i HAVE proved that a healthy 305/T5 will whoop the doggie crap out of a 350/700-R4. i raced my friend's 1989 IROC with that "super combo" and i whooped his @$$ twice. he has the same mods as i do-the free ones and both cars were weighed on a certified scale. i love f-bodies, dosen't matter what combo they are, i love them. this guy just asked a simple question and suddenly its a "bar room brawl". if you look in ANY f-body history book it tells you the answers your looking for. there was never a 350/T5 f-body. there's no need in getting stoopid about it. it N-E-V-E-R happened, all of us fans dream of it but it didn't happen. im sure they were produced as test mules and thats how GM realized the T5 didn't have the stones to deal with the torque of the L98, hell it really cant handle the LB9. the reason it bothers me when people pick on the 305 TPI is because various GM literature says that the 305/T5 WAS the hot ticket for power. with the manual tranny you got the L98 cam which helped the "anemic" 305 a lot, along with the TPI you WERE the fear of Pusstangs everywhere! hell, it don't matter if i did outrun a 350, were all supposed to be on the same team anyway.

 

If you take a stock 305 5-Speed G92 and a 350 Auto G92 same year, same miles, the L98 is gonna win. Thats just the way it is. Mod for mod the 350 is always gonna be faster also. Sometimes slower cars beat cars that are supposed to be faster sometimes for many reasons.

 

I agree. As the old adage says "There is no replacement for displacement". Its all pretty simple 350=more HP, more TQ. The numbers dont lie. A better torque converter in the 700r4 would also make the race more on a level scale. And dont forget about the way people drive. You just may be a better racer than your friend is. Although the 305/T-5 combo is to be respected. In the world of 3rd gen f-bodys the 350 $ for $ will always come out on top.

 

Yeah, some cars are faster than others, even with the same exact drivetrain, straight off the showroom floor. So if you take a "fast" 305/t5 and a "slow" 350/a4, yes, I would beleive you could be faster.
I've driven plenty of 305/t5's and I'll tell you that they're no match for my 350. I can't speak for your specific car, but the 350/a4 was the "hot ticket".

 

I've got the best of both worlds . . .

 

It's statements like these that make me feel better I held out for the 350.

 

I'm doing that too.

 

ive raced 4 350's and havent lost to n e of them...2 were formulas from a dead dig to 100..were door to door out of the hole but to 100 i pulled a half car....the other 2 were at the same time (friends cars)....on the xpressway from about 60 to 120....i must have a really tight 305 because i beat 2002 gt mustangs and am door to door with cobras....hell even the ls1's only beat to 100 by a car

 

and so much of this is dependant on driver skill...

its not always the faster car that wins

 

I had 3 thirdgen's with 350 tpi's/auto and they all had different race times, some are just faster than others, and most people are right on here the faster car sometimes doesnt win. I personally raced a 305/5 speed and beat him by only 1 car length, and then i recently raced an lt1/6speed and i kept up. It all depends of the condtion of the car and the driver. But stock brand new thirdgen f-body's a 350/auto would most likely win versus a 305/5speed.

 

thank you f-crazy! i am so damn tired of all these ppl on this website calling me a liar because ive outrun some new Pusstangs and because i was able to outrun a 350. look at numbers, there isnt that big of power difference. besides look at the power lost through the auto tranny versus a 5-speed with experienced driver.

 

Lt1 6-speeds, l98's , mustang gt's

well...uh...I beat a ferrari...no, no it was a Mclaren! Yeah, it was a Mclaren.

 

How come no matter how many times this topic comes up, you always have a few people whos cars run so impossibly fast that it makes you crack a smile.

 

i have a 1989 IROC-Z 350 with the 700r4 and i raced 2 305's one of them was auto i gave it to him by about A car and a half..and the other was stick and i beat him by just as much...so i'm guessin with the 5 speed it depends on the driving..but i still beat him..but there are some lucky engines out there

 

I make it a point not to call anyone a liar. I have no respect for the newer 4.6L mustangs and I believe every word you say. However, my point is this:

1) The people you race against must be inexperienced.

