Not saying one is better than the other. Happy trouble free Hemi swapper here. Pretty much plug and play. And cheaper to swap in than an LS. Never had any issues. 505 stroker seems disastrous from what I have read. I considered a supercharger but soon realized for not much more dough I could have a V8, so that’s what I did.

At the time of my swap, the install kit was significantly less than the advertised price of an LS kit. I could not find a motor and transmission combo(LS) that was as inexpensive as the $3k I spent on my complete dropout, that came with a transfer case that I was able to sell. Prob could have paid less but the poor 19 year old kid and his GF were expecting. A child and I could not do that to him. Seemed as if the LS required many additional parts that were not included in the kit. Was not plug and play, at the time. In my opinion the 5.3 may be a 300k mile engine but I felt as if to get the 400HP of the Hemi I would have to pour more funds into the 5.3 or go 6.2, 6.0 which made the cost rise substantially. Sure there is tons of aftermarket support, k did not want to get into something I may have to sink even more dough into to get what I expected. My wife has a 5.3 Yukon and it is nothing to write home about. It does get better mileage but not near as fun. I could get 15+ easy on the highway if I had gears a little lighter than my 5.38’s and 37’s. 60MPH or less just under 15 easy, get to 65 and that is different story. 4.88’s would improve it I am sure. But I am very happy overall with my swap. I still grin when I hear it start. After selling the old parts I have about $6800 (8700 before)in it. Among others I believe it could actually be done even cheaper especially if you can do a little fabrication yourself. This was my first experience with anything remotely even close to something of this magnitude. If I had to it over again, I would have installed the 6.4 headers right off the bat. Eventually I will install them, they have been on my toolbox for a year and a half. Also, I have yet to see an LS swap thread where anyone says they have that far south of $10k in theirs.
