here it is... remeber the motor is stock, stock manifolds, original cat factory tailpipe and over 100K on the clock... never had a valve cover off or the intake for that matter... the mods are in the sig... 305 t-5...

13.78 @ 96mph
1.84 60ft
8.75 @78mph 1/8

I am gonna have this slip framed...

track and weather conditions were perfect... beautiful day...

I got my 13sec time slip...

zroc

You got a 305 into the 13s with gears and a K&N?

Dude, that is really really fast. I will need to see a slip to believe it. You ran a 1.84 60 foot!!!???? You beat professional drivers!

What tires are you running? 1.84 out of an unmoded 305 is great. With 2.73s I pulll 1.9x's at best. What RPM are you dropping the hammer? Lastly does the exhuast have a hole in the Y-pipe that is bypassin gthe back end of the exhuast? Great times so many questions.

i am throwin up the on that one. no way will a stock 305 run a high 13 or even close with so few mods. if your car runs 13's my 85 toyota tercel 4wd wagon with it's 1.5L engine can run 15s

heh

He forgot to mention the car weights 1,300lbs

hah..i dunno bout that time. when i go to the track this week to sears point I'm hoping for a extremely low 14. I find that hard to believe.

He must be leaving out the slicks and the 5k clutch dump, cuz there is no way that a 5spd 305 is cutting a 1.84 on street tires any other way. Sure, I've done it on street tires, but i have an A4 and a big converter, torque multiplication and ease of control of the power go a long way in my case. Have to be one hell of a driver to duplicate my launch with a clutch and no boots.

Other than that though, i can believe it. He's got me by 3mph at the 1/8 which is right what he'd need to be doing to pull those couple extra tenths. And i have no problem believing that a lighter coupe, with a 5 spd and 3.73s would have me by more than a few tenths either.

There have been more than a few 305 5 spd cars running 13s with practically nothing over the years, they are freaks for sure, but they are out there. Off the top of my head, Matt98SS (previously Matt 921LE 91B4C C3P0 8675309) went 13.7 with just about nothing in the 1LE, then went mid 12s with an ATI blower on top of that. And look at Rob P's 92 vert, ran 14.1 @ 96 with just a ported intake, including the stock 2 1/4" cat and only 3.08 gears. If you don't think -400lbs and 3.73s and a 3" cat are worth 3 tenths, then

Sorry guys. Maybe he's lying. But then again, maybe he just has one of the freaks. I wouldn't throw the flag on it just because you're jealous though. You remind me of the guys who swear i must have a 350 to do what i do, again,

trust me i know 305s can run good. i ran a 14.82 @ 93mph in hot weather with the stock torque converter and 3.23 gears. the only mods i have are a hollow cat, flowmaster muffler, headers, gutted MAF, and ported plenum amd 214/224 cam. it idles pretty rough and has nothing below 2000rpm. my best 60ft is a 2.19 with no tire spin. i am sure that in cooler weather it would run a 14.7 at least. and this winter when i port my intake base and install my converter i am shootin for low 14s. i know a 14.8 is kinda pathetic but my combo is a bit mismatched right now, i need a better intake base and a higher stall converter. now i know a 5speed car is gonna be a little quicker, but holy cow man, 13s?? that just does not add up in my opinion.

:hail: just wait till summer the phat trans am will show you whats up

yeah thats 1meanz has a rust bucket and runs low 17's i'v seen it. Yeah maybe if it was hill jacked or maybe jeromejacked.

who can I e-mail the time slip to??? street tires??? yup... bfg drag radials.... she hooked like a friggin' mother... the 60 foot time blew my friggin mind... usually its in the 1.95 area... I yanked out everything that wasn't bolted down and the rear seats were already out it had about a 1/2 tank of fuel... best previous time was 14.03@95... the air was perfect... normally she runs 14.20s...

I've got the slip, if you wanna call me a liar I'm offended but you have the right to your opinion...

zroc

hrmm ill get 13s with just headers and a nice 60ft, dond doubt the 305.

I will always doubt that a stock 305 can outrun a stock LT1.

I've seen many stock LT1s run 13.7, and i've seen a few go faster than that. In fact, the only LT1s i usually see that can't crack 13s stock are the occasional 2.73 A4 vert or cars driven by complete fools. Not everyone races on poorly prepped tracks at the top of mountains in bad air you know.

I still don't understand why this is so hard for some of you to believe. I went 14.7 @ 93.6 just by swapping to big outlet exhaust manifolds and dual cats in a 2.73 geared barge. Went 14.38 @ 95 with 3.23s and headers, and IMO the gears are what made all the difference. Now factor in a few hundred pounds less weight, a 5 speed for less parasitic loss in the driveline, 3.73s and drag radials on a ***** to the wall launch.

I don't know what it will take to convince some of you people that it is possible. I guess some people just have to be haters...

it's hard for me to believe because I've never seen a stock L98 f-body run 13s, so seeing a stock LB9 f-body run 13s is hard to swallow.

