s10 v8 swap project

HI,
I've been looking around for an s-10 to use for a 350 swap. I found a 1998 2wd 4 cylinder for sale with 139000 miles, it also has a 5-speed manual. How is this truck for a v8 conversion candidate?
thanks,
mike

Re: s10 v8 swap project

Hi,
From what i've read so far, the swap is easier if you start with a v6 s10. The stock 5 speed tranny in a v6 s10 is good for the 350 swap; where the stock 5 speed in a 4cyl wont hold up. Also on 98+ s10's, i've read its much less expensive to modify a v6 wiring harness then it is to modify a 4cyl wiring harness. Plus, all the stock accesories( alternator, ac, power steering pump..etc) for the 4.3 will bolt right onto the 350, where as the 4 cyl accesories will not.

dude piss on all those factory accessories... do like what im doing...

mine is a 98 2.2 5 speed. i took the factory underhood fusepanel and took the wiring for the blower motor, engine harness, airbags etc out and ditched that stuff, simply unbolted it from the bottum. I took and untaped and unloomed the factory fuel pump and transmission wiring, and gutted the wires out of that harness that i didnt need. I'm doing a carbed v8 swap, maintaining factory lighting, and fuel system, just regulating it down with a regulator. im also going to be running the factory wiring for the starter also.

my truck will still function as it did before when i get it all swapped over, i plan on using a nv3500 5 speed transmission and using the same interior console i had before. my truck will still prime and all when i turn the key vs on block fuel pumps that may be slow to pick up etc. I will still have many factory things used, just without all the computerized engine stuff.

there isnt really a specific s10 that is best for the v8 swap, personally i like second gens better, as they are not as common.

Re: s10 v8 swap project

That is an easy way to do it, but I still want to have a fuel injected engine when i'm done. Even though a carb'd v8 would be easier to work on and tune, I want to keep fuel injection.

Yea, a lot of people are that way...

any particular reason you want to have fuel injection over a carbed setup?

Re: s10 v8 swap project

Its a cold morning, -10 degrees out, the daily is broke, your almost late to work, s10 has to be drivin, luckilly, its fuel injection, so he turns the key and away he goes.


guy number 2 is not as lucky as his 100 year old technology is spitting and sputtering and dieing trying to warm up.


LOL ok thats just a little example.

Piss on stock acsessories??? thats a hell of a money saver, why would you go out and buy all custom assesories if you could use an oem setup that works great?

Re: s10 v8 swap project

Its gonna be my first s10 swap, so I wana keep things simple. I want to be able to retain all my factory accersories, plus keep fuel injection for driveability and fuel economy. This is a vehicle that may get driven to work a few times a week. As far as the show and go question, a stock vortec 350 with 255 horsepower will give me all the go I want right now.

I never had that problem, just take it easy for the first 10 minutes in the cold weather. Just because the technology is 100 yers old, doesn't mean the equipment is.

Re: s10 v8 swap project

Oh,
And another reason for fuel injection is that I want the the truck to pass a Pennsylvania emission and inspection test. I dont think a carb'd 350 would pass the emissions unless it was a lick'em and stick'em. And it wouldn;t legally pass a visual inspection of the emmision equipment.

Re: s10 v8 swap project

Just curious to see what s10's people started with( 4cyl, v6, 4wd, 2wd) and what engines they put in them( 5.3, 5.7 vortec). Just lookin to draw from other peoples experience here, any do's and don'ts would be greatly appreciated.

yea, good point...

but i did explain some of it.. oh well..

im only using a few of the factory accessories, they arent really accessories,but i mean guages,and what not..

meaning piss on factory wiring, and fuel injection etc...

im going with a chevy 1 wire alt, if its spinning its charging , edelbrock water pump, and just an old school stock power steering pump, and adapting the lines to fit my stock s10 steering box -

i want simple yet effective. Keeping the factory cluster is my goal, by using factory oil pressure guage, temperature, volts, and speedometer.

and dudes hating on carbs and stuff saying they are unreliable, my buddies dad has a carbed 82 s10, it starts up perfect on cold mornings...

chokes work wonders...

and here in my county, i dont require emissions, or visual inspections, if i did my truck wouldn't pass for shit, they'd notice my suspension, and exhaust etc etc, and fail me instantly. haha..

Re: s10 v8 swap project

I am the same....I am about to do it with fuekl injection on a 2003 Xtreme Blazer. I just cant find any information on wiring int he motor with the computer.
I also want to use the L31 motor. I dont know if it has a distributior or how thats going to work. can anyone help me with the wiring. All I care about it is that the factory gauges work. I want it looking stock until you raise the hood.
Does anyone know what harness I need from the motor I get and how to splice the wires together. I just need to know what wires to connect where.

89 s10 blazer with a 4.3/A4 combo

now im running a 98 vortec 350/m6 combo ran off a 2002 LSx based pcm with an 02 express van OS for the engine and a camaro OS for the transmission.

i grafted the factory 98 harness with the 89 harness and everyting works and looks like stock.

Re: s10 v8 swap project

Hey is it possible to change just the injectors? Just like changing needles in the carb? I had a gmc jimmy that was a 95 and it had the spider injectors. They were all conected. I believe you can on the newer 4.3's. I dont know about the newer V8's.

you can replace individual injectors on the 96+ fuel system

I BEG TO DIFFER it has been proven time and time again more power can be made by going carb'd only reason people go from carb to FI is driveability.

Re: s10 v8 swap project

Where exactly is this proof that carbs make more power than efi????

Are we all driving top fuel dragsters? No, stfu. Efi is going to make more all around power.

Re: s10 v8 swap project

You can do a quick google search and get some good material on the subject im sure.

Bottom line is if you got an average street car and slap a carb on and someone else gets a multiport setup the mpfi system is going to make a better overall better power curve.

Re: s10 v8 swap project

I'm sure you could too. Bottom line, carbs can make more power across the rpm range. The two systems work on different principals, the carb atomizes the fuel with the venturies and "fogs" the fuel, the FI sprays it under high pressure into the airstream. FI meters fuel more accurately, carbs in general don't distribute the fuel as evenly to all cylinders, but that can be partially compensated for with staggered jetting.
Carburators cool the intake charge by vaporizing the fuel at the venturies, FI doesn't, and on and on, etc, etc......
