Sy-clone build

[s_blazin]

well to start off i have been collecting some info for a couple of days now, also am picking up the transfer and front diff tuesday.

still got a frame to find and finish the sonoma GT interior harness swap. will provide more info soon but this was just a quick start because i have to work early tomorrow.

anyway might be picking these up off my dad, they're from his pewter 98 C5. they don't stick out at all, being stock height in the front, lowered may be another story though.


Sittin on the parts blazer

thats your parts blazer? Damn you guys really do not have rust out there do you. Good luck on the swap I did a similar swap on a second gen.

PROPS TO YOU, SOUNDS AWESOME, got a build thread?

no we really don't have rust issues in OR unless you do something to it to envoke rust to start.

i may have (no, will have) some questions to you guys having done this before.

by the way this blazer was MINT except for a bad 4.3, had serious fuel in oil.

kind of a shame to dissassemble such a nice truck but it does the job for my benefit. I WILL BE PARTING OUT THE REST OF THE BLAZER when finished if anyone wants anything i don't use

Re: 86 s10 2wd v8 to AWD v8 conversion

so since the bravada prop shaft is bigger than sy/ty, i can't run it. thats shitty since i'm running a sy/ty shifter.

suppose it won't matter much till i get the chassis and get the motor in to figure out where it will set and if i may have to have a custom prop shaft made

i have the bravada front diff and transfer in my possession now. need to get time to get back out to the wrecking yard and grab the x-member for transfer and campare the trans x-member to reg. 4x4.

still need to find a donor truck or a rolling frame in or around oregon.

anyone know where the wiring comes from to the transfer for VSS? my truck was originally a cable speedo, VSS must come from the engine harness?

anyone need a 4l60e trans runs through the gears fine shifts are firm? trade for a 700r4 so that i don't have to deal with wiring for the 4l60e?

need a trans and then collection for the drive train will be complete for now.

i'm wondering if the torsion bars on a donor s10 when i find one will be softer riding than using bravada ones?

700R4 is still electronic. 700/4l60 almost the same tranny. You would need a 350 turbo or 400 if you want no electronics.

THere is a box called DRAC which converts the tranny signal into the speedo for mph. this box is ussually mounted on the back side of the bracket that holds stock ecm.

\A 4L60E with no wiring or controller will have reverse and third gear only.

I thought it was 2nd gear..??

thanks Dave for clearing that up for some people, i already knew that because of talking to you.
FYI for those of you that don't know Dave, he really knows his stuff. he has helped me tremendously with my project. i would not be nearly as far with it as i am without his help

Re: 86 s10 2wd v8 to AWD v8 conversion

Re: 86 s10 2wd v8 to AWD v8 conversion

i thought about taking the 2 frames and slicing them both at the splice, as Dave mentioned, and putting the blazer to 2wd front end and the truck to 4x4 front end, one thing i remember form my v8 s10 book i got <(can't seem to find it right now though) on 2wd'snot sure about 4x4's the frame are different in the front on pickups and blazers in that where the frame mounts go it has a different shape to it therefore the engine will sit differently between pickup and blazer.

i remember reading this and they showed comparison pics, wish i could find it now to show you, i'm not sure if the 4x4 is same way but if so that could potentially cause an issue for certain clearances and motor mount placement. i'll have to research it more next week when i'm not working from 6am to 8pm.

Ian:

Really? I've never heard or read this. My JTR book is a 1994 edition, and makes no mention of any differences between Blazer and pick-up. The only "frame mod" they show in my book is hammer in the rear of the pass side cross-member for starter clearance. Not required with a gear-reduction starter.

LMK what you find out with further 'research'.

Dave

my old JTR book was an 02 edition, but i can't find it so i ordered a new one along with the tbi tpi book just for fun. but i remember specifically that they showed pics of the engine bays right next to eachother and the comparison was to show that blazer frames sat higher for some reason.

if i am remembering correctly that this is true, i wouldn't think GM would make variances in frames for no reason so if it were the case i suppose i best go the the wrecking yard and compare and see why they did this.

i suppose that maybe for some weird reason that the firewall trans tunel and under cab must be somehow different. maybe sitting at a different height or something. not sure but i want to figure this out before diving into this project.

i am having a terrible time finding a 4x4 standard cab short box even an old pile just for parts, weird i remember back in high school it was a daily event to scour the yards when there was nothing else to do, looking for little treasures and i remember ton and tons of them at every yard. and now........none at all

i will know more when the new book comes in.

Did you try and fix the gas in the oil problem? If you had you could of sold this to paid for the setup that had what you need.

i have not not attempted anything, only because i din't know where to start...any tips?

the truck can still be put back together actually, just gonna take a bit of time.

i was actually thinking that if i ended up swaping front frame sections that i would put this thing to 2wd and with my belltech kit thats on the s10 frame now it would have a 5in. drop in the front, get the back down some and either sell it as a 2wd OR switch all the stuff from my 2dr blazer over. ALOT of work to do but i am at a loss with it.

this is the other v8 blazer, it is not very nice anymore, it was so clean and stright and perfect then

shortly after the pic, i was working 2 very long hour jobs and on the way home i fell asleep and hit another car, HARD, bent the frame, caved in a section of the roof above the passenger seat. F'd it up bad, the frame was "straightened" but i don't think it will ever be right and the roof is a toughie to fix. so i've been thinking about switching it all over to another blazer, and a nice 4dr is nothing to complain about. it's just a cruiser so i was thinking why not add another door?

it sucks because i love that black and silver thing (bought it when i was 15, 7 years ago) but i don't think she will ever be the same again

Re: 86 s10 2wd v8 to AWD v8 conversion

What engine does the blazer have? Is it the TBI or the CPI ? The TBI look kind of like a 2 barrel carb with the 2 injectors on top if you remove the air cleaner. The CPI has a 2 part intake with a center piece that is held on with two T-20 or T-25 tork screws, this center piece says VORTEC in red if I recall correctly.

