LS1KLR350

Hi, I've got a 1986 Camaro Z28, my mods are:

Flat top pistons. Comp XE274 Cam. Summit shorty headers, 1.6 Roller rockers, Summit vortec heads port and polish and machine work and comp springs good to .550 lift. Port matched intake. Pushrods springs lifters and timing chain are all comp cams. 50,000 volt coil. About 9.5:1 compression. And a Demon 750 carb. 2.73 gears w/o posi, stock 225 tires, stock stall, 700r4 but I will be manually shifting it for the race so I have more control over when it shifts.

The opponent.. 2002 Camaro Z28, automatic 4 spd, 2.73 gears, pacesetter headers and magnaflow catback.

We're going to be racing from a 65 MPH roll but I hear LS1's are beasts from a roll especially at 65? A bunch of my friends talked a lot of crap to the kid too so I really don't want to lose, I go to school with him and I know I'll never hear the end of it if I lose. Please tell me I'll destroy him..

Do you have good heads on that motor? Doubtful w/o them, all that cam has to breathe. How on earth does that thing idle on a stock convertor w/that cam? I run something similar and have a 3200 stall and could use something higher. Going from a roll you'll do better than from a dig w/those gears though. Run him and see what happens, you never know??????

With that screen name you chose... I would hope you could beat one?

He is going to win. The only thing better about your set-up is the cam, which in itself will likely not be enough to best him. His car should be making 320 to 340 rwhp.

I've raced a few ls1's and they get down even stock....since u have cam and heads it should help leveling the playing field more but exhuast on those things really help. And they will pull hard from a roll. I agree your best chance is to say that rolls are for ricers and try to get him from a dig. Hopefully he doesn't launch good and u make him look like a joke. Then retire as champion.

studdmstr

I think you're going to have a problem from a roll or a dig unless the guy can't drive. I would definitely stay away from racing from a dig with those gears and those skinny stock tires.

-edit: I miss read what gears you had and thought it said 3.73's. You'll do better from a roll with those but I wouldn't run from 65 mph. I would try to get something like 35mph. Like Street Lethal said you 700-R4 won't shift into fourth at WOT so I think you are going to run out of RPM's starting at 65mph. Either way I think you're going to lose.

10secondhopeful

You should have him. Your gears suck, 3.73's, a torque converter, posi, and better tires and you would run mid-high 12's with the vortec set up. there is a vortec post in the tech and general engine forum with peoples vortec set ups that will give you a better idea. It'll be a close race but i'll think you come out on top. why race from 65 only?

Street Lethal

3.73's will only hurt him if he's planning on racing from 65-mph up, especially with a 700-R4. Remember that at WOT, the tranny won't shift into fourth, so that LS1 will eat him alive w/3.73's. From a dig he might have a chance w/better gears though....

Sorry to say, probably the LS1 especially at that high of speed.

tpivette89

if alls you basically have is the cam and some stockish vortecs youre gonna get destroyed

2.73 + no posi?
skinny a$$ tires?
stock stall and trans?
shorty headers?

those = LS1 killing you

you also didnt say what engine you have... id assume it was a 350, but you said nothing more than "86' Camaro Z28" and those came with 305s. also, which intake manifold?

from the limited info you provided there doesnt look like theres any hope for you

1brd2brd3brd4

65 roll? Where you going to race, Bonniville salt flats? with those gears you should beat him there. Let me sell you a possi and some gears so you can go from a dig. At a roll start going that fast just dosent make much sence,your already half way to topping out. a 15 or 20 roll makes more sence. And yes I know LS1 and 3rd gen cars will go faster than 130 but how often do you have enough highway to do it. I know there are places that do but not around here. I have an LS1 car I have not done anything to it. When I got it, it had a flowmaster muffler,and a K&N air filter. I did add an SLP high flow air lid however. The car runs 8.58's (1/8 mile) on street tires. I ran a buddy of mine on the street and his car dyno'd 348 hp to the rear wheels. It came down to who got the jump first basicaly. So I wouldnt throw any money down.......

Sorry I forgot to mention I've got a 350 but its a crate motor the car originally had a 305.

We're racing on the freeway at like 9pm its 3 lanes and nobodys ever on it.

So it sounds like I'm going to lose oh well lol, thanks for the info guys we're racing tommarow.

Your only chance to win is if you race from 130 MPH roll.

PHAT89TA

u will most likely loose. ls1 are top end cars. might as well reconsider changing ur sn.

Toyota h8r

ls1 hands down is going to win

i had a 95 lt1/m6 trans am with 3.42 gears and a bone stock ls1 auto camaro keeps up with my car until around 110....which is where i let off ... I ran best a 13.6 with just a CAI

im doubtful the thirdgen in this race has a chance

Nub383

Don't race this guy unless you want to get beaten. I just got rid of an Ls car (99 ws6) and they are made with one goal 155mph or end of road whichever comes first. Mine when it was stock was lethal. Break your leg to get out of it and while you have your cast on, maybe he will forget about the race. Either way, good luck.

