LS1 is old tech.
Go with either a LS6 which came in the C5 Z06's in the '02 to '04 models, or better yet a LS7 from the current C6 Z.
A low mileage LS6 can be had for bout 5K, and LS7 for about 9K. GM crate LS7 motor are about 14K.
For example, with a medium cam, exhaust, intake and a tune, I've dyno'ed 530rwhp with my LS7. Haven't touched the heads yet.
Both can be modded to add 100rwhp with heads/cam, and get you 28mph on the highway. All depends on your budget, and how much power's enough for you. (If there is such a thing).
