i am aware that the ls1 has more hp but in terms of the complete package which would you guys say is better? i raced a silver ls1 trans am and was in my 97 black ss lt1 he took me but not by that much. with a few cheap mods like cutouts an intake and another 15hp id say an lt1 could run with an ls1. i personally think the lt1 sounds much nicer than the ls1. what are the actuall power ratings. i know both the ls1 and lt1 were underrated. ls1= 350 hp 365 trq lt1= 300 hp 340 trq. actual numbers? the hp varies year to year as well. in 96 they got another 10 i believe or something

 

was this with your stumbling problem at mid range rpm's ?

 

i agree that an lt1 sounds better...but taht's all a matter of opinion. as far as which is better? well obviously i stuck with the lt1, however i'd have to say the ls1 is a better choice. its got a very solid platform to work off of and its newer technology

 

^^^ x2

 

Their both really old technology, antics as you might say. Hell even the LS3 in the new camaro is outdated. Untill they bring back the double over head cam set-up that was in the LT5 and is in my four-runner, all I have to say is grow up!

 

The LS series is manufactured from recycled aluminum cans!

 

this is the crap i'm talking about...

OP, don't listen to a word craZ28 has to say

 

i thought the main diffrence between them was the heads and cam?we all know the intakes diffrent aswell but thats not a big deal along with other odds and ends.But there both 5.7s i say you could swap heads and throw you a cam in it of your choice and stay with a ls1 if not walk it a lil.

 

The LT1 is an actual 350, the LS1 has a whooping 4 more cubic inches in it..
The LS1 is newer, and has more HP but personally I'd rather have the LT1.

 

wow...lots of uninformed in here

the LS1 is a 346 while the LT1 is a 350

parts from an LS1 are not interchangeable with an LT1
