    It's the way that generation of car is designed. Dropping the k-member is the way you pull an engine/trans. It's a ton of work but in the end probably way easier than busting your knuckles trying to get to everything without doing it that way. Thanks!

    I have to pull the 2.8 to replace the rear main seal as it's been leaking since I purchased the truck. Since I was going to all that trouble I decided to swap the motor as well. It seemed logical at the time atleast? haha
    Going to rebuild the 3.4 so it will be almost like new and drop it in.

    ^ yes I follow AVE quite religiously. He's like Mr. Wilson from home improvement. I'm just finishing up a civil tech diploma right now. I'll be done in April, can't friggin wait. I work for a municipality full-time so balancing that and full time school has been a serious grind.

    I appreciate all the input. I find it interesting you want to ditch the mpfi? I was contemplating going that route but decided not to as I don't want to deal with all the rewiring. I'm already tbi, so I'm just going to hog it out a bit, swap in the 4.3 injectors and maybe a new prom if required. What did you do for your flywheel when you did the swap? I'm debating between buying a new one or just pulling one at the yard.

    As far as the electric fan goes. I'm going to do the swap + newer aluminum rad and see how it performs from there. The clutch fan was/is definitely working fine ( tested it). I hadn't thought about the dead air when running through trails you would see with an electric fan. The hardwired switch sounds like a winning idea for sure.

    Started stripping it down,









    even managed to get wifey involved








    Was quite pleased with how clean it was inside,



    Spark plugs looked decent, still surprised how well it ran with that air filter


    One of the dowels was frozen/corroded and I had a fun time getting the trans separated. Ended up using some heat on the aluminium housing and it did the trick beautifully, no pounding on it.



    Had to get creative to pull the balancer without a puller. Ended up spinning the main center crank bolt bolt back in, and placing a large wrench in-between it and the pulley and then screwing the pulley back on with the 4 bolts slowly until it popped itself off. Kind of tough to explain.




    Timing chain is super slacked,






    Heads off, and not looking bad






    Tough to see in pics but you can still make out the factory cross-hatching on the cylinder walls


    I just left the house yesterday and I was climbing a hill in the truck when all of a sudden the exhaust became quite loud. Pulled over to find an 02 sensor had decided to become two pieces.

    The timing for this to happen couldn't have been better as I had just removed the 02's from the camaro, and they were a perfect match! 15 mins later we were back on the road and on our way.


    We managed to get out ice fishing yesterday after that, very early ice so we got creative.
    Traded my paddle for an axe.




    We made out pretty good for only getting a solid hour of fishing in,







    Haven't sold much else since the last post. Definitely counting that 02 sensor towards my budget, called for a price on one and it was $30. So it wasn't necessarily a part sold as it was money not spent.

    charcoal Canister - $10
    Inner fenders - $10
    02 sensor - $30
    ______________
    Total $380


    571.50 - $380 = 191.50

    So the new total is $191.50

    Just a note about the cool teardrop camper you photographed a few pages back: It's available as a kit from Chesapeake Light Craft. They're a popular outfit for boats, but came out with this fairly recently.

    Cool looking pics Andrew. Do those old v6s have nylon timing chain gears or is that just something the old v8s had? Things are looking good. The ice fishing looks pretty cool too. Thanks for posting up. Cheers, Chilli...

    ^^ Spacer, thanks I had no idea. Pretty neat little trailer thats for sure.

    Chilli, I'll have to take a closer look but I'm fairly sure the gears are all steel.

    Picked up this engine stand for $30 yesterday.



    I've been avoiding getting a cherry picker because they take up so much space and I won't need one until I'm ready to pull the engine out of the truck. So I ended up tipping the 3.4 back onto the engine stand laying down and then had the wife help me tip it back up right. Sketchy indeed.





    Pulled the pan and mounts off, So far everything looks good.

    I bought a flywheel for a '92 S10 with a 2.8L when I did my conversion. It was like $55 new from Oreilly. I imagine Princess and Napa have similar prices.

    My timing chain was also WAY loose. (Vid on my build thread...) I assumed the engine saw very infrequent oil changes, or was run low on oil a lot. (Oil likely changed when the low oil light came on, or a while after...) A new timing set made it run so much smoother. I'd still like to rebuild it, but compression isn't bad, so I'll probably just toss on some new head gaskets and keep running it...

    You can do some research, but I don't think you will need to do ANYTHING to the 2.8L TBI for it to work with the 3.4L.
    My reasoning for this is based on my own experience... I put TBI on a 292 (4.9L) straight six in my old truck. I used a stock 4.3L setup off a '93-94. I thought going to injectors from a 5.0L was the right move, but it actually ran worse, and always had to correct from a rich condition. I went back to 4.3L injectors and it ran great.

    GM was offering the 3.4L as a direct replacement for the 2.8 in the mid-90's, and dealers were just dropping them in. It makes sense, since the the A/F ratio doesn't change with engine size, and neither the 2.8L or 3.4L are high RPM engines. I believe the flow of the 2.8L TB is sufficient, and the injectors seem keep up just fine to the slight displacement increase. Worst case, it may run a bit lean at really high RPM's, but I doubt you really spend much time at 5000rpm...


    Engine hoist... Find one with legs that come off and store upright... Like this one. I have the same one in black and orange, and it's been serving me well for years now, and takes up very little space when I don't need it.

    Thanks for the tips^ I've been eyeing a hoist like that locally but the guys asking $250 and I feel ashamed to offer him much less. I'm a couple months out from needing so I think I'll hold off for now. May borrow one from a guy at work for a flat rate.

    I've read that a lot of guys use 4.3 injectors because the 2.8's lean out at higher rpms. I'll probably go that route first and see how fuel economy is.
    For $55 or close that I'll likely just buy a new flywheel because it's just not worth the trouble for saving $20-$30



    Small update,

    Sold the entire drivetrain, trans, shaft, rear end.
    So I yanked that yesterday






    Did the old teeter totter and put the front end back in




    I need to get a buddy to move nearby or make friends with one of the neighbours because I tell you guys sometimes it sure would be nice to have a second set of hands.







    Wrecker just came and picked it up. Managed to get out fairly easily without damaging anything.



    Can't believe they gave me $63 and hauled it away. Sure frees up a lot of space in the garage.

    Trans/shaft/rear end $200
    Wrecker $63
    ______________
    Total $643

    643 - 571.50 = 71.50

    So the new total is +$71.50. Stoked to be in the green already.
    Still have a set of mags, front bumper, and a number of other parts I pulled off the car to sell.
    My hope all along was to pay for most of the rebuild costs by selling parts. Might not get it all covered but at least the bulk of it.

    Wowsorry to see that old Camaro go Andrew. But at last you have a motor you can build for your truck. I am looking forward to following your progress. Cheers, Chilli...
