considering ive built both it cost me more money to build an ls1. but dollar to dollar ls1 will make more power. spend 1k on an ls1 and 1k on an lt1 ls1 will beat it , however, an lt1 is like a general SBC so if (like it says) money is not limited lt1's will beat an ls1. My.02 and besides lt1 bodies look better.

i hear there is a lack of heads available for the LT-1 my friend is trying to find something aside from the standard LT-4 head. and ive seen what happens to an LS-1 when you put even the most basic boltons on the bitch. i vote LS-1, what other engine do you know that gains 50 hp by cleaning out the ashtray in the car? lol

People are making good power with ported stockers. Have him contact Eric Bradby or Lloyd Elliot. They do it for cheap.

I had a 97 SS LT1 and now I have 2000 WS6 LS1 and I have to say I love my LS1. I had the same amount of part's in both car's and my LS1 had a lot more power. :thumbsup:

Ls1's respond great to mods, giving in the gods engine status but i have done so many tihngs to ls1's helped friends and when building my own engine i found that lt1's are easier to work on IMO.

The LS1 has a quicker E/T than the fastest stock suspended LT1, but the LT1 has a faster record trap speed than the fastest stock suspended LS1

LS1 much easier to work on
Both the LS1 and LT1 are half under the windshield...that doesn't sound easy to me!

Yeah unfortunately the LS1 is superior, but that makes sense since it's newer. I would sure hope GM didn't digress when creating a new vette motor :thumbsup: I dislike it when LS1 guys act like its total god compared to everything else though...the main advantage is only the better heads over the LT1, and no opti.

So true for ultra high HP applications. I think the LS1 responds better to basic mods just because the heads flow so dang well.

Keep in mind the LT4 head was designed with lessons learned from the LS1 development program.

stock for stock though, LT1 block vs. LS1 block, gimme LS1 all the way. All aluminum, 6-bolt mains, better oiling, etc.. It's a no-brainer.

I have owned both. I liked the low end grunt that my LT1s had but the top end of the LS1 rules. Since I only mildly mod, I like the ls1. It's definately easier to work on too.
