is the LS iron block V8 made by GM about the cheapest junkyard engine out there?

Completely depends on what motor you really want.
4.8 and 5.3's are the cheapest to find. The 6.0 in either the LQ4 or later LQ9 are the most expensive GEN 3 motors out there, upwards of $800-$1200+ for a decent mileage unit, they are sought after for the power they can make. Any aluminum 5.7 or 6.0 are just stupid amounts of money too.
Stock for stock the 4.8 and 5.3 already make more power and have modern fuel injection with way better computer controlled systems.
A 350 bottom end can't handle as much power in stock form as the LS series motors can. It would cost so much to make the 350 worth anything, like making it a 383 stroker. Or you could put a nice cam with supporting mods in a 5.3 and come out way cheaper.
The 96+ vortec heads are the best stock flowing heads for a 350 but the LS heads flow better stock for stock. And AL heads for a 350 cost over $1,000 I think where as the LS already has aluminum heads.
Lm7 + turbo or nitrous. Nuff said

I have a low mile LM7 i've had for a year or so that is at my father in laws and will be going into either a fiero or 98-02 f body. Cam, 243 heads, headers, and nitrous could easily get 450-500whp, my personal goal.
The Vortec 5300 LM4 (VIN code "P") is an aluminum block version of the LM7, and had a short production life. The LM4s made 290 hp (216 kW) and 325 lb·ft (441 N·m), It should not be confused with the L33 described below.
LM4 applications:
- 2003–2004 Chevrolet TrailBlazer EXT
- 2003–2004 Isuzu Ascender
- 2004 GMC Envoy XL
- 2003–2004 Chevrolet SSR
- 2004 Buick Rainier
