LS1 for speed LT1 if you prefer style imho but both are good choices....me personally id love to get a LS1 and switch out the front lol

 

lt1 stroker>ls1 stroker. For obvious reasons, so no one say anything. lol

 

how do u figure? people have stroked an lsx out to 427 and run 9s NA. Its just that people more often (however im betting that will be changing) stroke the lt1. but to be fair, the average lt1 stroker ~ HC ls1. ive seen guys with 383 mild head/cam lt1's make good numbers, but not numbers unreachable by stock cube ls1

 

To keep everything fair there's a stock block, 350 CI LT1 that's in the 10's...

Nonetheless, a stroked out LS1 is still going to be better than a stroked LT1. The LS1 is just a better engine design that allows for better numbers overall due to a better designed head that allows for better flow, larger volumes and higher lift, it's a plain and simple fact. Now, let the argument die...because there is no agrument

 

the point i was making is that if a motor performs better than another at displacement A, the figures wont swap at displacement B. they will only be >/= what they were before. and as we have said several times, its because of the head design. if the ls1 is better, at ~ 350cid, at getting air in and out of it than the lt1, why would someone say that @ 383cid, the lt1 is suddenly better? thats crazytalk, and it completely ignores the fundamentals of how a motor functions

 

You all are saying the LS1 is faster, but is it a lot faster or just a bit faster?

 

You guys missed the 'for obvious reasons, sono onesay anything.' portion! [&:]

I was just throwing out sarcasm, just like in that thread which addressed another forum with a member saying an lt1 is only a half secondslower than an ls1. lol. Who else remembers that guy? [8D]

 

probably double post, sorry.

The ls1 is much better. The best stock time for an ls1 is a 12.8, and generally they range from 13.0-13.4 (ls1 guys will be able to confirm/correct this.) A stock lt1 will run at mid/low 14's, from what I've witnessed. I want to get mine to a track though, to test it. lol.

 

u talking about the firebird forum i linked to with the "anecdotal" information? [>:]

 

That's the one, lol.

I've never seen the word anecdotal come up in one forum more times than that. lol.
