    Okay, now that I have replaced my 305 with the new 350, I am trying to figure out what to do with the 305. First I plan to tear it apart and use it as a teaching tool for my 15 y/o. But, then what to do...

    Is there really any difference in the BLOCK between the 305 and the 350? Or is it simply in the crank and/or the rod length? Could I take a 305 block, bore it 030 over, and install a 383 stroker kit that includes the 400 crank and the new pistons and all?

    The only stroker kit for a 305 is a 331 kit from powerhouse.

    Why? What is the difference between the 305 and 350 block? Is the block's bore size different?

    305= 3.736" bore(350=4.0"
    3.48" stroke(same as a 350)
    all small blocks but the 400 use 5.7" rods

    Guess that'd be a bit much to try and get bored to match! Anyone got a 350 block they wanna give me?!?

    yeah that would be a bit too much to do[​IMG] and I don't have an extra 350.

    305 blocks make excellent boat anchors or else can be modified nicely to work as a beer bottle holder for the garage [​IMG] LOL

    haha my friend is selling a 305/700R4 combo for just the price of the 700. Those engines are tired off the assembly line. Silly GM trying to build a fuel efficient V8.

    1986 GMC Jimmy 6" springs 3" body, 38/15.5/15 Swampers, 14-bolt FF rear, Dana 60 front, 1991 front-end.
