hey guys thought I would post this up here for you s10 guys since so many of my parts are out of an s10 now.
my build is a 1980 chevy luv 4x4, came with an Isuzu 1.8, the previous version of the early s10 1.9 and a 4 speed trans. I drove it that way with a weber for a couple years, trashed my transmission and pulled the engine and tranny.
some pics of the process so far.
stripped down, note the big kink in the core support... damn rangers....

engine coming out, sold it shortly after

trans/case coming out. scrapped it since it wasn't worth selling

stripped the interior, putting in new gauges, seats, dash pad and custom dash face.

pulled the entire harness out of the cab and engine compartment labeled and started cutting out the extra crap and stripping the engine section to wire in the new sensors and such for the new motor


bought a jeep xj "power center" relay and fuse block, goes wired inline with the battery and alternator seemed like my best option for a retrofit and custom interior

bought a 91 4.3 v6 from a s10 blazer, stripped and scrapped the heads, intake manifold, exhaust manifolds cam oil pump... everything but the block crank and rods. had it bored .030 over, hot tanked, checked deck for flatness etc.

had the crank ground .010 and .010

went to the junkyard and pulled a pair of 97 blazer vortec heads

started off really gunked up

used a poly abrasive wheel to clean the head surfaces

and a set of wire wheels and cupped wheels to clean the chambers


ground the casting faults and burred edges off the block, less places I have to bust a hand open the better :haha:


bought a blazer nv3500 4x4 5 speed from a guy who parts them out here in Vancouver


got a set of bolt in mounts and isolators for the 4.3 from Power By Ace

getting the 4.3 ready to put back together, got a full rebuild kit

dropped the new mounts in right after I cut the old exhaust out

bolted the oil pan on the bare block to see if it was going to clear the stock diff

went in like butter looks like it belongs in there

plenty of room in front for a 19x22 aluminum radiator and electric fan


that's all the pics so far. just got my new cam bearing tool today so I will be doing the assembly of the shortblock tomorrow when I grab some assembly lube and rtv.
still need to pick up an edelbrock 2114 intake manifold,
set of pacesetter shorty headers planning to go with dual 2 1/4 pipes Y-ing into a single 3" pipe straight back to a flowmaster super 44 center in and out, no cat.
a holley 450 4 barrel since its equivalent to the tested and proven 600 on a 350
comp cams roller cam, trying to decide between a 260AHR or 266HR
hei distributor
clutch set
and a bunch of wrench time and interior work.
painting it metallic sapphire blue with bed liner and bedliner on the floor of the truck, tinted plexiglass backlit with blue leds for the gauge cluster I think the exposed wiring will look good back there, same for the blue led backlit switch panel on the dash/console face, need to make new door panels and center console after I modify the tunnel for the transmission.
Fitting 85 Isuzu trooper vented, drilled and slotted discs and trooper calipers on the front. working on finding a rear end that matches the front 4.10 with lsd, may do a ford exploder 8.8 or older rx7 rear, either way I want limited slip and disc brakes. need to decide between irs and straight axle
going to be a fun couple months :D let me know what you guys think. and any recommendations on the cam choice!

Very cool! Surprised you didn't get flamed for not doing a v8. I went from 2.2 to 4.3 in my s10.

thanks guys, cant wait to get it together and back on the road.
I have nothing against a v8 swap but up here in Washington we have things that we call "corners" and "river roads" :haha: trying to save weight up front, moving battery to the corner of the bed behind the passenger seat, relocating gas tank more rearward I want it to be well balanced

and here are some before pics of the truck



old motor, weber 32/36 electronic distributor swap, redone head etc

when I first drug it home

I cant say I was a big fan of it either... it was done 2 owners ago, the driver side is half sanded down I got the surface rust spots off the bed. bought a jug of paint stripper so after I fit the new crossmember and mod the floor for it I will strip it do the body work and tow it over to maaco to have them spray it. getting a metallic sapphire blue so I want that sprayed professionally

got a little bit done on the 4th before the fireworks
had my buddy bring over his pressure washer, rolled the truck into the driveway sprayed out the engine compartment, front suspension and the transmission tunnel


as you can see the luvs have a passenger side front diff. im going to need to pick up an adapter so I can mount a psd NP208 transfer case, keeping with the aluminum and light weight plan.


while I was at it I pressure washed the hell out of my cylinder heads in the water jackets, around the rockers and springs. popped them on the block to see how its going to look.. I think its beautiful :) but I still need to take a dremel to the jagged edges in the lifter valley there.. just looks ugly


tapped all the head bolt holes, main bolt holes, and the oil pan and timing cover bolt holes... spaced out and dropped the tap thru a head bolt hole into the water jacket.. thankfully it came out of a freeze plug hole without much of a fight.


