Finally pulled the engine yesterday. Cylinders looked and felt great. No
gouges or obvious signs of excessive wear. Pistons had slight scuffing,
but the rings had a lot of verticle movement. Crankshaft had considerable
wear at he connecting rod bearings, but the main bearings were good. Cam
had worn spots (along with the tappets) on four (possibly five) lobes.
Thrust washers on crank had wear started, but the were no bad . Several
valves were not seating fully. Oil pump had wear, but not too excessive.
After talking with the guy doing the engine work, he suggested the
following:
1) Machine the bad portions of the crank and go with undersized rod
bearings
2) Replace the pistons and rings to prevent a ring from failing in the
near future.
3) Replace the cam and bad tappets.
4) Replace the valve guides and valve seats that are bad. Inspect and
replace the bad valves on an individual basis.
5) Replace the oil pump.
I would like to improve the performance of the engine above stock (but not
to a racing level) and am looking for suggestions on where to place the
emphasis based on what needs to be done to the engine. Also looking for
good sources for the parts needed.
The block and head will be sent out this week for cleaning (dipped at a
local shop the does alot of tractor work) and work will not restart until
after Christmas.
The remainder for the restoration is progressing. Both seats have been
rebuilt and the dash refinished. Body work is about 85% complete with the
only major work needed is ensuring the front valance mates up to the
bumper.
TIA
