    I have a 91 Blazer Silverado 4X4 With 33's and a 2 1/2" suspension lift with 456 gears . I am going to replace the Engine and I am leaning towards buying a GM creat motor. I tow a trailer 22' when we go to the dessert and need more power. Help!! I don't want to buy a new truck. /forums/images/graemlins/confused.gif /forums/images/graemlins/k5.gif

    IMLAO you got right, stick with a GM creat motor. they cost a lil more but you get what you pay for.
    befor i knew better i had a loacal shop build and install a new motor for me and i still regret it 3 years later.

    Do you have a local engine builder ??? Those guys can usely beat the big places prices and offer just as good of a warrentie, if not better. Also lots of local engine builders will build you a 383 stroker to your specks, built more for your app., the big chain places all build a basic engine. I'd go for one built for more low end torque, and around 9 to 1 compression. With the custom built engine you can get a cam more for low end torque also, without haveing to do a cam swap later costing you more money and possibley voiding your warrentie. Just something to think about.

    That sucks, sorry to hear about it. I've delt with local engine places and have had good luck. Had a 454 in a 77 Monte Carlo that was a very good deal for me at the time. Engine was still running strong 4 years later when I sold the car, and I beat the $hit out of that car almost daily. (I was in my early 20's when I had it.)

    If you want more power.You might check out either of these 2 crates desighed for your 91 with TBI
    sdpc2000.com TBI 350 HO

    sdpc2000 TBI 350 Vortec HO
    Both of these engines should work with the stock chip in the computer. But I dont think you willl get the claimed HP with the stock TBI and chip.

    I would suguest modifing your TBI also.
    These guys can help:
    turbocity.com
    I use a lot of their stuff and it works pretty much as claimed.

    Why not build your own?
    Get a 4-block main, some vortec heads, any dual plane intake and you've got a good engine. 350 rebuild kits cost as little as $155 (new pistons, rings, all bearings, cam, plugs, gaskets, lifters, chain, etc.) Buy a few books, buy a few tools, and just do it.
