LT1 vs LS1
http://batonrouge.craigslist.org/car/488385034.html has a newer LS1 style fron end on it too.
Is the LS1 a superior engine? Yes. in almost every way. I still love my LT1 though, I've never owned an LS1, but I know my engine has almost 90,000 miles and 15,000 of those were from me. I have driven the pure **** out of it, and it's still driving wonderfully. I'm not saying I've never beaten an LS1, but it's rare. More common than not, I would say it's because the LS1 guy couldn't drive at all (because I'm not THAT experienced of a driver to begin with).
So like Powder99SS said, it's all about personal preference.
Hope this helps.
by the way here is some lt1 info

And highway runs are a night and day difference. Now just make sure you get the model and transmission you want. Don't settle for a A4 Z28 if you really want a M6 WS6.
Good luck.

My brother has a 99 z28 6spd...and I dislike it for that reason.
That reason alone. Otherwise, I'd have one in a heartbeat. I just think the LT1s are better put together. For a streetcar/DD, you can't go wrong in either. They feel similar, the LS1 just pulls harder up top, but I like the drivable TQ of my LT1 and is alot more fun around town.
Buy what you can afford. I have a 5k LT1 with higher milage than my bros 5k 99 LS1. He got a hellava deal...but I like T/As

To get an LS1 t/a I'd have to spend 10k easy to get what I want. You old guys here all about milage, are justifying 14k for a T/A and making the LT1 a far better buy at 5-6k. Higher milage cars can run just fine. My 155k lt1 screams all day long, as does the 130k z28. I just enjoy 3:42s more than 3:23s

I agree that there are a lot of high mile LT1's still running strong. But now that enough years have passed we are seeing some 100K, 120K and even a few 150K ls1's running just as strong. I don't think longevity is a problem with either motor if taken care of.

But they are cheap. Which brings me to a couple of old sayings:
1). You get what you pay for.
2). If something looks too good to be true it probably is.
There are a lot of scammers out there trying to rip you off so be careful coonass350. Good luck and happy hunting.
