why do the ls's get so much love and the lt's do not? why does the ls1 do the 1/4 a second faster than the lt when the displacement is no different (what compensates for the extra hp on the ls)? thanks for helpin a newbie out.

 

we are gonna pretend like you never said this!

 

totally different engine, new technology. the LT1 has been around since the 70's and the LS1 has good flowing stock heads and intake manifold. Hope that helps. But LT1 is stronger and is more "torquey"

 

Heads, Camshaft, Intake, and a few minor improvements elsewhere.

Nothing a few mods can't fix I'd say.

 

Most of it is in the cylinder head. Simply put... air has a much straighter shot into the combustion chamber with the LS1/LS6 head. The ports are also all the same port.... so the airflow is more uniform from port to port. The valve train assembly is also lighter (cam is gun drilled) so the engine can rev higher with less valvetrain stress. Lots of little improvements here and there but most of it is in the heads and intake.

-Mindgame

 

on a more serious note an LS1 is a 346 ci, and I am pretty sure a LT1 is 350 or 348. anyways, LT1/4/5 motors are cast iron block, 2 bolt main, and alluminum heads(ecept impalla.. Iron heads) The LS1's are all alluminum, 6-bolt main block, and their heads are more similar to a SBF than a SBC. From my knowledge, the LS1's are a way better stock for stock. But because they are so different thn any other GM motor there are not that many go-fast goodies for them.... and if they are then your gonna pay out the a-hole for them. in a couple of years that will be like LT1's are now. Yes, you are correct LT1's Bone stock times vary from 14.5-13.8's and LS1's time bone stock are usually 13.8-13.2. So if you wanna buy a car and leave it stock buy a LS1, if your looking to modify then buy yourself a LT1 and have some fun.

i wasn't degrading the lt in any way, just wondering why the ls is quicker. thanks for the info. oh yeah, but essentially with better flowing heads and a little more agressive cam the lt is equal to the ls1 in power?

 

Very well said!!!!!!!!

 

yes in theory if the LT1 had the same benefits of the LS1 then they would make vitrually the same power...actually the LT1 might have a slight edge b/c of the few extra cubes.

 

lt-5s are all aluminum.

 

I see your new, do a search on LT1 vs LS1, you'll find so many posts about this subject.


As far as LT1s not feeling the "love" its like shoes, a new pair come out and no one cares about the shoes before it. its not new any more.

 

this is just in my opinion....................it might be a bias one since i am an lt1 owner ........i think the lt1 is a much better engine........the ls1 just got better goodies.........like a coil for every cylinder, where as the lt1 only has 1 for all 8 (at least i think thats right)...........and as someone posted earlier it has better intake flow..............in my opinion (this is not proven, i just think it is possible)......if you took and lt1 and had matched heads with and ported and polished intake and intake manifold....with exhaust system (or a cut-out ).......and a cai......then the lt1 could take the ls1 or be running the exact same times as a it...........thats just my $.02

p.s. -- i have only had an lt1 for about 6 months.......so if my statement sounds very ignorant, please excuse me

like someone said earlier........................we will pretend you didnt ask that

 

Corvette LT1's are 4 bolt main!
Oh yea...I handed a 99 LS1 A4 T/A it's *** with just Intake, Headers, and exhaust!!! And only spent about $800...and bought the car for $8,000!!

 

And very Badazz

 

So are LT4's if we are gonna get really technical
