This is just a question I have for everyone. Which setup is better Overall? In all aspects. I just want to seek different people's opinions instead of all my friends. I'm also trying to decide which of the 2 setups I want to build!!!

 

you guys can have fun with this since i know this topic never comes up

 

I wouldn't touch this one with a ten foot pole, and I've got my flame suit on.

 

Its not a big deal to touch this subject.

I own a 94 LT1 383, thats decently built, its decently fast. I enjoy it. My best bud has owned a 94 T/A GT, 93 T/A, and most recently a 2002 Z28 6speed.

He crashed the 94 a while back, got the 93, its the bastard year LT1 with a ton of miles and just fustrating. He got the 02 with 4,500 miles and every option except traction control. It has some mods done, all bolt on and traps 110mph..... freakin insane.

So as I try to explain I have seen personally both sides of the issue.

LS1 is a better motor, bar none.

The reason I say that is frankly GM (and other parties involved) developed a motor from the ground up, it is a totally different design from the GEN I and II Small block chevy's. LT1's are GEN I Small block chevy ver. 2.0

Alot of the old technology coupled with some new goodies made this motor. BUT being Iron block vs. Aluminum is a HUGE weight advantage, not only in over all curb weight, but weight transfer. The Cylinder heads flow something rediculous. A good set of AFR's go over 300 cfm from .500-.650" lift with out issues.

But some people get cocky, mainly LS1 owners and think their motor is made from the hand of GOD, and everything defies general, common logic of basic engine building and performance. So dont think your car can beat everything, there is always someone out there, faster......


So long story short, MOD FOR MOD, if both cars are set up the same, as best as you can do it. Do one mod, for one mod. LS1 should be faster everytime.

 

opti sparks are the devil too (take 1 point away from LT1s)

but.....LT1s sound cooler

 

search.

 

the LS1's have more options for engine sizes..... Like a 427 Stroker. i wish my LT1 could be a 427 stroker and still keep reverse cooling heads

 

I forget where I was reading on here (i'll have to search it) but it was possible to do a LT1 427 stroker motor. I don't remember if it still had reverse cooled heads though.

As for on topic, I'm with Vendetta & jrp. Try a search. This will eventually turn into a 9385732987 page argument.

 

there is the exact same thread still on page 1 in this forum. people need to search BEFORE posting.

and the LT1 ownZ the LS1 anyday.

 

please find that info for me im very interested.

 

You'll need a lot more than a flame suit. More like a titanium reinforced concrete fall out shelter. Then you'd still need the suit. I regret posting the threads I did because I damn near started WWIII, lol.

 

Both great motors !!! IMHO. OK ls1 in stock form has better heads, cam, intake & ignition system. So on the lt1 all of these can be fixed now and even up the score. If you are staying close to stock form get the ls1, better car at that level. If your going to mod the hell out if then either way you would be fine.

 

whaaaaaaat o is on now sucka lol




this will be fun to watch.

 

I know for sure is over on Camaross.com. I'll look a little more but didn't stuble acorss it. A search here or on google will get you a lot of good information if you just read the posts.

This is a good thread to read... Bret (SStrokerAce) has good advice on larger cubed LT1s.

Hope it helps. If I run across that thread again, I'll be sure to PM you the link.

 

Both are definitely great motors with a lot of potential, it just depends on what kind of a budget you have. If you have a limited budget the lt1 is a better choice, both the car and the parts are much cheaper. If you have a bigger budget the ls1 is the better choice, it doesnt take much modding to get decent #'s out of an ls1.

Bottom line, they're both sbc's.

 

Put some really good heads on an LT1 and go whoop some LS1 ***.

 

In a semi abbreviated version...The LS1 has more potential it seems. Due to the following: 15* heads that flow stupid amounts of air, lighter, crazy aftermarket. The LT1's charm is that it is cheap to build and loves the N20. Also another little known fact is that the LT1 will accept Gen1 heads and also canted valve (sbc2.2) heads with conversion to reverse flow cooling. This is not possible on LS1's...although there are some very nice heads out there for that motor. In reality, it all depends on your goals, budget, and what's readily at your disposal. Now for my .02...

The LS1 can run extremely fast with minor mods. Example...the fastest "cam only" (all bolt ons and only internal mod is cam/valvespring/rockers upgrade and sometimes rod bolts) LS1 runs something like a 10.2.

Likewise, a LT1 with all the bolt ons and a cam might be able to muster a bottom 12, or just a tick faster. Most of the gain can be attributed to the heads, and also another point of argument is that more people with the funds and knowledge to mod a LS1 to the point of amazing times own LS1 cars and are modding them intelligently. In other words, stereotypically, your common LT1 owner is a kid in HS, with limited funds and knowledge....or an older person who wants power, but doesn't want to go ***** out. There are obviously many exceptions, I was just generalizing, sorry if anyone took offense.

If you are looking to spend the least amount of money and only want to make 350-400hp and run bottom 12's, high 11's N/A then clearly the LT1 is your choice.

If money isn't a huge worry and you would like to make the same hp, yet have room to grow if you get more serious...by all means step up to the LS1.

If you want to build a ***** out street/track monster and you can take your time piecing together the most effective setup the LT1 is arguably the best bet based purely on price and more effective head choice (SB2.2....mmmm)

No doubt the LS1 has run amazingly good times, and will only get faster and more affordable, but the way things are right now...you could build a 8-9 sec LT1 beast cheaper (relatively) than a similiar LS1 car..based on total investment.

Hope I didn't offend anyone and I prepare for the flaming *smokes last cigarette and ties blindfold....*

 

No flaming I agree with a lot of what you said, bottom line is $ invested . Both camps have sick cars!

 

Dude forget what all these guys. Screw the LT1 and LS1 and buy yourself a real L98. It loves N20, superchargers and many cams in many shapes and sizes Im ready for the flamming now, i got my kevlet fireproof astronaut suit on.

 

to tell you the truth...(click on pic).....both are great motors and they both have there own ups and downs. in the end its all gonna come down to how much money you have and if not that then its your own prefrence.....i smell fire
