I've looked everywhere. You got an absolute steal. Everything I've found is going for 3-5K depending on the damage.
groundshock said:All fine and dandy, but no doubt you're probably maxed out on the 4.2, or at least getting into diminishing returns. LS based 5.3, well, sky's the limit.
Dollar for dollar, the V8 is the better option. No question.

Pittdawg said:Don't get me wrong a 5.3 swap would be sweet but there are plenty of mods available for a 4.2. I'll run against any stock 5.3 and whoop it with my modded 4.2.
Several of the offroad guys have done the 8.6 swap. I'm pretty sure it is a direct swap.ScarabEpic22 said:You have to do driveshaft work with both I believe, I know the 9.5" needs a shorter driveshaft but cant remember if the 8.6 does (I think it does)......
northcreek said:Maybe but...it will still sound like Grandma's car while doing it
groundshock said:Wonder where a guy could look to find a rolled 03-05 V8 EXT....
Jkust said:Plus I don't think it'd woop it so much as keep up with it in some spots and slightly beat it at the margins...thats of couse assuming the 5.3 owner hasn't attempted any mods. There was a thread a while back of someone who had a modded 4.2 and a stock 5.3 with some fun comparisons.
mikekey said:Not everyone interested in this is doing it for driving around racing. I'm interested for off road and towing applications. My wife and I would like to tow an airstream up hill faster than 55mph thru the rockies.
Let's try to keep the thread closer to discussion on technical aspects or we'll end up with a thread like the TrailVoy with 15 pages of guys going back and forth about their opinions. You've given us yours and why people should stick with the I6. We appreciate it. Now lets discuss what needs to be tackled to accomplish the swap.
Jkust said:Well, I'm responding to the the other post comparing the performance of the two. I just want to see someone do the swap since it is will go down as a legend. We've all piped in on a dozen of these and nobody has actually attempted it.

C-ya said:I went the low tech route when I put a carb'ed SBC in my Hombre (aka S-10/Sonoma). Lost anti-lock brakes and factory speedo, but whatever. Were I to do it again, I'd get as much of the harness and controls from a full-size that had a V8 and use a newer engine that was FI. It was out of my budget at the time.
Good luck with the project if you decide to take it on. I think it would do-able since, like was posted earlier, it was a factory option in these vehicles. It's not like you are reinventing the wheel here like I did. The S-trucks had the 4.3 as their biggest engine option.
MikesTB said:I have a 96 Silverado that had the 5.7l vortec in it but I spun all the bearings in the cam and crank beyond repair so I dropped a 1980 carb 5.7l with a 2 speed powerglyde on the back of it. That's the only other engine I had to put in it it was a pretty easy conversion.
eutechnyx said:Not to argue or be a butthole but I would say a v8 swapped s-series is so common and ive done 2-3 of them myself that its nowhere near reinventing lol. There is SO many parts available to make that the easiest and cheapest swap you can possibly do in an s-series. Honestly IMO,this swap is more re invention than a carb'd sbc in an s10 lol.

I've seen threads with people who have done it, but they bought a donor SS and literally swapped everything. But I have yet to see a completed non-donor vehicle swap with just the engine. I'll do another search again but if I don't find one, I'll just start another thread with my build.
