[6pack] Engine Progress

[John Cyganowski]

I separated the head and short block and brought them to the engine shop. I 
finally got a look at things today.

I had everything hot tanked. They have magnafluxed the block, crank and 
rods.  Heads (mine + a spare) have been disassembled, hot tanked and bead 
blasted. They will be magnafluxed soon.

Pistons seem to have some light scoring/wear on the skirts sides. My thought 
is to replace them. Why are forged pistons for the TR6 $150-$200 a piece? 
This seems outrageous. County brand seems like a low priced cast 
alternative, but worry about going with the low bidder here. What are my 
options for cast?

Block is stock bore. They put a light hone on it and are recommending 1st 
oversize (0.020"?). Crank journals are stock.  They will polish it and them 
make a judgement if we need to go futher.

Cam is the 10-50-50-10 cam.  Lobes look okay but the fuel pump eccentric is 
worn.  I am going to replace the cam.

Things are much cleaner.

Next seems to be the rods.  I guess I need new bolts and small end bushes so 
they can start.
