October 2014, Gathering parts for new Sprint engine

Keeping track of bits with this useful gadget
Got a call from Mark Maynard that my block was ready to collect with its new liner installed and they have done a very nice job.  I spent an afternoon cleaning it off thoroughly in their wash tanks before bringing it home for a spot of paint. The bottom end has also been fully balanced which should help things along.
"New" block ready to start build


Started a little test fitting and tried the timing cover on the block - it was too tall!   Curses.  
Obvious really, they had to face the top of the block when they did the liner and now the cover was left about 10-12 thou proud so I had to take it back to be matched up.

The machine shop had also made up a few tappet shims because the re-profiled cam needs thicker sizes than the standard range so I can get on setting up the head.

  Fun job starts here.

And when all the valves were bedded in it looked like this



 I hope I put the valve springs on the right way up!



I don't need to add anything about this picture except the one you need is always missing!

 






The two pictures above show the differences between a standard TR7 flywheel and the Dolomite Sprint one. The TR7 has quite a bit more material on the rear face but the important working dimensions are the same. The Dolly one is also about 2kg lighter so guess which one I will be using?
Crank with the Dolly flywheel all balanced up.
