If you want to run with an LS, you'd probably be best off going carbureted. LS1's are very potent and with just a few mods can get fast, they flow a TON of air which is why they run so strong.

MrDude_1

uhh.

take off the bold.

take off the caps.

use some punctuation, and split it into something that somewhat resembles english.

if you want someone to reply, try throwing a question in there.

MrDude_1

the only thing im trying to do is:

1. make your post readable, so that its not only helpful to you, but to others.

2. tell you to put a question in there, so that theres something to answer.



can i help? hell ya.
am i going to attempt to read something in bold, all caps, with no punctuation? no. and dont expect others to either. just be thankful that someone took the time to tell you WHY no one wants to answer your thread, instead of just thinking "what a moron" and clicking on like everyone else did... look at the views, then look at the posts... you'll see what i mean.

the stock 48mm throttle body will flow enough air to support 600hp, spend your money somewhere else.

Now that someone interpeted the original post (thanks Matt), What you are getting into is comparing a car with maybe 220 to 225 Hp to a car with 290 (Z28) or 305 (SS). You must add about 50% to your engine Hp, a very tall order, and then you might get a fender on the LS1. You will have to do most of my mods; alum heads, full exhaust, gears, cam, full intake, and get a good tune.
I have a great idea, just by an LS1 for yourself and save yourself alot of grief.

The ls1 will still beat you. with a t56 they only lose somthing like 15% loss through the drivetrain. your automatic l98 loses allot more that that. you need like a 350 or 383 with an lt1 intake, cam, aftermarket heads ect the ls1 is a beast of an engine and will laugh at a mild l98.

Ummm no.... actually there is no horsepower difference at all between an SS and a Z28 with an LS1! And Your horsepower estimates are quite off too. Most stock LS1's make somewhere between 285-315 to the wheels alone! Some slightly higher or lower. This equates to roughly 330-375 at the engine.

shaggy56

I was blown away when I heard one without the silencer. You can feel the power in your bones. I need one now.

MrDude_1

you're confusing "factory ratings" with actual HP.... the LS1 actually puts down over 300 at the rear wheels.... regardless of the "official ratings"..

MattODoom

iTrader: (1)

The LS1 is a hoss, but it's not god.

MrDude_1

LOL. so what are you trying to tell me? that all of the stock LS1s ive seen on dynos are wrong?


lol, most put down between 305 and 316... occasionally the factory freak thats alot lower or higher, but thats the general range.

hell mine, thru a stock 99z catback, put down 316 uncorrected on a humid, hot day... corrected its 326 or so...

MattODoom

iTrader: (1)

It was not in regard to your HP figure, i meant in general, people just think the LS1 is the greatest thing ever. I drive an 88GTA and a 98 SS, I can tell you that yeah its great out of the box, buts its not unbeatable.

And when people post up how they can build their gen I and people just say "aww **** it get an LS1.." really not helping much.

MrDude_1

well,
i suppose i could reccomend a diffrent bottom end... because you need atleast a 4" bore in a SBC..

then i could reccomend some good aftermarket heads... none of that 23* crap either. we're looking for something competitive here.

then of course, you need a new intake to match the heads... either converted to EFI, or go carb.

and a upgraded ignition system.

and then you need to upgrade the clutch, and the t5 needs to be replaced...



or you can drop in a stock LS1 drivetrain, toss a cam in it, and make the same power..... either way, its the same power.

shaggy56

Well then do every mod everyone has ever done here then you will be there. Then go to the dealership and get a 2002 LS1 of your choice and then you will have the best of both worlds.

MattODoom

iTrader: (1)

Yeah cause the LS1 just falls right in the car. Its not a bit of wiring modification to make things work and theres not $700 headers you have to buy if you dont want to run manifolds. Oh yeah and the motor is cheap to begin with too right? How about swapping to a LS1 gas tank as well? The **** adds up.

Personally I am building a stealthrammed 406 for the GTA. It has worked over vortec heads (huh... arent those 23*?!?!) and will be backed by a T56. Id like to see the cammed LS1 make that same power.


aww **** it I dont even want to argue with you guys. We have both a Gen I car and a Gen III car and they both run great.

take a look at your goals, your mechanical and electrical ability and decide which is the best route for you.

Not everyone can take on the LS1 swap Mr_Dude.

MrDude_1

actually, the LS1 does just fall in. atleast mine did... it was actually easier then the old SBC.
i made more power with manifolds then 95% of the people here make with their SBCs.... if that comes off as cocky, so be it, but its correct.
the motor, trans, PCM, clutch, ect... pullout costs less the just the cost of the SBC engine built to match it... so its like a free trans, clutch, and EFI system.
the wiring is simple.
im using my stock 91 camaro tank. id reccomend keeping the 3rdgen tank... and keeping the 3rdgen radiator too... and keeping the stock fans.. hell, keep as much stock as you can... cheaper and reliable that way.

im sorry to disappoint you, but i HIGHLY doubt a stealthram 406 with just vortec heads will make the same power as a cammed LS1... and if its too close for comfort, the LS1 owner could just bolt on some ported heads... for $600 new.... try finding heads that flow like them that cheap for the SBC... (hint, you can port vortecs all you want and not be close in price or flow.)

btw, that T56 swap costs between a quarter to half the cost of a LS1 swap....

