    Pretty sure "010" means it's a 4 bolt main block.
    Couldn't find your code here. www.mortec.com
    Maybe someone knows another site?

    Well now I am stumped.
    I went and pulled the pan and it is a 4 bolt main.
    Dipstick is on the drivers side
    Crank # is 392442: 305 & 350 crank.
    It has the big damper on it.
    But the bores measure at 3.995"
    First I used my dial calipers on the snap gage and then used my 4 - 5" caliper but it was to big so I grbbed the 3 - 4" and got 3.995 again. /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif
    According to the casting # on the block (010) it can be a 283, 302, 327 or a 350.
    The 283 has a standard bore of 3.875".
    the rest have a standard bore of 4.00".
    This all started when I pulled the heads earlier and didn't see a stamp on the top of the pistons that people usualy put there to indiacte the over bore, all I wanted to find out was how much it had been bored over.
    I have never heard of a 283 with 4 bolt mains and I don't think anyone in their right mind would bore a 283 0.120" over.
    I think I'll drink a beer and go measure the bores again.
    Something aint jiving here and it's driving me batsh!t.
    Got the new cam today and wanted to have that pig smokin hours ago. /forums/images/graemlins/mad.gif

    what is the complete casting? most 350s up to 80 are 3970010. also what is the complete stamping on the block. you only gave the front which does nothing but tell the plant and date. i need the last 2 or three letters.

    3970010 is the complete #
    MM14289 is all that is on the pad.

    Nope just those ones.
    Stamped in bigger than sh!t, no indications of any other #'s or letters.
    I polished it with laquere thinner and a 000 steel wool pad just to be sure.

    I think Bruiser hit on a good point about it being an under worn block.
    All I know about the van it came from is that the old man that had it had the engine and TH350 rebuilt. I seen the paperwork and RO for the tranny $2200 /forums/images/graemlins/yikes.gif AAmco /forums/images/graemlins/yikes.gif
    Critters used the RO for the engine as a nest so I never did see what was done.
    He then had another fuel tank and overload springs installed and the morons ran the fuel line through a bracket and it got pinched off.
    I think between that and that clacking lifter sent him over the edge and he parked it and bought a 1 ton pick up. That was in 96.
    Well to make a long story short I think I am pickin my ass over nothing.
    Every block that I have broke open that had that casting # was already bored .020, 0.030 and so on.
    And all had that stamped on the top of the piston.
    I suppose that in 96 he had a fresh short block installed, that would explain the FelPro blu head gasgets.
    And reused the heads from the old engine. 624 castings with 1.94 valves.
    That would explain the 3.995 bore. 3.997 is the minimum standard size. And I was using a snap gage to measure so it's possible to be off a couple of thousandths.
    Kinda crappy though that the cam failed like that after 4500 miles, he paid for a warranty on the tranny and engine.
    No good now but...
    #2 exhaust lobe was pretty much round and no amount of ATF was gonna bring that lifter back to life. Another on the odd side was going out too.
    I think I am gonna stop scratchin my ass over nothing and stab the cam in it, seal it back up and go drive the damn thing.