2) $ for $ a 350 will always have more HP and more TQ. Its just the way it is.

3) A good tranny is the key for any automatic racer. Put yourself on a level playing field with a slightly modded 700r4 and you would lose. Again, that is just the way it is.

 

New 4.6 GTs (99-up) are somewhat respectable seeing has how they are normally low 14s to high 13s STOCK and some solid in the 13s, most 3rdgens just arent capable of that STOCK although some minus the TTA arent far off the mark. As for the LB9 vs L98 debate there is a possibility a healthy 305 5spd can win against a poorly tuned 350 or an inexperienced driver. I dont see many LB9s running decent numbers, but Im aware there are a few on the net running some good times but they arent stock either. Racing on the street is one thing, racing at the track is another but that wont make a difference if they guy in the L98 cant drive so I dont think what youre saying is far fetched you just havent run into an honest L98 with a capable driver....yet. Best way to find out whats what is to get slips, I didnt see ETs for both cars but there's a perfect way to back your claims up...

 

STOCK mustangs don't run low 14's....my first race i ever raced with my car i raced a 2000 mustang GT convertible and i ran 15.00 and it ran i think a 14.6 it was STOCK right out of the dealer...lol i have the time slip if you wanna see it..i can post it let me look for it...

 

stock mustang low 14's????

 

Im at sea level and yes the new styled stock GTs are capable of low 14s, some even HIGH 13s but I wouldnt consider that the norm. I myself raced one and he went 14.049 to my 14.021, after talking to the guy who was cool to BS with and looking at his car it was showroom stock. They have 260 hp and 5spds with a decent driver low 14s are possible. L98s have 245 hp, auto and are heavier and can manage 14.40s stock sometimes lower youre telling me the math is off that much?? LT1 cars have 275 hp, heavier and the autos and can clip off low 14s even high 13s. 95-98 4.6 GTs are dog *** weak, 99-up 4.6s are decent performers but nothing incredible. It pays to know your competition OR if you like Stangs like I do as well you follow up on their capabilities and know what SOME are capable of...

 

I stand corrected. A 260hp/5 speed can and will run low 14's. I havent seen one...but that doesnt mean they do not exist. I also am at sea level BTW.

 

Let me throw my two cents in. A properly driven LB9 5-speed car can beat a good running 350 auto. I have done it many times when my car was stock. If I compare my 1988 5.0 TPI with 215 HP to my wifes 1987 GTA 350 with 225 HP, I would win hand down every time. My car all stock would run 14.88 at 92 MPH, my wifes GTA would run 15.15 at 91 MPH. When you look at 1991 or 1992 LB9's with the duel cat setup and the 5 speed you have 230 HP and mid to low 14 second time slips if you can drive. While some 1991 - 1992 350's could run mid to low 14's the vast majority of the 1987 through 1989 350's could ony run mid to high 14's and some low 15's like my wifes GTA. While the 350 ussually has more power then the LB9 is also ussually has more weight and an auto that uses more power then the 5-speed. MY 305 LB9 weighs 3375 LBS my wifes GTA 3550 LBS.

The vast majority of LB9's are auto's which are slower then the 350 auto's but LB9's with sticks will give the 350's a run for their money.

 

For the poster of this topic... There were never any 350/T5 thirdgens huh?

You obviously are new to this car scene. There were 26 Firehawks built in 91 and 92. 1 in '91 and 25 in '92. So you are wrong on this one. They were released to the public, in fact I remember not too long ago a guy that is a police officer posted somthing about pulling over one of these majestic beauties just because he wanted to see it up close.

As for your racing prowess. Good kills. When you start getting all big-headed though, you should start racing people like me. I guarantee you won't beat my 350 A4 Iroc.
