Deburring is done to: 1) to remove sharp edges that can start stress cracks 2) to remove casting "flash" that could later break loose and fall into the engine and 3) to smooth surfaces inside the lifter valley to promote oil drain back. On the outside of the block, only sharp edges and flash were deburred. Casting numbers and other symbols were left as is. Block deburring takes about three hours if you have proper materials. I used a die grinder fitted with either sanding cartridge rolls or small sanding discs in 60-grit suppled by Standard Abrasives Incorporated.

Another task related to deburring is clearing the water

I just replaced my rod bearings in my 300 and i can't get the engine to move. I thought the bearings were to big but they are the standard size.

 

Lukes,

make a new thread- new topic- more likely to get more of a response. Add more info like why you used standard size- new crank? etc. also... you turned the motor over after installing each bearing to align pistons- when did it get excessively hard to turn. yada yada yada...

experts here will help you- but most will not see your post on my tired old thread. good luck

 

...Welcome Lukes, to Ford Truck Enthusiasts!

See you on the boards. ….
