car4jim Jim The best way is to goto a machinist and let them either boil the block or bake the block in an oven. If you can find a dealership mechanic with a Cuda machine, this will power wash the block with boiling solvent. It will clean 95% of all the crap out of the motor. The rest is with wire brushes and scrapping. Clean with simple green and warm water. Air dry and paint the block. all amchine surfaces like the cylinder walls spray with WD-40 and bag the motor to stay clean. Before cleaning you might want to run a tap through every hole in the block. This will get out the garage that ends up in the bottom of the holes. Good cleaning takes about 2-3 HOURS. Brush kit you can get from Jeg's or Summit. Rick L. Ps becareful where the waste water ends up.
