    Best valve seat material?

    I bet he is speaking of, nickel colbalt alloy. I talked with my sales rep. from CV Products about this. There is a patent on this alloy, out side of that, they have not seen a reason to offer it. I questioned him on the copper alloy seats I use, as far as being soft, that I don,t believe. I have...

    oil cooler reccomendations?

    Fixxxer22 As said, by Eddie and Bob, always check the lifter bore clearance not only for clearance, but also for being out of round. The Morel, lifter is what I use on every build. The problem with any lifter is the clearance and any side loading of the lifter, caused by the bore not being true...

When bleeding after rebuild, of course you want to fill reserivor, cap the down fittings on the trim line manifold block, tap the up button until clear fuild comes out of the lines, then connect up lines to cylinders, trim up keeping the tank full. Once...

    Dart 10.200 and 8-71

    No crank, rods or pistons. It was one of those deals, I ordered, pistons, rods, cranks and the guy forgot to mail the money over a 6 month period. So this is what I have left over. This was 3 yrs ago.

    575 internally cooled?

    If you already have run this in salt water over time, I would question at this time of adding a closed cooling, unless you have this torn down at this time and are rebuilding it. You would have to have the block shot blasted and the heads to remove rust scale.

    Dart Big M 9.8 short deck

    The 11.100" deck height block is going to allow you to run more stroke and lower the rod angle, by reducing the side load on the cylinder wall. Depending on what stroke, rpms you will be running is going to limit you. The mass of the rotating assembly is still a factor.

    Dart Big M 9.8 short deck

    The 6.585 lenght is odd, but not if Merc did it. It's not an standard rod lenght for off the shelf.
