    "2.8 performance" is an oxymoron (like jumbo shrimp).


    I had better luck with the 4 cyl.

    I usually V8 them.

    I think it is almost "bolt in easy" for a carbed 350/350 but the real question is what is your budget, mechanical abilities and shop like?

    Sweet,

    Honest intellegent answers! Pretty sure you can get it done or at least ask the right questions and take pictures to get the help you need.

    THE s10 v8 swap book is pretty good reading for those not familiar with Ss-wap although there is quite a bit of info on line.

    add $1000 for
    mounts
    radiator
    shifter?
    exhaust
    possible driveshaft
    cherry picker, LOL (all good projects justify a tool)

    Don't forget
    beer and pizza for the V8ing party, LOL.

    Here's my advice to you. The V8 swap is not for the faint of heart but if that's what you want,go for it. The other choice is to install a 3.4 from a 93-95 camaro or gm crate engine.These start at 160 hp and can be modded up easily to 175-180 hp,it's a bolt-in swap.You can keep driving you're 2.8 and sale it when you do the swap. I recommend the gm 3.4 crate egine if you can afford it,if you buy and rebuild a used 3.4 you'll have at least half the price of the crate. I have a V8 and a 3.4 blazer.

    i also recommend a v8. you won't get any worse gas milage than your 2.8 gets now. i would just keep putting money aside right now and just read read read about the swap as much as possible.
