    Don't qoute me on it , but last time I saw a write up , the bellhousing stayed put . The engine was longer by two cylinders at the front . Electric fans would be your friends .

    GO TO S10 EXTREMIST NOW

    look up the 3.4l camaro swap, i did that on my last truck, felt like it doubled my power. plus i went from 14-15 mpg to 19-20.

    it was an easy swap

    my truck was an 87 5spd 4x4

    There are several sites with plenty of info for doing that swap. You will need the mounts, rad(aftermarket or from a 4.3 truck/astro van) You can use a mech. fan if you place the engine back on the mounts, You will also need the oil pan for the swap. It can be fabbed from the top of a sb pan and the sump from the 2.8 pan,or may be purchased from a coulpe sources. Then use a 2.8 pick up tube. Then you will have to decide on headers or manifolds. If you choose manifolds the best choice is the low performance third gen camaro. There may be others that fit but these will work the best for clearance with the steering column. It may seem like alot of work but the results are more then worth it.

    there are engine mount kits and exhaust kits for this
    hope you have some $ to waste


    2.8l is a good little engine, i have one in the 91 and it runs drives like brand new

    must be your carb thats messed

    mines TBI

    i swore it was a 4.3L truck til i popped the hood only to see a non-4.3L in it, i was like wow its not a 4.3!

    it runs like one though

    good little engine :D

    ive never personally seen anyone with any trouble out of a 2.8

    i see alot of oil burning and other problems with the 4.3 alot though

    good luck

    Forget the stock tranny, you will burn it up the second you hit the gas.

    4 bolts are typically stronger, but it doesn't matter much unless you are going for over 500hp.

    You never said if this was 2wd or 4wd. If it's 2wd, then you don't need to get an oil pan, or fancy headers, or anything fancy for that matter. Summit has engine plates that moves the whole engine forward, IIRC it was $100, and a total waste of money. I used headers from Summit, can't remember the brand, but was only $100 or so. Have to clearance the firewall some, but not much. Biggest radiator you can fit, and stock mech fan will fit, just close. If its 4wd, then can't help yah, never did one.

    The tranny will not bolt up as the 2.6 is a 60 degree engine vs the sb being 90 degree. They have different bolt patterns. I could scan the advance adapters book of the swap if you want, it will give you a much better idea of what you will need to do the swap.

    If you decide to do this I have the motor mounts, jtr book, body lift kit, exhaust manifolds, and maybe some other stuff.

    P.M. me and let me know
