I can pick up a Junkyard LS in good condition and including the harness for $250 -500, my brothers was a prime example(6.0 from a Yukon for 250), wiring harnesses are much cheaper to purchase/modify for the LS swaps than with GEN III($1100 for a hotwire harness is). I can get an already refreshed turbo 350 for less than half what it will cost me to get my 904 rebuilt or pickup a freshened up 727 to bolt to the GIII. Headers for the GIII, $700 from TTI or can be had new for as cheap as 450 for s10 mid length. LS swap information is much more readily available and people are more willing to share the info on the swap. I literally asked a question to two people, and 30 minutes later I had an entire list of just about everything I would need for the LS swap, everyone who has done the GEN III swap seems more standoffish about sharing too many details or a shopping list. So you spend 6 months or longer digging through threads and asking 50 people for help info, and trying to piece it all together on what you need for the GEN III swap. Use the same k-member and mounts I was going to use for the GIII swap. I can get the junkyard 8.8 for maybe a couple hundred have it shortened and ready to go for what it will cost me just for the dang pumpkin for a 8 3/4. But I can literally save a few thousand dollars just on the engine/harness/trans/rear alone. I can relate this LS vs GIII to when I stepped up from a 1991 Eclipse GSX to a 2003 Lancer Evolution, still a 4g63 motor powering both cars, generally the same design as far as drivetrain goes, but the mere fact it was for the newer Evolution meant there was like a EVOTAX you had to pay for all the parts. Most of the time double or triple what it cost for the DSM 4g63. I understand the purist mentality, but with the way most of the MOPAR world seems to be with sharing info on the GIII, we're way behind the LS power curve(pun intended) in that regard. Just my 2 cents and based off of what I've found near me/available to me. Everyone's story will differ slightly as always.
