The Lt-x has no aftermarket support for larger displacement block castings. Cylinder head options are limited, intake manifold options are lmited, ignition system is a bit more of a pain in the a$$. Aside from the 94' and new c4's the tuning software is essentially the same primative stuff as the earlier c4's.

Keep in mind the above statements are for "off the shelf" stuff. So, of course you can go out and get stuff custom made, but why?

The L98 has a monsterous aftermarket! You can get aftermarket blocks and build a big-inch small-block... go mild to wild as far as heads and intakes are concerned (more specifically, the 18 degree heads-if you want somewhat similar technology as the Ls-x).
Thanks for info.I didn't know the l98s had alot of aftermarket options.I do know that you can buy a pretty bad-*** crate engine for $8000 or have someone on this forum build you one.I've read about forum members doing some amazing stuff with there "stock" engines-crossfires doing 13 second quarter-mile etc.I would recommend keeping stock engine & just upgrade it with bolt-ons etc.I would hate having to deal with wiring harness cutting & splicing.Plus its very time consuming.
My opinion is why not have someone here tell you what to do to make you car/engine fast.That way you will only have to deal with engine/driveline.Not engine/driveline,fabrication,wiring,computer,fu el lines,throttle cable,diagonstic connection,etc.I think putting a different engine in is a cool idea but should be done correctly & this involves alot of time & money.By the time your done you could have bought a mint c4 or even a c6.I'm sure you can do it cheap but if taking on a project of this magnatude,do it right.This will take alot time & money unless its going to be a stripped out car with a jerry-rigged wiring harness.

to the op, A truck enginge is fine. Just some things to consider..intake, drive acc, wiring. think about the whole swap. make a plan and stick with it. Look at used parts if your on a budget. Ask lots questions, learn as much as possible and the swap will go fairly easy. Lots of good stock take off parts can be bought for nothing. I decided to go with a truck motor. I had 6k to spent total. That will make a nice l98....but I sat down and done a lot of thinking over a couple weeks. Added up a few parts here and there and decided i could make 500rwhp with the 6k if i bought a truck motor. At the moment I have around 5k in my swap and basically all I like buying is fuel system, wiring, and a gas pedal.

how about instead of follow peoples advise, do some research of your own, talk to PROFESSIONALS and decide what you want to do with your car.

According to LT1396corvette: LT1's are waaaaaaay better than LSX engines. that must be why GM is still producing them and sticking them in every car/truck they build.
Where did I say that.Quote me.

You indirectly stated that LSX engines are worse/no better than LT1s.

If LT1s were so great, why isn't GM still making them

I only suggested that the person posting this thread talk to people here that have a fast l98.You can talk to professionals all you want but my opinion is talk to someone who has made their car(l98) fast.I'm sure people can give good advice on how to upgrade the persons l98 with the engine swap money & will save that person alot of headaches.But if he does go the "truck motor" swap I hope he posts pictures of the process

FWIW the latest GM High Tech mag, has a article on using the LS1 pcm for tpi cars. I just got the mag in the mail yesterday and have not read it yet, but its on the front page.

If anyone is looking for a LS motor, I seen this one on craigslist. I do not know them or anything about it other then the ad. Again, I was just scanning craigslist and seen it.
