additional galling on shafts from lack of oil to the rocker shafts.

Rebuilding and Checking Carburetor

This was the powdered residue in the bottom of the float Bowl from the contaminated Fuel Tank likely. Fuel filtering system needs updating in the system prior to reinstallation.

Cylinder Block Update

Note Top of Bores not cleaning up

Driver Side of block measures 4.260"

Passenger Side of block measures 4.255"

Pistons (two different sizes in engine???????)

Note the smaller 4.255" pistons have no machine marks on bottom and larger 4.260" has two circles.

Deck Height OK at 10.156 and is Square

Sonic checked block 1/21/08 and can be cleaned up and bored to 4.270 OK

**************************12/21/07*************************

Exhaust cracks on all runners both heads 12/19/07 all else OK.

Block Magnaflux OK with exception of small crack in rear main saddle oil hole

Rear Top/Center Oiler Oil relief spring and plunger not in block (blocked of by builder)

Three types of Spark plugs in motor (plugs fowling?)

Interested in knowing which side of motor the rocker arm stand bolts came loose on causing significant oil pressure loss to either #2 or #4 cam bearing early on in motor life.

All of the rod bearings showed significant wear on one side of bearings against the crankshaft.

What measured oil clearances did engine have at assembly on Rod and Main Bearings to Crankshaft?

All five cam bearings have significant wear on bottom of bearings and Side Oiler bearings were installed.

Did not find any other obvious assembly errors causing damage but impossible to check rear main torque or oil clearances or the rods that were damaged. Rear crank to drive alignment questions along with excessive exhaust gases in engine. OK
