Are you just asking about the stock bottom end N/A ls1 in a fourth gen camaro/firebird behind a 6 speed?

Yes sir. Like i said I'm no where near it but I was just curious.

Fastest N/A on the list is ls1joe at 8.69. He was running a 403ci setup though. I believe he went as quick as 10.10 with the stock bottom end ls1. RobZ I believe went 9.98 with a stock bottom end in a corvette. WS6 TransAm01 has been 10.32 on the stock bottom end and I believe he has gone a smidge quicker with some difficulties. Smokin01TA went 10.21 on stock bottom end and stock heads.

https://ls1tech.com/forums/drag-raci...ing-again.html - ws6transam01 thread on his new best


https://ls1tech.com/forums/drag-racing-results/1646702-shake-down-w-new-h-c-i-setup-10-9s-128-a.html demonicbird00 has a good setup just need some bias ply tires and I'm not sure if he went to a 4.30 or 4.56 gear.

Also 98bluesscamaro has a thread going where I believe he is pretty determined to run 9s on the stock bottom end 346 behind a 6 speed. I'd follow his thread.
https://ls1tech.com/forums/drag-racing-tech/1668803-98bluesscamaro-sbe-heart-trans-plant.html I think he has been 10.50s at 130+ but it was not an all out setup. His new setup will be impressive I'm sure.

Studderin has loads of good info for 6 speed cars. Here is his cam only thread, best of 10.65 I think on a 275 radial. Not sure if he ever ran a H/C setup on the stock bottom end. https://ls1tech.com/forums/drag-raci...itch-diet.html

Lots of good info to learn from all of these guys not just the fastest person but stock bottom end 346 behind a six speed is 10.10, I think, could be wrong. Anyways check out these threads from these gentlemen. Hope this helps!

Gotta start somewhere! These guys were 12 and 11 second cars at one point I'm sure. Just spend some time, money, and optimize your setup is a huge thing.

Yes, I believe 6SpeedInc (ls1joe) still has the record for fastest NA 6spd. They even put 5th and 6th back into the trans just to shut the people up who were complaining about it not being a true 6spd.

10.10 was their fastest stock bottom end time.

Rob Zona's T56 was converted to a 4spd, no OD, but its still a T56.

I am not even close. 10.24 was all I did last fall, could not hook worth ****. Trying to work it out this fall. It will never be a 9.69 setup, stock CID is all I gotz.

What compression are most of these motors? I just want to hit a 10.9x with the 3:73s in and then spray it with a 200 shot. I havent had any clean runs this year on slicks so who knows if that will ever happen.

Does a slipper clutch and faceplated still count as m6?

Alex I wish I lived closer I would have no problem helping you get more weight out and better 60 foot times.


And yes my build is still under way it's changed a lot along the way but should perform well.

My compression is 12.3.1 with stock rod bolts that never been messed with and spun as high as 7400 every pass. All I can say is a good tune and fuel is key. I use e85 and it really helps the bearing life and rods and rod bolts. Because I don't get the knock you do with 91or 93 pump gas and e85 loves compression.

In my opinion, yes.

We have a decent shot at running 9's with a stock ls6 plus all the bolt ons with a stock t56 and stock clutch. I'll keep you posted.

FinalCam

iTrader: (2)

After you all get all you can with bolt ons are you going to run it cam only or a H/C setup on the stock bottom end? I have visited your thread a few times, definitely impressive! Best of luck!

Yes it still counts. I run the fastest M6 thread and I won't cut the list because of a slipper clutch, a faceplated gearset or even removal of 5th and 6th gears. No matter what it is still a T56 with the power going through the same input and cluster gear in the same case. And the transmissions are still manually shifted with a standard shifter.

Mullettt

I still count it as an m6.

As far as motor and e85, I will most likely take my heads and cam out and get a better combination with higher compression. As far as the e85, if you dont mind me asking what pump and injectors are you using? i have the racetronixs pump and relay now with cobra injectors so i know i will def need to upgrade both. and at the same time i will be throwing a aftermarket intake on. Fast, vic jr, im sort of stuck on intakes at the moment.

street driving Or track only also I have a fast 102 for sale . and for E85 you need big big big injectors. I run 80 lbs injectors. also I run twin intake fuel pump's.

Thanks.
We have a race motor sitting around that makes ~950fwhp that we can drop right in, so If I do anything other than stock I'll go that route.

I'm still having fun with the stock ls6 though and it requires almost no maintenance.

Sorry to the OP for the hijack.

Peolpe should understand that:
Types of adjustable clutches vary more than standard clutches. I've owned many of each.
Some adjustable clutches are 100% streetable where others are race track only.
Apples to orange.
Alot depends on the setup and power level. Adding certain raceparks to a stock powered vehicle can sometimes make it go slower.
A manual 6" prostock quad disk clutch can't even be compared to many of the adjustable cluches on the market in price, quality, streetability, et potential etc..

I believe 7's are possible n/a with a liberty trans, prostock clutch, 9" rear.
A setup like that is worlds apart from a t56, c5 rear, IRS suspension, aftermarket clutch.

And don't believe everything you read,lol.
There's a ton false info out there and even in this thread.
Goodluck and enjoy.

I know at this point I may as well get the cut-off wheel and go to town, but I just can't bring myself to do it lol.

Last time on the scales it was just a hair over 3300lbs because I added a drag bar which was heavier than my 25mm sway bar and a heavier torque arm. Not sure if the SFI bell housing weighs more than the factory alum. one. The car is actually a few pounds fatter than it was with the older setup... D'OH!