MattODoom

iTrader: (1)

lol. Come on man... GM sells crate motors with mild cams and TPI vette heads that make the same horse as LS1's. And those are 350's.

That's great, but they have easily 4x as much money in just buying their car then I have in mine. So whats the leave me with, $12,000 to put in a motor just to get to where they started?

And it will be well worth it! T56 >>>>> 700R4

PS: Im not trying to start anything with you, just defending the good old Gen I's.

MrDude_1

and have you PRICED thoes?! for the same price, you can get a low mile pullout LS1 with cash to spare.


when i said LS1, i ment LS1... LS1 is a engine RPO code.. im talking about the engine.. or the engine/trans pullout....
in no way shape or form would i endorse buying a LS1 fbody for 12,000.... esp when you can get a reasonable mileage one for 7k or less.




just a reminder, half of a LS1 drivetrain pullout...... is the T56. lol.

im not trying to start **** either... but its just amazing how people defend one motor, without knowing anything about the other..... the other motor is absolutely amazing.. in both performance and price. people just assume the SBC is cheaper, without ever looking at the cost of the LS1 parts. the only way the SBC is cheaper, is if you settle for less performance then the LS1 is stock.
but, when i mention that on here, it usually falls on def ears... i know, you guys would rather replace every part on your motor to start making decent power.... and then defend how great it is. and thats fine.. i mean, people have been doing that to thirdgens since 1981. (82 model year went on sale in 81)

MattODoom

iTrader: (1)

Well actually LS1 parts are quite expensive. Intakes are what $700? Headers are $700.

The differense is really that you have so much more to start with and get so much more from mods that dollar for dollar the mods are better.

Personally I think the gen I is great. I grew up working on them, theyre simple and a great way for gear heads to get going. Theyre easy to tinker on and work on and just overall great.

Perhaps you would like to consider the SBC Gen I the intro motor for getting into cars and horsepower, and the Gen III the graduated level powerplant :P

big_nick_kgm, please turn your caps off. are you from the USA?

a L98 comes stock with flat tops with valve reliefs, the compression is around 9.3 or so.
any major mods you make pretty much need some chip work.

urbanhunter44, i know, his posts started out pretty much ok at first,.. but went down hill the longer he was here,.. i think he maybe spent too many nights with mary jane & her friends, if you know what i mean

ThirdGenLS1

Just some food for thought, im making almost 500 at the crank with my ls1(430 to the tire) and still running my crappy y-pipe set up, and havn't even touched the throttle body or intake.

But i'm not saying they are the end all of all motors. The nice thing about though is you can make big power and still be 100% drivable, my drives almost like stock.

But on another note, they are kinda pricey (not as bad as you guys make it sound) and building a old fanished SBC will generate a lot of power if you do it right.

Like i always say its your car, your money, do with you want, as long as your happy with it thats all that matters.

As far as what heads, cam, etc are "best" - I would recommend doing a search.
Over the last several years, I have had many questions about improving my car's performance. Searching this vast website has helped me learn alot about my stock parts as well as aftermarket performance parts.

As far as building a motor just to beat a 2002 Camaro LS1 - why? There are other motors out there that are faster. Will you keep rebuilding your motor to beat them all? It has been my experience, over the years, that you need to build your car faster/better for yourself... for the joy of being a car nut. Not to race people on the streets. That is a great way to end up in the hospital or worse! So get what you want out of your motor, but don't get carried away in "my car is faster than yours" insanity.

Sorry for the zen speech. It's only my 2 cents.

Hope this helps.

Best of luck!

He's been back for some time now.

I have outrun ls1 cars repeatedly including a coupld of ss camaros. the only one i lost to was a highly modified TA. it had cam, heads, headers, exhaust, NO2 and who knows what else. that car was freakin fast but what fun it was running it. after i pulled his stock 04 cobra he went home and went on the hunt for me with the TA. that should tell you something about that car.

now, having said that and still doing modifactions to my car. if i had to do it over again............i'd buy an ls1 off ebay (or elsewhere) rather than spending quite a lot of money and time on what i have. the ls1 is a proven engine.

why spend the time and money playing mad scientist when you can buy frankenstein from the get go? just my

LS1's are neat but they're still not in my price range. If they were, I woulda got a C5.. Sure once and a while I see a "deal" on a stock LS1 + T56 combo, and I'd think to myself "Whats another 6k gonna hurt". but then I look online at all the LS1 parts. heads, intakes, cam, headers, engine swap motor mounts, and all that.. nah.

If LS1's and LS1 parts were as cheap as SBC parts, i'd prolly jump at it. But even silly things like ECM's and sensors are still crazy big money.. dollar for hp it just doesn't make sense. Not to say your LS1 swap isn't cool stuff. We're glad your happy with it. Well at least I am, I can't vouch for some of the other idiots on here
