The 2000 Z28.....Unless its a standard and the kid cant shift....He should be low 13s so it wont be a blow out...

its a auto. and 2000 z28 is my car.. 88 is my brothers

Everyone on here knows the L98 and Vortec SBC's are superior to the LSx. I heard the gen I SBC's "potential" for speed forced GM to discontinue production for public safety concerns. GM then developed a safer platform (ie LSx family).

But honestly make sure your brother doesn't have the might 305 that has the potential to run 9's.

We're just all lucky that the camelhumps and RV cams went out of style or else we'd all be pushing the sound barrier by now.

86White_T/A305

If both cars launch well it will be a close race down the track with the 00 z28 taking the w on the topend.

There are plenty of 14 second cars out there with that killer combination... Watch out! LOL

good stuff, made me lol

I confess I'm one of those closet believers that the SBC has hundreds of locked up horses I'm just an exhaust and CAI away from time travel homi!

Man, what is it with you LS guys? Talk about annoying.

Because our engines make so much power, we spin the world in reverse when we hit wide open throttle.

Seriously... I think someone is just jelly they spend a buttload of money on retrofitting a motor that could have been built using a SBC for less money.

Wanna bet otherwise?

Aren't they? Not to mention having absolutely no lives whatsoever, having to lurk around the theoretical section of a non LS1 board because they have nothing better, not to mention nobody better, to do...

Agreed. Funny thing is, these are the idiots that will sling that very word towards people, meanwhile they openly admit to "street racing" their LS1's and almost getting caught by the police in another thread. Doesn't say much for their credibility, does it...

A vortec 350 with all of the bolt-ons and 4.10's should be capable of 12's on the right tire. Stock L98's should be running 13.7's all day long with bolt-ons on street tires unless you live at some ungodly elevation.

My 260hp B-body LT1 knocked down 13.3's on POS 10yr old Kuhmo Ecsta Supra's. Race weight is 3750lbs in that run.


Stock LS1 4th gen vs bolt-on vortec 350 thirdgen should be VERY close. As in no winner determined.

I've shocked the hell out of stock LS1's with my car.

Bolt-on LS1 > Bolt-on LT1 > Bolt-on L98. Bolt-on LS1s can trap near 106-109mph. A Bolt-on L98 would be lucky to hit 100mph.

ZONES89RS

My L98 I had with 4.10s, performer rpm air gap, 1 3/4 headers, 750 carb, T5 Trans went 13.87 at 101 with a 1.8 60 foot. That was leaving soft. Was scared to leave hard, and the rear broke the next pass but you know there would have been more in it if the rear would have held for a hard launch. Engine had 150k miles.

LOL That is funny.

I am glad I put the summit racing sticker on my car, I dropped 8/10th of a second by doing that... LOL

I'm waiting to get called out from across the country for a SBC vs. LSx challenge.

OP, get the race on video and post it

Lol, from jersey perhaps?

First get called out of dem dare diapers little boy...

Question, why are there so many unsolved murders in Texas lmao...?

ZONES89RS

iTrader: (2)

Population if that is a legitimate question.

vwdave

High crime rate among the mexico/texas border with alot of organised crime involvement? Drug and human smuggling, etc etc etc.

Wasn't legitimate, it was a joke, and I'll just leave the answer ambiguous because Jersey folk get it...

The real answer I figure was because street lethal comes down, commits homicide and runs back to jersey.

Got anything that is actually running at the moment?

Yea, 89 camaro 6.0 still runs and drives fine. Just has a busted fender and the door dent.

STOCK LS1s should trap that. With boltons, 110mph - 114mph is easy. My X-pipe only FRC went 12.9 at 110mph in the July heat. Come Oct/Nov, I'm sure 111/112 mph is possible. Full boltons and a tune? Probably 115+

LS1 Bolt-on F-bodies

The vettes are significantly LIGHTER.

By bolt-ons I'm referring to:

• CAI or Lid
• Throttlebody
• LS6 intake
• Headers
• Exhaust
• Tune

Not saying you won't find a LS1 F-body with bolt-ons trapping over 109mph, they are out there, they are the lighter cars or the factory freaks. But 109mph trap speeds are pretty much expected when talking about the average Bolt-on LS1 4th gen.

tpivette89

Again, I'm gonna have to disagree. Maybe the auto cars do 109mph with boltons only, but its very easy for a bolton 6speed fbody to eclipse 110+mph.

My brothers 99' Z28 (fully loaded with all power options, Ttops, etc) went 12.9 at 109 with only a lid and a catback.

A friends 01' WS6 (another fully optioned car) went 13.1 at 109 with only a SLP loudmouth.

Imagine what either car would've done with headers, gears, intake mods (LS6 for the 99', bigger TBs and some sort of CAI scoop for both), tires, shifter, and tunes? 113/114mph I'd guess.

I'm just not seeing the subpar results you speak of out of the cars I've had personal experience with.

Thirdgen89GTA

iTrader: (5)

It's not subpar, it's averages. The average bolt on ls1 doesn't really trap 110+. That's not to say they don't exist, but most of them won't. You are saying every bolt-on ls1 does and that is not the case. A search of YouTube will more that don't, and a few that do.

tpivette89

Yes, EVERY bolton LS1 can hit the mph figures I claimed. However, it takes a driver who's familiar with the particular vehicle. You're not going to get good times by just heading down the the track once or twice with the car.

Also, you never claimed "averages" in your original post (even though I still think bolton 6speed LS1 fbodies should average a bit better than 106 - 109). You made it seem that a full bolton fbody was only capable of 109mph traps, and that just isn't true. I believe a vehicle should be measured on its best performance figures, not from a few inexperienced driver's youtube videos. I suppose our views differ in that respect, however.

ZONES89RS

iTrader: (2)

Hell, my carbed L98 350 trapped 101 mph with a 5 speed and only a 1.87 60 foot.

ls1 should eventually pull away.
