A customer brought in a Gen6 BBC with 3 missing main caps, we installed Billet caps, rough line bored and finished honed it.

    Looks like with the difference in hardness between the steel caps and the cast bock that the block would hone faster than the caps.

    How do you compensate for gravity and the hone removing more at the bottom, thus moving the crank centerline closer to the cam? Mike

    Very nice job Daniel. That should work real good. What spring pressure you run on the pressure feed on the mandrel? I usually run about 3. I did not know where you run with those caps. Take care, Ed.

    That is intresting, wondering if you count the number of strokes of the honing bar when honing. No doubt that takes a lot of experence to sneak up on the clearence you want. This is a great video

    Just asking, when line honing, why didn't you torque the oil pump that you're gonna run on the rear cap? Doesn't it pull (distort) the #5 cap when it's torqued down AND then checked w/the pump torqued down? Real nice informative video! Thanks

    Do you do anything differently if the caps are harder than the cast iron block? The way line honing is done it would appear difficult to get all five mains the same size.

    Generally we don't, as we wouldn't want to move the crank centerline up, but there are instances where we would trim the block side .

    Why isn't line boring good enough or just plain better than line honing crank mains? How is line honing going to straighten out parallelism between the cam tunnel and the crank mains? I don't believe a cross hatched finish on crank mains makes any difference. I realize the fixture shown below takes longer but isn't this a better way to go for someone who cares about precision and reducing friction? kzread.info/dash/bejne/o6d8xdqOm7eXfpM.htmlfeature=shared

    @powellmachineinc3179 Honing isn't more accurate. A single point turning tool is more accurate in providing location. Honing does, however, leave a superior surface finish. I fail to see why a quality bored surface finish isn't good enough to support a split oil bearing.

    I don't get how line honing doesn't make the crank uncentered or crooked. It's just free floating.

    It's a fair question. If you aren't willing to try and answer it than STFU. I was a CNC machinist for 25 years. I did my best to answer his legitimate question. There is no such thing as a stupid question.
