If one was to want an LS motor, what year and models are the most "bang for the buck" friendly ?

I am thinking about a new project

I have researched alittle on the subject and have decided that is the route I am going wtih my Chevelle. I plan on picking up, as a donor, a camaro or firebird with a LS1. They seem to go for about 3500 bux at west coast wrecking yards but they perfer to not sell the complete car. I am after the whole ball of wax because the possibilty is I might also need the rearend, drive shaft, etc. and of course I will need the computer and looms.

I am not even considering a Corvette donor due to the trans/axle situation.

The key for me is finding the right donor ...... its gonna be fun. The finished car is going to be fast, comfortable, reliable and high tech.

Are you looking at getting the most power for price? The 6.0L LQ4's can be found cheap and with a set of L92 heads they can make upwards of 500-550hp.

Is weight important to you? Iron blocks are a lot cheaper than aluminum.

Weight won't be that important but generating power and reliability will. Thanks

I should have mentioned that budget is very important.

I bought a COMPLETE LM7 5.3L with 47K miles out of a totalled Z71 pickup for $1000 last August.
Complete "dropout" with all front accessories (alt, A/C, PS, belts, pulleys, brackets, fan), exhaust manifolds, starter, full uncut harness, DBW throttle body, and matching ECM.
Bought from Ebay...a fresh pair of -241 heads w/sodium/hollow valves, pushrods, and a healthy custom ground Comp hyd roller cam. Heads are already setup with correct springs for this .600" lift cam. Paid $600
Purchased from Summit...Edelbrock RPM carb LS intake and MSD 6010 programmable stand alone ignition box. With such a wild cam, I'm figuring it's not going to be too fuel injector friendly...hense the carb setup. Cost $630 plus the Demon 650 carb on hand.
Bought the GM muscle car oil pan kit, new lifters, a conversion flexplate (for TH400) and gasket kit from GMPartsDirect. Cost approx $220
Fuel will be supplied by a Holley 140 electric pump already on hand.

All this should have already been installed in my Chevelle but the project is delayed due to injury.

All extra, unused parts...-799 heads, complete truck intake, DBW assembly, harness, ECM, exhaust manifolds, etc will be sold to offset the initial cost of the engine.

Whats the new project gonna be ,you need a 68 Malibu to experiment with ?A 55 Bel Air 2 Dr Hardtop ? Or you could just put it in my old beater truck and I could tell you how good it was.

I would love to do a supercharged late model Malibu or Elky. Problem is cash. Was thinking more along the lines of a slammed, 79 Malibu with a bad ass 5.3 Vortec in it.
