Making the switch?

[chris1htx]

Hello all. So I've been thinking of making the switch to an LS engine. I currently have an inline 6 that has become unreliable and I just wanted to switch to something that I could depend on.

When looking for an engine, what should I be looking for? I'm looking to get a 5.3 out of a junker or wreck. Is there a certain year I should be aiming towards? What mileage should I keep it under?

Are there any reputable places in Houston to get an engine? Or shops to make the swap? Without spending a bunch.

Any help would be greatly appreciated!
