BONE stock, i ran a 14.8. that was with ****ty tires that wouldn't grip for ****. was spinning all through first gear and right into second. 100k miles on the motor at that time, and the lady who owned it never took care of it, she just let it rot. now... she should be in the high 12's with the stock TC... i <3 my iroc-z

thats so cool! nice times i cant wait to have a L98 of my own soon.

u said consistent 14.5 and u then ran a 14.04 was that a typo and u meant 14.4?

SweetS10v8

100% stock L98, not even a K&N, only non stock item on the car was subframe connectors....14.25@95 with a 2.0 short time, with 145,000 miles on everything

TorchTA

JERRYWHO

times in sig.

but when stock low 14's still.

let me tell u, adding bigger rims and all kinda of suspension only helps with alot more power than a stock 350. so i am looking into motor mods now.

Damn, my stock car was slow. With full exhaust and a 2400 stall I ran a 14.36@96 on a 2.0 60ft.

JaysZee

I ran a 14.4 @ 95 with just K&N's and 135,000 miles. My 60's were in the 2.1's on crappy 245/50/16 Cooper Cobras.

My car went 13.2 @ 104 with the stock L98, ALL the bolt-ons, Longtube headers, full exhaust, 6-speed etc... (basically everything in my sig. EXCEPT the heads, cam, intake, and 5 extra cubes).

91TPI5.7

14.1 @98 2.01 60ft bad posi, pepboys futuras

now i ported the plenum and added slp runners with a lil port work to those

spring mods 2400 stall converter, new posi, shift kit, vette servo

summer mods headers, 1.6 rockers

MdFormula350

i am just glad i went from 94 trap speeds to 98 with just exhaust and a tune up. with timing adjustments i might hit 100 trap speeds. i hope to mid 13s with a stock engine.

D Stroy H8

Car is in sig. Have not run with Cutout and smooth bellows yet so disregard those mods. 14.4 2.0 60'

IROCThe5.7L

14.8@94mph, 2.2 60ft

(2.77 Gears)

Yellow87Bird

my lil 305 auto car went a 15.2 w/ a 2.2 60 ft and its got a cut out and a k&n

redtail2624

14.3 at 98 with a real crappy 2.3 60' cant hook up but anyway thats with a 305 not the l98

PhoenixFB350

5-speed?
I almost bought one of those but instead I got an IROC with an L98. I was giving LT1s a hard time bone stock, so somewhere north of 14.5, really pissed a few of them off too

speed88

Mine went 14.9 with a K&N, some wires and plugs. My buddies notchback did consitent 14.8's when it was stock. Plus he has 250,000+ km's on that motor. Both cars have the L98. I did some mild head and intake work on the stock components and went 14.3's. With better traction ( I had none!!), I think I could have gotten some 14.0's or 14.1's on a stock motor. With a good tc and some suspension mods I could have broken into the 13's easily with a stock L98. My friend with the notchback has since added a 2400 stall to his stock car and is getting 14.5's with bad 60's..no traction.

ThirdGenZ28 92

Near stock I ran 14.1 with a Flowmaster muffler, and a few other cheesey bolt ons. I added an SLP converter when I had the trans rebuilt and some other bolt ons and I ran a 13.521 on a 1.76 short time with drag radials.(stock manifolds, rear and untouched heads/TPI) My trap MPH is horrible I was having some top end bog before I stopped throwing $ at it. Hopefully once I get some $ and some time to spend on it I'll dust her off and see what she can do this year.

demonspeed

I wish I would have taken mine to the track. Anyone care to guess what a 123K mile 89 IROC L98 with Edelbrock headers and a Flowmaster catback would have done? Oh yeah... spent 2.77 rear too...

TPI-Formula350-

if it was a L98 i would guess around 14.7-14.8

demonspeed

ha, sweet. I used to think I had the fastest car back in high school. Sometimes ignorance is bliss, at least 4 years ago it was

I've learned a lot since I was 16. Now being almost 21, I can say I was pretty stupid then

redtail2624

yes that was with a 5 speed with the auto it would only do 14.7 at 94 so after the 5 speed swap it went down to my 14.3 at 98 mph.what a difference.

GTATransAM

I ran my car at 14.9 with absolutely no mods, nothing, exactly how it was when i bought it. Since then ive add SLP CAI, SLP Air Foil, gutted MAF, full tuneup, and just bought complete exhaust system, headers, cat-back, cat, with a cutout, and SFCs.

I dont know if ill take it to the track yet, but when i do go back, i wanna be comfortable i can hit 13s, cuz i dont to be taking it 2 hours away do to a few runs just to see i gained .1 sec or something, you know what i mean

Dustin Imports

14s stock works for me. rather start with a 14 second base car than a 17 sec turd car.

on drag radials could i hit high 13's? i got some new tires we will see how they hook up

SweetS10v8

I doubt it, what was your 60 ft time? maybe with drag radials and a torque converter you could pull a 13.9.

Or for the same $ buy a Nitrous kit and youll be mid 13s easy, possibly low 13s if you can hook it
