, custom 2.5inch Y-pipe, no cat, 3inch 2chamber flowmaster, JET AFPR, Ported MAF, Best ET: 13.86 @100mph. 1.99 60'
17 inch ROH "ZS" wheels. 17x8.5(front) and 17x9.5 (rear). Firestone Firehawk SZ50s. 245/45/zr17s and 275/40/zr17s. T56
On the way... Radar Blue 89 Formula, T56, Ram Jet 430, Ram Air, 17inch ROHs.

I dont know how this turned into a 305 vs 350 debate, but doesnt it always? Anyway, the L98 should win, but like said earlier by a fellow thirdgener every car is different. With my 305 tpi auto I have beat a 94-97--? mustang 5 speed at the track. Some do run 15+, but then again I have seen many stock 89-93 stangs run mid 14's. Give it a try and then you'll know if you have to go spend some more $$ to beat him next time.
good luck

And he can drive stick pretty dam good actually. He spun more than me at the start however(i had no wheel spin). Which I think kinda ruined the race for him. He did stay with me for a while but once top end power came into effect I took over the race.

My dads 91 LX 5.0 pulled a 13.72 with just gears and pulleys. A 5.0 with a stick, and a good driver should be low 14s, so he would probably have you. But the Mustang driver has to launch his car, which Mustangs are notoriously bad at. If he spins, or bogs at all you should take him.

A 3.2x geared L98, especially a 90-92 SD car will run with the 5spd Stangs anyday of the week if not beat it. Mod for mod you two will be darn close. I'd be betting on the 91Z if it's in tune and you don't blow the launch. Driver and state of tune of the car are the reasons for the any argument here. Both are capable of mid 14s at least bone stock. If your 90-92 L98 runs slower than that you're doing something wrong...

Don't mean to be interjecting on a chevy vs. chevy argument, but there's less than a 50 lb. difference in the weight of a 5.0 notch and 5.0 lx hatchback. The GT's weigh a little more, but not so much so that it's going to slow the car way down. Depending on factory gearing options (3.08 vs. 2.73) and transmission type, I've seen bone stock 5.0's run anywhere from low 14's to low 16's...it's all in the driver and state of tune.

These cars are old. Ive seen L98's go low 14's stock and I seen some go 15's stock. I think its all about how the engine was treated it's whole life.

Nic's right, the notchs weigh about 60 pounds less and it's all over the rear wheels.
The 305 should get worse mileage than a 302. Also due to the shorter stroke of the 302 it should have a longer life in it.

Thats alot of reading.
Anyway, I think the stang will win.
Anybody that says the stock '88+ 5-speed 5.0 'stangs could'nt run low-mid 14's is blowing smoke.

Engine: 305 TPI

It breaks down like this. The 302 from its inception in the 60’s was developed as a performance engine. The 305 when it debuted in the mid 70’s was designed to be an economical, gas saving alternative to the bigger motors at the time. Therefore the 302 was built stronger with more of an “eye towards performance” and will respond to mods better than the 305.
Now, that being said, that doesn’t mean the 305 is a bad motor, or that a 305 5spd thirdgen can’t beat a 5.0 stang. The intent behind developing the R6P or G92 performance package for the 305 TPI 5spd, was to make it more competitive with LX 5.0 Mustangs. That’s why the horsepower and torque numbers are the same. Of course the reduced weight of the Mustang gives it an edge. So a stock for stock, a Stang might have a 2-3 tenths advantage over a 305 Formula or Z and a 350 Formula or Z will run just about even with it.
Here’s an “average” comparison:
305 TPI 5spd..14.7-15.0
350 TPI auto…14.4-14.7
302 HO 5spd..14.4-14.7
I know this is a little off the(ancient) topic, but the 305 bashing tends to get annoying.

I read all of that, and found out I responded a year ago also!!! The 5.7 and 5.0 Mustangs make for great runs, the 5.0 5-speed Camaros do also, but do seem to be slightly slower! Any car can be made fast, and it just takes more to get a 305 to go fast. But there is a limit with the 305s which is much slower than the 302 limit!
