    Well your buddy is full of ****, the 6.2 is a completely different motor than the gas engines. The only thing they have in common is they are OHV V8's. 6.2's weigh about 650 pounds from what I remember. Small blocks are about 550 pounds and big blocks are 750.

    Why do people always say 6.2 are based off gas engines? My girlfriend's dad swore up and down the 6.2 was a knockoff of a gas engine till I took him to my shop and showed him a disassembled wersion of each. Some people...

    Honestly it wouldnt suprise me if they were because they have similar external dimensions but I've always heard 650 lbs. Kind of a medium block.

    I guess I meant that the size is about the same as a BBC, not the SBC.
    I heard that Detroit Diesel is the company that designed the 6.2-6.5.

    Many people think the 6.2L diesel ("It's a Chevy") is the same as the 350 diesel Chevy used in some pickups ... even though that, IIRC, was an Oldsmobile thing. It was an abomination, as we all know :D

    Anyway, if memory serves, THAT diesel was based on the gas 350, and gave all diesels, especially Bowtie ones, a bad name.

    Olds Diesel

    The sad part is if you want to build a rocking sb olds you use a diesel block, did it once, i couldnt find one that didnt run, and the guy i bought one from even paid me $50 to pullit out so he could sbc it.... :D

    The later syle 350 DX blocks were pretty good. I've heard the same thing about people taking these 350 diesel blocks and building a nasty 383.

    Dry weight of a 6.2L (according the big green military crate that mine came in) is 655 lbs. Add on accerssories and everything else needed to make the engine functional, and I think you're looking at about 900 lbs.

    The last info i read regarding the use of the 5.7 Olds block for a nasty gas engine was that they could be built to 440 cid...

    Not sure all that would be involved though.

    Sounds about right to me. 6.2s seem so much heavier than a gas.