So I take it this race never happened? JFWIW - my 2000 came with 2.73's... it went 13.46 @ 104 bone stock - 26K original miles. 65 MPH will put him in 2nd gear, he's going to pull nasty on you from that speed. My car w/ just a lid & a cut out went 13.20's @ 106 MPH. Either way... get it on video.

89IrocZ350TPI

The LS1 will probably win. Just DO NOT race from a roll. Your only chance is a dig, and a short one at that.

yup, ur gonna lose, unless you put a ls1 in your car

studdmstr

I guess the race never happened.........or never was going to.

89IrocZ350TPI

Well I think we talked him out of it. Just a little bit lol

rideon1200

[I] have had several third and now have a 2002. You have no chance. ZDollar for dollar you can make more HP with a LS1. They were the fastest production firebirds/camaros made, a little known fact. The speed limiter is set at 165 and they will bury that. In fact the new 2010 Camaros will bow down to them.

joeblow

race him for pinks.......I bet you'll win.

TTA 1387

Actually, the "fastest" was a 89 TTA. It didn't have a limiter and could go 170+. That is a even lesser known fact

But in this case, it wouldn't matter as the LS1 will win.

89IrocZ350TPI

LS1 cars can hit high 12's stock. I dont think the TTA would do much better than a 13.4. It was rated around 250rwh, and 300 flywheel I believe. Compare that to an LS1 that puts down roughly 325 at the wheels, and 350 at the crank. I think the LS1 wins.

89IrocZ350TPI

The Z28 is said to put out 576 horses. IF it gets produced seeing how GM is in deep. An LS1 vs a new SS might be close. However the SS will be making 426 horses...

its funny how people think the LS1 is an unbeatable god of all engines. ""i heard a stock LS1 can jump a beer can STOCK!"

they are superb engine design, when u got nissans, fords, aftermarket tuners making ls swap specific for there cars. even the fox body and sn95 have part no. tubular kmembers for use with ls swap.
went to fun ford weekend with a bunch of ls parts and i sold out quik

iTrader: (2)

the ls1 is a great motor. but like all other cars. its has to be driven. my friend josh had a 98 trans am auto best of a 13.5 @102. my dad just got a 98 trans am auto with headers, 4.10 gears and not sure what else. did a 15.4 @100. well car spins really bad and my dads first time at the track in 25 years. point is!!! takes more than the motor to make the car fast...... tires and driver.

89IrocZ350TPI

I think its mainly the people on these forums since our thirdgens were pretty underpowered compared to the newer designs.

J91

There's no doubt it's a good engine, but I agree w/ the statement above, a well built sbc can run w/them and beat them. Yesterday I handed a 06 GTO his ***, light to light and on the freeway. I have to agree that 3rd gens are underpowered, which is why so many people are in awe of these motors. Someday I'd love to have an LS motor, but in the meantime, my 383 will do just fine...

TTA 1387

HP numbers don't always tell the story. A stock TTA will out torque a stock LS1. Weight, gearing, and driving also come into play.

Maybe so. The LS1 is definitely a better engine than the old small block and the Buick V6. I really like how easy it is to mod and make fast. Still doesn't come close to making a TTA fast for the money. Both will run equally as well, one just takes more money to get there.

Street Lethal

iTrader: (16)

There have been many documented Grand National's and TTA's that dipped well into the 11's, bone stock, they just upped the psi. Don't underestimate them....

Street Lethal

iTrader: (16)

I gotta disagree. You know as well as I do that the ports as well as the valves in the 3.8 cylinder heads are tiny, and yet, they're still running the numbers. Open them up and it's an entirely different ball game. LC2 > LS1 any day of the week....

89IrocZ350TPI

Then put a turbo on an ls1 and see whats up. that would be sickk

Street Lethal

iTrader: (16)

Well that's the thing though, the LC2 came with a turbo, the LS1 did not. So in essence, the LC2 is a much better factory engine, with or w/out additional mods, than the LS1 is. Yes, you can add a turbo to an LS1. You can add a turbo to any engine, for that matter....

89IrocZ350TPI

In the end its really a drivers race. Overall I think the LS1 is a much better design, and it should be since it is over ten years newer. Doesnt take much to get them to 400 hp.

TTA 1387

The LS1 is a better engine. Better block, better heads, just better. Force air through a head and it'll flow. The TTA heads flow better than the GN heads.

That's not to say that a LC2 running 9's is no slouch though. I really like that little engine. Wish they could have kept developing it.

If I had it to do all over again, I'd get a LC2 over an LS1 anyday. Too easy to make them run
