Blackwater, Here's your up date. I hope your trip is underway.
It seems that my magic number today was 0.016". That is how much clearance there is between #2 rod and the fuel pump lobe of the cam.
It is also how much the pistons stick out the top of the hole.
The rod bearing fit is going to be on the tight side but within specs like the mains. This is going to be a tight little engine for a few miles. I think I'm going to clearance the cam a little just to be on the safe side. I'd ilke to see about 0.030" there. I'll stick the other two pistons in and check that out. I have another 0.040" over block that may have a little taller deck. I can turn the pistons down some the top land is thick. A quick reminder of parts. BLOCK-0.040" over 153, 181 CRANK and RODS, tlowe's forged flat top Ross 250 Chevy PISTONS. I have a 0.040" thick copper head gasket. I have no idea of what the valve/piston clearance will be.
