    Anyone? just a bit of info I wish I had in my knowledge base. Whats a full assembled 4.3 weigh? how about a small block? Next project is an S10 and though I'm likely just puting a 383 in it and rocking it, a 4.3 isn't out of the question.

    yeah forget that, 383 /forums/images/graemlins/rotfl.gif twice the torque and only 150 more lbs. Not to mention eventually aluminum heads will shave a little weight.

    My uncle has a 2001 S10 with a Vortec 4.3 with nology wires, K&N intake and a chip and its one quick little truck. He also gets about 25mpg around town.

    I like the 4.3's, I have one in my 95 full size 2wd. They are good motors for normal driving but won't take abuse very well. They won't rev as high as a small block and come apart real quick if you try. I bought a 95 Sonoma brand new, it had a 4.3 with a 5 speed and got 2 new motors under warranty.

    Isnt a 4.3 the same thing as a small block cut down. Why would the 4.3 be weaker? Smaller mains? Bad oiling?

    [/ QUOTE ] IIRC, the 4.3 uses the same bore and stroke as a 350. Just missing a couple of clys. I could be wrong, but I thought it used the same bearings, as the 350 also.

    Exactly, so I would think the 4.3 is a tank

    You are correct Sir. The 262 (4.3) is nothing more than an abbreviated 350 and also has a medium journal crank. Just as strong as a 350. I would love to see what a stroked 4.3 could do. I have heard that they can be bored and stroked to around 320 ci. I think a built 4.3 would be just fine in an S-10 with the right gears.