Rare, but not impossible. Congrats on the good timeslip.

Good Run.

I can Belive it. Lighten it up, drive it like an animal. It just has to be one of the "one out of ten" cars. that the heads actually CC the same in every chamber.

I've run 14.7 and 92.95mph in my stock lb9 5spd. the motor and trans are fairly well whooped in it, and the car's over 3500lbs.
It's a 305 tpi/5spd, 3.45 gears.

I Purposely launch very easy on it. and have cut 2.09 60'ers, running 35psi on vrated tires.

If i pulled out all the stops launced that sucker on the MT sportsmans, dump the clutch at 4500rpm strip everything but the shifter out i think 14.3's aren't out of the questioin.


But... i digress. I think it's certainly possible,... seen stranger things.

With all the years you've been here you've never seen any of the 13 second L98s. Where have you been, under a rock? I can think of more than a few 14.1 and lower L98 cars with basically nothing done to them. I can't think of specific names off teh top of my head (but i think Rob P's 89 RS vert had a stock L98 running like 13.8 before the ZZ4, or how about fly89GTA, it didn't have much done on the L98 and the previous owner had 13s, etc) And a stock L98 car has the BIG disadvantage of a stock converter holding it down. A 5 spd car with 3.73s and sticky tires can go with reckless abandon right off the line and makes damn near the same power as an L98.

I said I haven't seen it. I didn't say I haven't read about it.

i believe every word of it....mine ran a 14.8 with an easy launch 2.25 three holes in my "n10" fubar plugs wires a worn out throw out bearing and an intermittant 7 cylinder problem.....

with a full tune up and it running properly and a stiff launch i can defenetly see a low 14....

you have my vote for "305 of the month" zroc lol

and ed's last post summed it all up

It was horse****, and btw dont the 6 speeds come with 3.42s like my car??? So a 280hp car and 345 lbs/ft of torque beat me by 1 and 1/2 cars...I know L98s that couldnt keep up that well...btw my headers put 2mph on my car. Oh yea arent they running EFI too??? That car shoulda wooped me down, not all 305s are peanut cams thanks.

And P.S. my buddy has a stock L98 G92 89 I bet he runs a 14.3 w/gutted MAF and k&n, and some timing...with the free mods and some susp hell grab 13.9 or better no doubt.

Anyone notice its alot faster than almost all the TBI cars?



I believe him, its possible. Take a look at Tim Burgess' car and what he has ran over time.

I'm well aware of that. My 15 second 5 speed GTA has the good cam just like yours.

Nice times! With an all stock engine and just bolt ons, and a race weight of 3575 with driver my 305 5SP with 3.45 gears ran a 13.85 at 99.29 with a 1.93 60 ft. Now my 305 is running 13.50's with 118,000 miles 8.8 to 1 compression and the mods listed in my sig. Not all 305 are slugs.

Your a nutslap,man you are talking about a massivley modified motor.Just because the bottom end is stock doenst meen you have a stock 305 so quit advertising you are running 13's on a "stock" 305.

A friend of mine has a '91 Z28 1LE L98, and back when it was "stock" (by SCCA Solo II standards, which meant just cat-back exhaust and a K&N drop-in), it ran a high 13.6 or 13.7 ... with over 100K on the odometer ... auto, original engine, never been cracked open. My girlfriend's ex drove the car, and he also drove her '96 Z28 1LE (also SCCA Solo II "stock") to a 13.41 the same night.

If that L98 could break into the 13s, I don't see why a 305 TPI with drag radials, some interior gutting, a few mods, good driving, and optimal conditions could do it, too.

Reread the post. He stated he ran 13.85 with just bolt ons, thats not a "massively modified motor."

Read better. He hadn't touched head or cam or intake base when he ran that 13.85.

And jinx on Greasemonkey...

Crap! Haven't been jinxed in probably 10 years....

Ed and everyone with the good words, thank you...

I am pretty proud of what the car and I were able to do on a seriously limited budjet...

I have been racing this car for three years and experience is definately a factor... I held the rpm's at about 3800 rpm and let the clutch slip just a little off the line to keep the wee O 5 in its happy place... its definately an art launching a manual trans car... it felt awsome... and I gave it no mercy through the run...

by the way... anyone got a wc t-5 core I can rebuild for a reasonable price... I need one pretty bad... pm me ... yes I will check the classifieds...

zroc

Zroc. congrats on the great run.

Good run zroc.
If I ever get finished with the 305 in my B4C I am looking forward to running it at the track. The owner before me ran 14.2 in the car so I hope to get into the 13 with it..

I ran 13.851 in my 92 Z l98, it had nitto's on it, air foil, MSD 6al K&N air filters and Hotchkis suspension, the best 60' I could get was 1.93, if I tried to launch any harder it would wheel hop really bad.
