A stock or bolt on LS1 is better than a stock or bolt on LT1, once you get into aftermarket heads, the advantage is significantly reduced. Essentially the heads are the only real difference. I know they have slightly different bore and stroke, but essentially the LS1 is just a pushrod small block with a nice set of heads.

 

It'll be interesting to see what their true curb weight is when they go into production. 400hp isn't gong to cut it if I ever get so lucky to line up with one.

 

I had been feeling the itch to get an LS1 just because of the motor potential. But I already have a sound LT1 that's in excellent shape. After really considering the topic, I asked myself this:

How fast is fast enough?

For a street car, I figure mid 12s is fine. Especially since I'm leaning more towards road race/ autocross now. That whole venue doesn't require sick power. So why bother with an LS1 when an LT1 can easily put down 400 or more HP? Remember, the LT1 is still a SBC, and a SBC can run with ANYTHING.

I now have 17x9.5 wheels so the corvette brakes will fit, and the spare set of heads are on my porting bench.

 

Ran low 12's with a bolt on, hot cam, bone stock head LT1 many times, I've out run many bolt on LS1's with it, probably a few cam'd LS1's too. I like that LT1 go fast parts are much cheaper than similar LS1 parts. I know the LS1 has been the better motor for 10 years now, it doesnt bother me. Would I like an LS1/2 instead of the LT1? Of course. But at this time its just a fun car for me, to swap to an LS1/2 into the car would cost me more than the car is worth and I dont have that kind of money to play with. I'm quite content modding the ol' LT1 for now

 

That all depends on the car buddy. When i only had a cai and headers, i was beating ls1 cars with headers and a lid. There are some good *** running lt1's out there, but hardly anyone notices them. They only pay attention to the 14 stock lt1's, not the mid to high 13 stock lt1s.

 

BTW this thread was not about lt1's and ls1's, its sad thats what a few morons had to turn it into.


That said. There are bolt on only lt1's running 11's, there are N/A LT1 cars with stock heads running 10's, and N/A cars going low 9's. Its a ****ing shame so many people diss the engine and try to act like its so hard to make power with them.

 

All having an LT1 means is you have to try, think and work alittle and you can go just as fast as any other car.

See the guys who are running fast? Whats the missing link? I think its pretty obvious...

 

This is easy! If you want a cheap, modern V8, and you don't want a
Mustang... get an LT1! More expensive than a Mustang, yes, but cheaper than an LS1. There is not a better dollar to performance value out there. I got my gorgeous 96 M6 @ 83,000 miles one year ago with 373's, exhaust, CAI, short shifter, chrome SLP ZR1 wheels, and brand new OPTI, water pump, and fuel pump for only 7,000. Other than the clutch turning into butter, it's been rock solid so far. DUH the LS1's are better. That's a no brainer, but you will save a couple grand going with the LT.

 

WHere do you guys get this cheap stuff from? Building my LT1 race car cost me a S**t load... and lets not forget all the parts I broke on the way there.

 

You get to a certain point where it doesnt matter what you started with, for what I've spent on my car just this year I could make a VW beatle fast lol.

 

A header CAI LT1 isn't going to beat a well driven lid/header LS1, even if you car is good *** running. Yes, there is driver responsibility involved, so you just beat the driver, not the car.

Show me some mid 13 stock LT1s. There aren't many. Probably just as many 12 second LS1s. LS1 cars are faster, period. The aftermarket on the LS1 has also gotten substantially cheaper, and LS1 cars aren't that freakishly expensive anymore. I have seen 98s go for 6 grand. Not too bad.

Highest power H/C full bolt LT1s I have ever seen are around the 450rwhp mark. That isn't too common among LT1s. Highest power LS1s I have ever heard of are around 500rwhp. Again, that is not the norm, but a fair comparison among both. Both on stock displacement. The aftermarket can only even these engines out so much. The LS1 is a better design, period.

Give me an LS1 car, and I can get it into the 11s much cheaper than an LT1 car, all things being equal.


To the guy that suggested third gens are 500lbs lighter than a 4th gen, you information is extremely skewed. 4th gens are in the 3400lb ballpark, which by your math, would make a third gen 2900lbs. That is some fiction right there. I have also seen magazine numbers that favor the 4th gen in handling, it all depends on the setup. Pulling Gs is largely a function related to the car's tires, so I wouldn't use that as a definetly arguement for a third gen handling better than a 4th gen.

 

And yet, a LS2 GTO has absolutely no trouble running away from an LT1 fbody, stock for stock, or mod for mod.

You do know there are LS2 GTOs in the 12s, right? The norms for the cars are mid to low 13s. Weren't you bitching in a different post on this thread that no one pays attentions to the cars best times? Well, a stock mid 13 LT1 ain't gonna beat a stock high 12 GTO. The trap speeds aren't even close between the two cars either.

 

Damn, all this LT1 bashing makes me want to sell mine and buy an LS1.

 

There's not very many street cars in my area that are faster than mine, the ones that are faster are not LS1's, they are old school SBC and BBC cars. Money is what makes power, and thats what it allways comes down to. If you're just gonna do bolt ons then you're better off with an LS1, if you're gonna build a nice engine from scratch it doesnt really matter what you start with. There's a guy in my area that has run 9.xx with four cylinders in a street car.
