yep i have cut blocks out for 4.750 for alum rods there no ez way .i set the crank in with a piston wipe the wall down good .i put some lube on the skirts so not to mark up the pistons or bores as well as the crank/rod bearing s. you do not need to put all of them in number 5 and 1 will work i have old set up bearings for this job as you do not want any iron dust on the bearing s if so they will turn in to a file and trash the crank .you will have to trim the bottom of the bore cam side and oil pan rail side i turn the crank by hand till it hits then use a big tip marker they are about 1/4 tip .mark out all bores .you want to grind 1/2 of the mark off so about 1/8 of the mark still should be still there . when you grind all the bore s you need to take a 80 grit flap wheel and roll the bottom of the bores if you fail to do this you will trash out your new pistons and bores and have nice new junk . if you want to P.M me i can talk to you on this. if you want. when you get this all done wash your marker marks off the bores clean the block so no iron dust will not hurt any parts , put crank back in the block rod and piston turn by hand. i make up long card boad feeler gages to check for any thing hitting you need about 060 for room. if you do not have that but will roll thru then i mark the spots with a thinner tip marker. take all parts out grind and roll the shape spots off the bottom of bores wash good and check it till it rolls and you have 060 .if you have a older 427 block and you grind to much you will hit water