Re: 86 s10 2wd v8 to AWD v8 conversion

Re: 86 s10 2wd v8 to AWD v8 conversion

the blazer is a 94, the vortec cover is gone but it is cmpi. i actually have the TBI setup on my v8 blazer, it sucks. nice thing about this blazer being 94 is that the 4x4 was electronic so no hole in the floor for 4x4 shifter. good just in case i do the 2wd conversion

OK, that is good, that engine is really easy to work on. If you have other transportation. heres what you need to inspect.

1. Disconnect the battery neg side.

2. You need to remove the Air cleaner setup, throttle bracket, map sensor, power brake hose from the upper intake.

3. Unbolt the upper intake. I think it has 10 bolts on it. it will take a 10mm deep socket on some. On the pass side you will remove the coil bracket and on the driver side you will remove two supports for the plug wires.

4.Carefully remove the upper intake and put it some where safe.

5. Check around in the lower intake now that you can see it on the driver side back cyl. fuel will amost always pool there.

6. If you don't find any fuel pooling, connect the battery back up so you can run the fuel pump only.

7. Cycle the fuel pump and look for the leak. As this engine only has 1 injector it should be easy to find the leak. The 1 injector feeds what GM called a spider. When anything goes bad you must replace the whole spider. The compete setup cost about $430.00.

8. If the fuel is coming from the supply line or the return line, it is a easier fix. These two lines past thru the lower intake on the driver side of the intake and go to the spider. They are about 12'' long. The kit to replace these cost about $85.00. I forgot to say that the gasket for the upper intake is like $12.00 from Auto Zone.

9. To be on the safe side I would replace both components. After you replace these, check your fuel pressure from the pump. It should be between 58-64 lb. The little poppet valves at the end of the spider takes 51 lbs to operate.

10. Putting it together is just as easy. Go backwards of taking it apart.

Hope this helps.

Re: 86 s10 2wd v8 to AWD v8 conversion

thank you for the info,

i actually cannot start the truck currently as the dash and steering column are out but when i get them back in i will try just that,

on another note i remember the previous owner saying that they had the spider replaced not to long ago.
they were retarded hippies and by the way they came off i did not trust anything they said, but they told me they took the truck to jiffy lube had an oil change and thats when the problems arose, whether this is true or how it could be, i don't know

I would check the oil 1st to see if it is clean. If they were hippies they may put flowers in the crankcase to give the Blazer some love.:tup:

Re: 86 s10 2wd v8 to AWD v8 conversion

well not much progress in the past couple weeks but atleast it's something.

got the manual pedal asssembly switched out for the auto. got the ac heater box on the firewall and the heater core straightened out so it fits properly now.


yes i know under hood looks like ass! when the time comes for it to drive i'll replace the air cleaner with my K&N and extreme lid that i was saving.

also gonna change the valve covers as they are chrome and leak and chrome is ugly anyway, just not sure what i'll do.

i wanted to go with the black crinkle coat with the red chevy logo but i think they come in center bolt only.

heres my clearance, more than i expected, you can't see that well but you can actually stick your finger in there

anyone know what this guy here does? it's tied in with the harness that the heater plug is in, may be provisons for something i don't have

i'm looking forward to putting the interior back together but it seems like it's never ending to get there especially trying to put the dash in...once the doors can go back on atleast the dash can go in.

then comes center console,fun. getting the shifter bracket on will be an interesting task considering i'm not sure wich way to turn. either drill out the spot welds and place the PAS added cover on the floor the way they did, i have the whole cut from another truck, or...i dunno now that i think about it i like that idea the best. just gotta make a piece to cover the remainder of the manual transmission hole, about 1/3 of it shows.

i also need to figure out the rear shifter bracket on the floor, as my sig says, but someone mentioned that it's the same as regular s10 with a center console.

B&M industries is gonna try and snap a pic of a ty rear bracket and send it to me to compare if he gets a chance. but anyone wanna put it out for sure yes or no now?

i'm wondering though i currently have a th350 trans in it now and am not changing to the 700r4 till i go awd so will does anyone think i will have problems getting the shifter cable adjusted enough to get all the gears.

some people i know using the column shift ran their set backwards in a 3spd trans, 1st is 1st, 2nd is 2nd, 3rd is 3rd, 4th is neutral, neutral is reverse and reverse is park, and park is unused. which if you don;'t know that you are liable to to cause some damage

but i want to try to run everything the right way except 4th will be 3rd, 3rd will be second, etc.

yes, no maybe.....?


sorry about the huge train of thoughts but none of my friends are interested in this type of stuff and don't really like to listen to my excitement when i have an idea or get something done. this is the place and these posts are what keep me plugging away......

i give up for the night. and no time this week for anymore work on the truck so......next weekend
