First where was the last misinformation, secondly once you factor in driveshaft, motor mounts, exhaust, harness modification, fuse block, PCM tuning(NOT JUST A DATA LOG) ,the intake, flywheel spacer, cluster modification, fuel tank, fuel pump and return or returnless system and misc expenses you are into your swap about another 2 grand all said and done. That is a properly running, emissions passing/safety certification (depending on state) LS conversion. Not to mention the cost goes up if you decides you want to upgrade any part of the engine or exhaust or if you are doing the conversion on a 4x4. Some of this obviously depends on how much you get the initial engine and trans for but I am into three of these conversions now and can speak from experience. How many conversions have you done gramps77?

My first was a 4.8 on a 73 fj40. That was a hard learning curve. Much more involved then we though going into it and turned out nice when done but was a steep learning curve.
Our second (my partner and best friend) was a 71 C10 swb that we flipped for a quick buck before it was completed to finish our 72 (frankensteinish) K10 with a LQ4 6.0L. My 5.3 I have sitting on my stand is reserved for my 84 K5 that when the original 350 gives up the ghost. So technically I am on my forth conversion and people think they are cheaper then they really are especially if they don't have a complete engine, trans, harness and fuse box. All of that adds up and slows the process WAY down. At least it did with us. Can it be done for under 5K? Sure but you must not get the mod bug and be extremely thrifty and crafty in what you start with and how far you want to take it. Obviously starting with a vehicle that is already FI is a plus and something that can make life a little easier both on the fuel and speedo side of things depending what you go with.
