    on the front of the block where the fuel pump is. there are 2 bolt holes. one on the bottom and one about an inch and a half above, the top has a bolt in it. what are these for? was thinking about running a bracket down to those and wanted to make sure they weren't something I was gonna get in the way of.

    There should be , on older carbed motors , bolts holding the fuel pump mounting plate on , and then the fuel pump mounts to that . /forums/images/graemlins/k5.gif

    I think a while ago, i found one of them lines up with the pushrod for the fuel pump.. Probably the top one you said has a bolt in it.
    I was trying to change a fuel pump in a '57 nomad and was VERY tough to get your hands in there, one hand holding the pushrod up while you get the fuel pump in there and a bolt started...
    I got an extra long bolt and threaded it into one of those holes in the front of the block, so it would hold the fuel pump pushrod up... Then i wouldn't have to worry about holding that pushrod up while i get the fuel pump in there. i could bolt on the fuel pump, and lastly remove that long bolt, and put the short one back in... I think it'll probably leak oil if you leave that bolt out, maybe not. /forums/images/graemlins/dunno.gif just make sure its not long enough to interfere with that pushrod.

    Yep the top bolt will leak like hell if you leave it out..... You'd be better off taking a quart of oil and pouring it through your fan with the engine running than leaving that bolt out..... /forums/images/graemlins/smile.gif

    Are you meaning on the very front face of motor, not where fuel pump is actually mounted ? I always thought those were for early shoebox motor mounts /forums/images/graemlins/k5.gif

    Those same 2 holes are on the other side of the block also. On earlier model chevys those were motor mount bolt holes. I have a '58 chevy truck that uses them, also as stated, used on 55-57 chevys. My '87 block has the"holes" just not drilled and tapped.

    I thought so, they kept those , even though a lot of people just make new side mounts on their shoeboxes, stronger than the front mounts ever were /forums/images/graemlins/k5.gif
