Last thread I posted was LS1 vs LT1. I wasnt asking about what would be a better swap. I like the 3rd gen body style but apparently the LS1 is a more superior engine. So would it be better to just buy a 4th gen for the more superior engine or just get a 3rd gen. 4th gen body style is still sweet but if theres not a huge differnce in power than I would rather just get a 3rd gen. so heres the question is it worth getting a 3rd gen for the body and sacrifice the power that come in a LS1?

 

test drive,

the Ls1 is better but the Lt1 i a great engine too. There both the same size but the Ls1 has better technology so it more effiecient and about 30 horses stronger. I would base my decision on the body style because the engines are pretty much the same. Ls1=320 hp, Lt1=290 hp. its a smal difference that you really can't even feel.

 

OK, first off, are you talking about the LT1 body vs the LS1? because they are BOTH 4th generation F bodies.

3rd gens are the IROC style bodies.

If you are talking about the LT1 Vs LS1 the LS1 is a good bit faster, though most people say they actualy feel slower. either is a good choice. but stock the LS1 wont think twice about showing the LT1 whos boss.

If you are talking about the true 3rd gens, the LS1 is in a whole other class of motor than what they came with.

A race of a stock 3rg gen and a stock LS1 is pretty much a guaranteed butt raping of the 3rd gen. (there are a few rare third gens liek the TTA that would be a good match) unless the LS1 guy has his thumb in his butt when the light turns green, and leaves it there for a few seconds...

 

No doubt that a 4th gen LS1 will burry a 3rd, stock for stock that is. Also there is no doubt that the LS1 out perfroms the LT1. However, the extra power comes with a price look that some of the problems the LS1 people have had at the mileage they've had and compare it to the problems people had with the LT1 under the same harsh driving. The LT1 has far fewer problems as a whole. If you really want power look for a Comp T/A that came with the LT4 in it. When you up the stakes on the power you up stakes on reliabiltiy. Look at GM's 302 ci concept car that made 435 hp. They didnt offer it because they dont want to replace head gaskets twice a week. For performance and reliability the LT1 has to win. If you have your choice between 3rd and 4th gen get the car with the body style you like most. Its all a matter of Prefrence and opinion. PLEASE NO REPLIES ABOUT LS1s BEING SUPERIOR or LT1s being inferrior. This is just my opinion.

 

with a lt1 and ls1 your still in the same ballpark.....

with a third gen you are over in another country lets say IRAQ




ls1 will beat lt1...... lt1 will beat third gen

ls1 will smoke third gen..... and make it look like iraq after we get done with it

 

I love 3rd Gens...I had a 1989 Formula WS6. Having said that, the LS1 F-body is leaps and bounds the all-around better performer. The 3rd Gens have a weight advantage, but not all that much and the aluminum-block LS1 provides better front to rear balance. The LS1 has better brakes and ABS. The LS1 has an availible six-speed manual, but I don't know how much better the 460LE is than the 700R4 I had. Power-wise there is no comparison except in low-end torque. The L98 is a monster down low, but runs out of breath fast.

 

I belive the 4L60E is a 700R4, they just redesignated it when they went from a hydraulic to a computer controlled valvebody.

 

I remember the first gear in the 700R4 was excellect and that tranny took some abuse!

 

Actually both trannys are equel for gearing except the 4L60E is actually built stronger compared to a Stock 4L60 (700r4). Don't take that as much stronger but they can handle more abuse then the 700 could in stock form.. When comparing the clutchpack sizes of both 700r4 and the 4L60E, 4L60E has more clutches in the clutchpacks compared the 4L60 (700r4), so they are a little stronger but both trannys can be made to be as strong as a TH350...

 

Thanks for the info! I haven't had the opportunity to drive a 4th Gen with an auto. Most people swear by the 4L60E, so I imagine it is pretty stout.

 

Wow....I've never seen this asked before. The LS1 would smash a third gen. But that does't make them bad. I stiil have a soft spot for the 1990 RS I had with 150,000 miles in excellent mechanical condition. If I found a 3rd gen with a TPI for a good price, I'd nab it in a heartbeat. (No pun intended.) A TPI 305 made around 300 lb-ft of torque. The 350 TPI pushed 345 lb-ft. Impressive for those days. Fit a 350 TPI in good shape with a set of Vortec heads and the Vortec/TPI adapter manifold that makes all the pieces fit together, you've got near 300 hp. Ask this question on the third gen forum. See what they say. You can get a 3rd gen, and work on it. You could get an LS1 and go mid 13's the same day. I personally was sold on the LS1 the second I drove it. My mind was made up. I would just like a 90-92 Z28 to play with, but I would always want the LS1 to rely on.

 

3rd gen + zz4 crate engine, and you have yourself a pretty stout ride. Plus the 3rd gen is a lot lighter than the 4th, so you wouldn't need as much power to make it go as fast. But is stock form, yes, the 4th will whup up on a 3rd gen.

 

Ram Jet 350 crate engine = LS1 Power in a 3rd Gen

 

Or ya could just do this : http://www.thirdgenresource.com/91_z28_ls1_convertible

 

Hands down LS1 will out power a L98 3rdgen stock for stock with NO arguement from me but for bare minimum for mods and at a piggish 3688 lbs w/ driver Ive taken my dead stock L98 engine as far as 13.521. I dont put up any kind of MPH but the car shines thru the 1/8th and I usually get .4-.6 on your average driver right at the 60ft if Im DRs. Sad part is they usually come back to get me at the end Want to see what I mean?

13.9 run .
This was on street tires and directly after arriving at Atco NJ. Next run was a 13.758 at nearly 100 MPH which is my best street tire ET to date. I know even if I have untouched heads, intake, gears, rockers, cam, manifolds and only bolt ons its still comparing modded to stock but 90-92 L98 dual cat SD cars are no slouches and routinely see 13s with minimal work which puts them not as far off the mark as many would like to believe. Still doesnt mean Im not searching at the moment for a low mile super clean 6spd 4thgen for my next car, hopefully a Vert

13.9 at Etown. Another LS1 car another 13.9 and another poor MPH on my part. Sad part is I run 13.50s at the same MPH but I also have issues with the car that I havent worked out yet and probably never will since I may be selling it soon.
