Doing the actually physical swap is fairly easy. Since what we have is basically a 350 V8 with 2 cylinders chopped off, almost everything bolts up. You may have to scrounge junkyards for some brackets, etc, but from what I've learned, it's almost a bolt in for a 350. Now, the electronics and of course those pesky emission controls, well that's the hard part!

I read somwhere that the later model S-10's are easier to drop a V-8 in more than the early models due to design and also has a stronger frame design. Dunno how true it is.

Check out http://www.jagsthatrun.com. They have some interesting stuff on S-10 V8 swaps as well as how to stuff a V8 in a Volvo (that would be a fun sleeper).

Myself, I think the 4.3 in stock form has plenty power for me. And when you put a V-8 in there, the increased weight will have to be delt with also.

I've read JTR's S-10 V8 conversion book cover to cover. :shock: There is allot of info there gained only from experience. They say the Vortec supercharger on the 4.3 is less expensive & will create as much power as most FI V8s. BUT it will still sound like a stinking 6 banger. I have researched extensively the V8 possibility, the amount of time & effort to do the job right :D I consider a V8 in anything older than a 98 a waist of effort. :roll: To do a clean installation a donor vehicle is absolutely necessary (Rolled 98 Camaro or full-size truck non-TPI is better TBI is what makes ease of installation & stock air cleaner box is still used). To be smog legal the matched exhaust components should be used including trans & ECM from the same unit, don't use a corvette motor you'll never finish the job...all engine accessories are at the wrong location. Also the fulltime 4WD transfer case from a Bravada or Astro van are needed to get that power to the wheels. :thumb:

How about the Lingenfelter Sonoma with the LS6 in it? That looks like a nasty little truck! Of coarse it's a $100K conversion.



Once I get my Camaro project complete, I plan on doing the 350 conversion on my 91. I have a '96 Lt-1 sitting in the garage. Just another fun project!

well, isnt the LS1 350 hp or something...if so, that is better than the 4.3 with super charger, right?

LS1's in the F-Bodies are underrated at 320 HP...they're more in the 350-360 range based on dyno results I've seen. My 99 Z28 made 310 HP at the rear wheels (figures to about 380 at the flywheel) with just intake and exhaust. It got great mileage too...never less than 20 mpg even in stop and go traffic with a few runs down the 1/4 mile.

i have seen new f-bodies with stock LS1 run 12.5. i would think there would be more than 320 hp in that motor....there is that guy that has a LS1 motor in his zr2 that has the DBS 5" with 33's and he was running 13's....of course he did have nitrous :wink:

Yeah...there's a few factory freaks here and there that run 12's stock. I've also heard of a few that run 14's stock. But the vast majority run mid to low 13's right off the showroom floor, which puts them basically equal to the Vettes, which are lighter and rated at 340 HP (non-Z06 that is).

Now this is what Im talking about. My first S-10 was a 1982 (first American model year) the Isuzu 1.9 that was in it just wasnt working. I decided to build a 377 stroker for it (400 block, 350 crank and rods) after I finished building the engine, rebuilding the TH 350 trans, getting a new drive shaft made for it, and getting my hooker headers in the mail, I was ready. 2 hours, a few swings of the sledge hammer to the firewall, and I was backing out of the garage with the quickest truck I ever drove. To bad its so hard to do with the new ones (especially 4wd). I will have to see if I still have any pics of it and post them.