popped in a few of the freeze plugs before I took off to enjoy the 4th :haha:


that's all for now. I need to order another set of cam bearings because one of mine got messed up :( along with some new head bolts and a transmission mount so will be waiting on those while I get some of the interior work done. I need to come up with a nice pair of seats for it and cover them to match

real quick update, got my new pistons pressed onto my rods, picked them up today



also ordered intake gaskets for the 97 heads, new head bolts, a bosch "heavy duty" water pump with new studs, a thermostat and new cam bearings cuz i screwed one of mine up.
i just need the edelbrock 2114 intake, the compcams camshaft and a holley 450 carb. so around $600 for the rest of the motor.

i need to either sell this transmission and get one with the right bolt pattern for a np208/np242 or buy a new gearbox/tail housing with the right pattern. this 5 bolt doesn't mount to any psd case i have found.

I think a 4.3 will be awesome in this truck.
few parts showed up, bosch heavy duty water pump and studs, thermostat, cam bearings (I scratched one of the other ones), 97 intake gaskets.

I got the expansion plugs installed and drove the new cam bearings in

popped it up on the stand for assembly

used some carb cleaner and a no fuzz rag to clean the rust proofing coating off the crank

plastigauged the main bearings

broke out the assembly lube and got the main caps installed and torqued down.


just need to pick up a piston ring compressor so I can finish the rotating assembly. ordered my cam from CompCams went with the HR270
http://www.compcams.com/Company/CC/cam- ... d=560&sb=2
will have that on Friday and will have it installed over the weekend.
now that I have my intake gaskets im going to break out the dremel and match the ports to the gaskets and smooth them out.
just need to order the ls2 valve springs and the edelbrock 2114 manifold and the motor will be done.
selling the 5 speed and I will be hitting picknpull for the right 5 speed and a np208

after bashing a knuckle on the jagged edge once I would feel like an idiot for not doing it :rotf:
I will have to see who is recommended locally for the paint, may have to wait on that part until tax returns come around again. im dumping a lot into redoing the interior, motor and the drivetrain as it is, may give it a quick gloss white job for the winter with my detail gun :haha:

anyone know a good donor for some light weight bucket seats with decent side bolsters? I kept the stock rails so I can make them work. my stock seats were shot, springs, foam and cloth were done


so I have been doing a lot of research into megasquirt efi systems. being that they are gm sensor based if I was to get the ms3, a few mostly stock sensors with a ls type throttle body and an o2 sensor in a pacesetter shorty I can run sefi with the edelbrock manifold with some injector bungs welded in.. not doing it right now but I will start gathering up the components as soon as I get it running with the carb. I like being able to mess with the settings to get it dialed in perfect.

you probably want MS3, i dont think ms2 will support more than 4 sequential injectors, unless you run em in batch mode

yep ms3 is the only one that will do full sequential on a 6-8 cyl, once I get it running I will get started on gathering the parts I need for the ms3 and the ms3 itself.

pistons and rods are going in tomorrow afternoon if I have time before work, if not they will tomorrow night :haha: when the cam shows up I will do the full assembly water pump, timing set, oil pump, etc.
ordering my intake and carb this next week, pending sale on my trans so i should have the right one and a case in the next week or two, mock everything up and get going on my interior

so my nv3500 sold.
im trying to decide. should I get the nv3500 with the right bolt pattern for the case I want or should I go big and get the nv4500? is the nv3500 really that weak?this motor should have no more than 300lbft I would think. im probably going to weld my diff until I get a limited slip rear end over the winter

yep the 2wd is around 2400# so im assuming im going to be looking at 2700#. without the emissions junk, a/c, power windows, power seats etc they end up being a ton lighter.. all that extra weight is not welcome in my rig :haha:

I figured the 3500 would be safe since it will break traction long before I break something solid.

I need to work out my suspension. I am going to pull the front torsion bar and put in coilovers in the stock towers with a bit of reinforcement. I am hunting for an independent rear end with disc brakes and a 4.10 gearset. I know an older rx7 has one about the right width with lsd and 4.10 but beyond that I don't know of any. thought about a supra rear with a gear swap since they are so strong

exactly. even if you dont break traction less vehicle weight means less tranny stress. weight matters just as much as tq. when it comes to driveline

and id be worried about an rx7 rear. they can be built but are really expensive. the aftermarket lsd options are pricey too. the factory clutch style works wel if you find one in good shape. but if it needs clutches, I have never found a kit less than $350.
