If you decide to look at the 454 GM crate, check what version block they are using, and try to get a gen VI block. Its worth extra money so if it costs extra, spend it.
On Edit, that would be 1996 and newer ie L29. It should still be a nearly bolt in deal still. I don't think they went to tall deck until after 2000. Tall deck just means a different intake manifold. '96 also means it has vortec heads, which I believe are fast burn. This also means significantly more HP as well.

And then click on spec sheet.
3 years 100K mile warranty, which should be the sames as Jasper. For comparison, you want to also make sure the warranty is valid if installed in a "truck". This voids some warranties, or shortens the warranty.
I should also mention that CrateEngineDepot is where I bought my 502. They were very good to work with, as I had to change my order after I bought it. I picked it up, as they were only about 30 miles from my house.
