    I´ve been gathering new and used parts from Finland and USA also. I have almost all the parts now. Gaskets and bearings are still on the way from Summit.

    Now that the motor is in pieces, I have ported the heads and the intake a little bit. Next step is to change the pistons to a set of used but ok connecting rods. I´m going to balance the pistons and the rods first. Then I´ll take all the internals to have them balanced and maybe change one intake valve seat that has a few small chips come of the side of the seat.

    Pretty sharp and tall ridges were in the combustion chambers:

    I made a set of "seat savers" to be able to grind the chambers without worrying of hitting the seats:

    In this picture you can see the dark area between the seat and the light that was extruding from the wall and the bulky intake valve guide:

    The other side was concaved as you can see from the shadow:

    Cleaned up:

    That much had to be aligned on the intake:

    Aligned and cleaned:

    First attempt to remove pistons from the rods failed:

    So did the second one:

    Third attempt started by building a press:

    The jack cost 13,90€ and the rest was from trash metal.

    After that I had to make a tool to use with the press:

    After that it was a success:

    Thanks guys.

    Tonight i´ve been cleaning the gasket surfaces. I hate it o_O But it´s actually not that bad since I have a few beers, a dram of Jack Daniels` and the live stream from Drag Week on the side :) Now it´s 1:40am here in Finland so I think I`m calling it a night...

    I couldn´t use the special tool with my pistons, because the gap between the piston and the connecting rod was so small. I had to press them out against the piston.

    I replaced the rod hardware with ARP stuff. After that I weighed the rods and their top ends separately.

    [​IMG]

    6 of the rods were very much identical, but one was over 10 grams lighter on the top and one was lighter on the bottom, so I had to grind all of them pretty much. Now they are within 1g. The pistons and wrist pins were within 1g from the shelf.

    The new crank had a bit of rust on the surface, but it came out alright after some scrubbing.

    Today I took the rotating assembly to be balanced, there they will check the journals and polish them if needed.

    Last week I assembled the pistons (all except one, they needed it separate from the rod for the balancing).
    At first I tried to press them in, but the piston felt a bit sticky so I took it off again and decided to use heat.
    After that I made a rig to hold the piston and stop the pin at the correct depth.

    [​IMG]

    I put the pins to the freezer and heat the rod until it just started to turn blue and then pushed the pin in. I had to redo a couple since I didn´t get them all the way in at first, but in the end I got them all and now they move nice and freely.

    Excellent work you're doing. I'm impressed. I prefer doing everything I can myself also.

    I made a short "tutorial" of the piston assembly:
